Schaeffer Oil - 500,000 Mile Engine Tear Down

[SOUTHBAYDIESEL]

I might buy the oil a sponsorship would be nice.... His nails in the video are pretty gnarly , maybe he should get some creme for that and wear gloves for now on

[KB3MMX]

Schaeffer Oil sucks.

[svtlincoln]

It's a single overhead cam design you dumb fuck.

[SrgScream]

those are some bad nalis. hard not to notice

[scdevon]

Modular Fords are the most durable American V-8's ever made. There things will last 500,000 miles running olive oil.

[scdevon]

@scdevon I mean "those" things.

[sensifan]

@scdevon But how many spark plugs have they spit out before hitting 500k?

[nightmathzombieethan]

@crombieposterboy LOL Yeah, i hate to be a doubter but I was thinkin the same thing...they weren't just sludge-free, they were nice and dry too...

[maersklandro]

That's a SOHC engine any day of the week.

Two SOHC 4 cylinder banks.

And the thrust half bearings are in very good but not excellent.

[BBHumb1e]

Two words "Schaeffer Advantage"

If you use any other lubricants your are wasting your money. I highly recommend yall to find a distributor or a shop/store that carries schaeffer's!!

Won't use any other lubricants, fuel additives, or de-greasers.

[faostube]

@birdman1900 On some level you are correct but when you go to school, you'll know this. Its a DOHC because its a V type engine. Don't judge if you don't know what you are talking about, hope you dont take that rudely, studied at UTI and this is one of the scenarios people always get wrong.....trust me, they know wha they are talking about.....if it had 2 cams on each side it would be a quad-cam .... we can however, say each bank is a SOHC but the engine itself is DOHC, do some research -)

[FixFalcon]

@faostube birdman1900 is correct. When it comes to the Ford 4.6L, SOHC means ONE cam shaft per head. DOHC means TWO camshafts per head.

[traxxasmaxx33]

So am I supposed to trust a "mechanic" that can't tell the difference between a DOHC and a SOHC head???

[SPQRImperator]

@traxxasmaxx33 I thought the same thing.

Go easy on him. He can't count...or trim his goddamned infected fingernails.

[06Duce49]

yes

[points2shopPROOF]

is that the same engine that my 2005 f150 has? 4.6

[FordsRule351]

someone needs to quit smoking,,,,

[gteraka]

@birdman1900 Its hard to believe what he is saying if he doesn't even know the design type of his engine.

[FixFalcon]

HOLY FINGERNAIL FUNGUS!!!

[SPQRImperator]

@FixFalcon lol

[NoobiiPower]

How can a 9 year old have 37 years of experience ?

[spaztack]

Amsoil for life. Btw, i highly doubt that is 500000 miles.

[KB3MMX]

Amsoil would have went twice as far.

[meronmotors]

Somebody did the head gasket on that engine at somepoint you can see clearly. So only the block and oilpan are relavent. Still good only thing is see thats not soo good is at 5:23 the oil ring is full of burned oil sludge it appears like its stuck but it looks like a 200,000 mile engine not a 500000

[sweetlikeADAM]

Once again, you ignorant piece of shit, there is a difference between grammar and speech. Also, I didn't read what he said, I HEARD what he said because he was SPEAKING. If you would have graduated elementary school, then you would know that. And yes, I obviously misunderstood what he said and corrected myself. You are obviously a complete idiot. And you call me "hypo"? That's a fucking prefix. You can't use that as an insult. Now go steal some more video to upload to your channel or at least re

[sweetlikeADAM]

@birdman1900 No, one camshaft for each 4 cylinders, dumby. That is still SOHC.

[davidzzz94]

@sweetlikeADAM so... he said its a sohc, and u said its "still" an sohc, and ur the calling him dumb? r u retarded?

[sweetlikeADAM]

@davidzzz94 Judging by your improper use of grammar, you are the retarded one.

[davidzzz94]

@sweetlikeADAM HAHAHA ohhhh kay "english major" there, who said i was born in a place that spoke english as the primary language? who said u have to use "proper" grammar while typing to retards like u? yepp no one, nice try changing the subject thou, but now u r just... retarded man, i cant think of any better description than that for someone like u, and if u were so good at grammar, how the hell did u misunderstood the other guy in the first place then? and end up repeating what he said? idiot

[sweetlikeADAM]

@davidzzz94 Well, if you are going to use a website that was created in and is based in America, a primarily English speaking country, you should use proper English. And if you are going to be arguing with someone, you should use proper grammar, otherwise, you just sound like an idiot, which you do. If you can't think of any better insult than to call me retarded, then you're obviously a well undereducated, ignorant piece of crap. Quit wasting my time.

[davidzzz94]

@sweetlikeADAM oh ok, once again "english major" how did u misunderstand what he was commenting about the first time then huh? i thought u r the best at grammar and least idiotic eh? ur the fucking hypo here, if u were any good at english then u wouldnt have had to repeat what he said as if he was wrong which he wasnt, and make ur self sound all heroic, yeahh exactly, quit wasting time typing so neatly anyway, ur the one that couldnt read for shit in the first place

[sweetlikeADAM]

@davidzzz94 ad a book to educate your third grade level brain.

[davidzzz94]

@sweetlikeADAM so i finally got the best out of u eh? what happened to ur capitalization for the first word in a sentence? english major? and whats that first word in ur sentence? ad? ad a book? yeep thot so, so u ARE retarded, wow im so surprised

[sweetlikeADAM]

@davidzzz94 Did you not see that that was a continuation to my other comment, dumb fuck? Obviously, you're an idiot.

[davidzzz94]

@sweetlikeADAM oh shitt im the dumb fuck now XD laugh my fucking ass off, who mis read and caused himself to look like a retard in the first place? yep that was u

[ikester7579]

And one more thing. Amsoil has been in bussiness for over 35 years. And they are only second in sells in synthetic oil to Mobil one. Now how long has shaeffers been in business, and how big is it? Considering most of Amsoil's foundational sales were done by word of mouth on how good it is, And it grew as big as you see today. what does that tell you about it's products compared to shaeffers? And Amsoil does not use outdated technology like Molly which is an additive for gear lube.

[ThePomash]

@ikester7579 Why are you bashing a product that you never used just because you decided to like another one.

The answer to your question is on Schaeffer's website. They're in business since 1839 and are the oldest lubrication company in the US.

BTW, I used them both and Amsoil is not the better one. At least that's what an independent lab said after they analyzed my samples.

[ikester7579]

@ThePomash

How many classes have you taken on oil? Can you discuss oil all the way down the the molecule level? Do you know the difference between chemical wear and frictional wear? Do you know what the Shell 4 ball wear test is? Do you know why shaeffers does not do such a test? Do you know why Amsoil is only second in sales to Mobil in the synthetic oil market and they have only been in business since 1972? And Shaeffers since 1939 and how big are they? Also, Molly additive is way outdated.

[ikester7579]

@ThePomash

Also you notice the reason the engine is so clean is because the owner did regular flushes with a product they call neutra in the video. Amsoil has a superior detergent package and only use premium synthetic base stocks that don't break down under high heat conditions, Which eliminate the need for constant flushing even after being used for 25,000 miles before changing it.

[ikester7579]

@ThePomash

I went to the site as you requested. I found it very vague in terms of technical information as far as someone educated in this field would understand. But I found the MSDS sheets interesting. If you look at: #167 Moly Full Synthetic Gear Lube ISO 150. You will find the terms: Petroleum Hydrocarbons and Additives. Synthetic oil does not contain Petroleum hydrocarbons. 

[ikester7579]

@ThePomash

Towards the end of the video you will notice that they pick up a piston and move the rings around. Notice how they do not focus on the oil rings. Which is the bottom ring. So I made the video full screen to get a better look. The oil rings are gummed up and is the reason they don't really focus on it. When they pan over the other pistons on the table, pause the video in full screen and you can see the gummed up oil rings on every piston. Good oil does not need a cleaner added to it.

[Teleblu73]

wats up Timj !!

[HARDNADER]

I've seen Thomas Muffin trucks with 350 4bolt main, with 200k and look like this, using Kendall

[gokartmaster123]

@birdman1900 I think these guys smoke crack im not going to have them work on my car if they cant get it right... Oo wait i work on my own car so i dont need to worry

[HarmonyStar22]

@gokartmaster123 they r not working on a cra they are taking this shit apart not on crack you are i swear i read one more thing about them being on crack iim going to slap them

[ikester7579]

@HarmonyStar22

And here's another fact. There is a reason only "pure" synthetic oil is used in jet engines and not shaeffers. Want to see why for yourself? Take your best shaeffers oil and Amsoil 100% synthetic and put them both in a test tube. Take a propane torch and heat them both up and see which one breaks down and turns black. Make sure the test tube are pointed away from you in case of a fire flare up. You can do it in a frying pan to if you like. You will get the same results.

[apintonut]

these guys need less drugs 500k ? why they showing off a ford that only lived half its life my old ford work truck 300 inline six had 500k on it when i sold it and it drove away and i still see it driving around time to time and my first car a ford pinto had 750k on it most of that pizza delivery miles never had engine troubles with ether the pinto did go though 3 tranys and both started to need chassy repairs around 500k current truck has 278k pn a 95 f250 302 and still going

[candle3k]

What they didn't tell you, is that they threw those parts in the parts washer real quick before filming =D

[candle3k]

@birdman1900 Mmm, There's technically 2 cams. So, technically it IS a DOHC but not exactly is. It's a SOHC per head, but 2 cams per engine..

[silvermach2002]

What a bunch of corporate douche bags. These guys barely know what they are talking about.

[panthermike]

Which grade of 7000 was used? 5w20, 5w30 or 10w30?

[WilltheWang]

thumbs up for hands that look like gondor's

[oscartheiguana]

wow thats amazing...........for a ford... lol and tell the guys partner to smoke another 1

[wootness3000]

These guys don't know much about engines. That's a SOHC not DOHC, there's only one cam on each side.

[jayshieldsEX]

@wootness3000 We know. Good catch. Not many have caught that, but the YouTube community is pretty good. Thanks for your comment.  Jay Shields, Pres. of Schaeffer.

[BlakeMason2]

Turn off the ***dammed cell fone. hahah!

[nightmathzombieethan]

WOW!

[founditnow54]

lmao that guy was pissed when that phone started ringing!!!

[NitroGadvRules]

@birdman1900 nope, your wrong, single over head cms have 2 cams, dohc cams have 4 when in a v8. Theres two cylinder heads.

[pcpti]

i thought that was MY phone ringing!!!!!!

[06Duce49]

Great stuff. schaeffer has been doing this since the 50s.

[slickstuff68]

I have used Schaeffer in a 97 Chevy 1500. I have 426,000 miles doing 1/yr oil changes and oil analysis 2x per year. Last year I had over 42,000 miles on the oil. I plan on tearing down and filming for uTube.

[06Duce49]

slickstuff. would like to do visit when you tear down the engine and also film. if you don't mind please contact schaeffer tech department at 18003259962

[wolfc70]

That is a SOHC motor, not a DOHC. There is only a single cam per bank (two cams total), hence it is a Single Over Head Cam Engine. A Double Over Head Cam engine would have two cams per bank (4 cams total).

[Chevrolet8608]

somebody please tell me what he means by nutra?

[dsmith308]

It's a Shaeffer's fuel additive.

[06Duce49]

ikester - Carbon is a by product of unburnt fuel. as stated in the video a fuel additive was also used in this engine the fuel additive provided a more stitcheometric (complete) burn of the fuel that greatly reduces the amount of carbon left after the compression stroke of the engine. this engine has all the documentation of maintenance and the millage is acurate which leaves me to think you are not a mechanic nor a certified lubrication specialist

[06Duce49]

ikester7579 - engine sludge and varnish deposits are cause by oxidation and breakdown of poor quaolity unstable oils which is poorly refined and inadequatly treated with proper additives such as detergents and antioxedents. Schaeffers is a heavy detergent type oil that keeps insolouble contamination in dispersion so that insoluble matter won't emulsify and form sludge or varnish deposits. There is also a soluable moly that protects metal surfaces from varnish to adhere too.

[tarmac2001]

I'd seen a 4.6L for sale out of a police vic with over 400,000 miles. It wasn't being sold as a core for rebuilding either, but as a running engine to be placed into another Ford car or truck.

[Mr68charger440]

who says tht u have 2 have 37 yrs experince to tear an engine apart im 15 and i can tear apart a 350 and rebuild it no sweat

[PauliusBa]

u can hear whitney at the end! how will i know!!

[78SilverBronco]

check out my car domain site to see my 78 Bronco that had the motor torn down and rebuilt. 315k and the rotating assembly was in incredible shape. Rings, cylinders walls, everything. The only reason it had to be rebuilt was due to a cracked block from overheating.

[ikester7579]

I also noticed towards the end of the video, when they show the pistons. The piston held in he guys hand is much cleaner than every other piston laying on the table. The carbon left on top of the piston has nothing to do with the oil. But there was less carbon on that piston than I have ever seen on a high millege engine. Which leaves me to think the engine does not have the millege claimed.

[HarmonyStar22]

@ikester7579 actually it has been proven that the pistons on these high milage vehicles using schaeffers products do come out that clean your wrong sr

[ikester7579]

@HarmonyStar22

Are these tests done by independent labs like Lubrizol? You want to impress me. have you oil run through the tests Lubrizol would put them through. Google it. It's a one sided test when the same side films it, interviews it, does the tear down, etc... Now do you really think that adds up to non-bias results? Get lubrizol to due the tests, show the results, and also have an oil analysis done on the oil used in the tests. This won't happen for a reason. Which proves my point.

[ikester7579]

There is also what is alled chemical wear.. The cam shaft is what gets the worst of this because when te engine cools down. Parts in it sweat like a glass of ice tea, The acidity of the oil caused by unburnt fuel, mixed with the moisture from the sweating. Makes hydrochloric acid which raises the acidity of the oil. And because the cam shaft is exposed it's going to get some chemical erosion. Some oils it's worse than others. But zero erosion at 500,000 miles? Nothing stops chemical wear.

[ikester7579]

I hve taken 3 courses in lubrication and filtration. And have torn down a few engines. It does not matter what you use, there is always going to be a layer of varnish on the heads because the heads get real hot. Sludge is the oils inability to keep the dirt suspended so that the filter can filter it. So varnish is normal. But I could tell that the heads were wiped down and varnish removed. Which also means any sludge was removed as well. So it leaves the oil in question.

[HarmonyStar22]

@ikester7579 what about the fuel addivitve that cleans those pistons? wouldnt they then have no sludge.. my thoughts YES they would be clean

[ikester7579]

@HarmonyStar22

Then you don't know much about how fuel additives work. Only the top ring gets enough of the fuel additive to make any difference. The rings below get so little, the sludge build is more so than the additive. For the additive to get to the lower rings, the engine would have to have a bunch of blow by (worn out).

Example: A 1/10 micon filter cannot keep the pistons that clean. And that is small enough to remove moisture from the oil. A jet engine only requires a 7 micron filter.

[THEtechknight]

i have a 2.5L iron duke celebrity thats pushing over 300,000 miles

[lightningsmokerXx]

My grandad had a 89 Ford Taurus and it was the 3.0L had over 200,000km on it. Ran great......no oil usage and also passed the e-tests like a new car even when the oil was jet black.

[dexter2433]

i have torn down many and the only thing i have seen is if thy drive allot on the highway long trips they will stay very clean but if it is a in town driver were it is allot read light's all day long they will sludge up with any oil

and i know allot of drivers that get 300k to 500k out of a car with 3k to 5k oil change but the main thing is driving habit

use any good brand oil and change every 3k to 5k and you don,t treat like crap and it will last

[kwg2005]

looks like a SOHC to me. Anyway engine sure looks clean inside.

[carramrod423]

all the componets look like they have been cleaned

[btownmxer]

Nice Sales pitch. Change your oil every 1500 tp 3000 miles if you are worried about varnish in the engine. Thats why oil has detergents in it is to keep the contaminants suspended and keep the internals clean. No mystery here

[nascarpunk15]

your right, DOHC refers to 2 cams over 1 bank or Set of cylinders, This engine was a SOHC or sincle cam over a set a cyclinders, controlling both exhaust and intake valves on the same Cam shaft

[lithiumkc8]

Schaeffer's makes excellent products. UOA's back up Schaeffer's as well as many testimonials.

[s30zman]

i have a ranger with 258 k !!! ford rules just dont use a wax based oil.

[rudolphna54]

They give the oil too much credit. how about the fact that ford builds solid engines?

[shotgun8left]

that's probably the only thing ford has going for them.

[mickeymoose76]

Ford engines have always been noisy, rough piles of crap for me

[rudolphna54]

You must be very unlucky because its been the opposite for us. Especially our expedition, that is one of the smoothest running engines I've ever seen

[howtowakeakar]

My grandpa had a Tauras that he had to change the motor in every year or two, only Ford motors I've had bad experiences with. On the other hand, their build quality is utter shit. My uncle has a ranch in NM, and he bent driveshafts/axles often, just in normal use.

[rudolphna54]

Interesting. Our expedition has seen pretty heavy use (including towing a jeep 500 miles) and it is still in excellent condition. Interior quality is excellent, all interior and exterior panels fit perfectly, feel great, and the powertrain is nearly flawless (Ignition coils)

[GEARHEADGUY92]

yea he must treat his ford horribly

[HarmonyStar22]

@GEARHEADGUY92 just like any engine they can fail its a hit or miss type thing not to diss on ford but i have use many diffrent types of engines and ford has broke down on me just like a dodge weather treated poorly or great

[FixFalcon]

@mickeymoose76 Probably because you're a snot-nosed, dipshit that doesn't know how to maintain an engine?

[HarmonyStar22]

@rudolphna54 only when properly taken care of are they solid

[oney135]

go with Zmax it's damn good stuff it eats all the crud built up in the engine and cleans the valves and the block it works its been proven

[danielclack22]

No, it has not. Why do you think they had lawsuits filed against them???

[nitrofever]

I know schaeffer is great, however why did they pull this motor apart?

[HarmonyStar22]

@nitrofever cause they were given it to do so

[my93gsxr750]

then where'd that other cam come from in the background?? not saying youre wrong, maybe that isnt the same engine? idk whats going on

[jeremysgonenorth]

I can tell U this oil is better by far than royal purple and all teh other synthetics on the market. I can't comment on amsoil cause its to expensive for me, I got this stuff $5 qt and it has made my engines silent, Used to have lifter tick now gone with this stuff, Sounds like new and better MPG increased oil pressure, This is the only oil I will ever buy from here on out, And this is the oldest oil company in the world. I trust experience since 1839.

[durhamax]

what is oil pressure? oil pressure is resistance to flow. when its 20 below zero outside i would want the oil that flows the easiest and fastest to the top of the engine lubricating all the components. 75-90 percent of engine wear comes from initial startup? with AMSOIL having a slightly lower oil pressure reading this means that it is flowing alot easier. schaeffers is a good oil and if it wasnt for amsoil id be running schaeffers oil but amsoil quietted my lifters and im a believer!

[durhamax]

amsoil is more expensive eh? right now amsoil 5w30 is 8.90 per quart and a filter averages 16 dollars. so in a 6-quart chevy 5.7 liter thats $69.40 and that lasts 25,000 miles or one year....to me that sounds like the cheapest way to go to me

[lordbemylight]

Amsoil is not for me; SuperTech full synthetic, Carquest full synthetic, even Quaker State synthetics are good enough. But then again, I'll wait till later to use full synthetics, not much different than petroleum except longer oil change intervals. IMHO

[HarmonyStar22]

@jeremysgonenorth they did a test with amsoil to schaffers and other synthetics it was i think a 4 mile race and the only pistons that came out clean were schaeffers amsoil one was corroted

[ikester7579]

@HarmonyStar22

Send the test results to Amsoil. If they are not done by an independent testing facility that is willing to put their results in writing and stand behind them. Then it's considered slander of the companies name. And because of that. Amsoil can sue. That is why you use independent testing to prove your products. Anything else shows it's a shame. Because companies like Lubrizol have already set up the standards for this type of testing. And they don't fudge results.

[Zeroto90]

Thats not really that impressive, people dont realize how well built just about EVERY motor is these days, no one drives them long enough to find out how long that "engine" will turn and turn away, vehicles get sold too soon, and then the next owner treats it worse then the first, and then its sold again and so on, and eventually they get to the point to where people are trying to ruin them on purpose, we've seen the videos,

[NitroGadvRules]

@Zeroto90 yeah, but these engines are known for lasting longer than most. There harder to kill. The police likes this engine for a reason.

[giovanigta]

It all depends on how it was taken care of from day one you buy a car with 100,000 miles on and try good oil and expect longevity your an asshole all cabs and any highmile drivers get tons of miles just with useing conventional oil synthetic only makes it even better

[durhamax]

im not impressed whatsoever. they stated they changed the oil every 5-8,000 miles. amsoil has information on a mack engine that was torn down that had over 600,000 mies on the engine and 409,000 MILES ON THE SAME OIL! even with 409,000 on the same oil, all of the components were clean as a whistle and could be reassembled and back to excellent running condition on the old parts! AMSOIL has recommended 25,000 mile/ 1 year drain intervals since 1972! i'm still waiting on shaeffers to do it!

[jeremysgonenorth]

Diesel engines act like a detergent, Why do you think they have engine flushes for gas engines which is nothing more than diesel? Diesel internally run cleaner naturally.

[marek0086]

u have no idea what your talking about!

Diesel engines run much dirtier than gasoline engines!

Why do u think they have to use strong detergents in Diesel oils?!

[jeremysgonenorth]

Then why in the hell do they have engine flush bottles which is diesel? The shit U put in your engine and run 10 minutes before an oil change?

[LookItsRiceCake]

Because stupid people will buy anything if they think it will make their engine run longer.

[jayguy173]

They dont tell you redline uses group V base stocks wich is better then group IV base stocks paos in amsoil. Also the extra zinc used in amsoil is bad for catalytic converters. Its all about them base stocks.

[35Remmy]

My '88 Ranger 2.9L went 273,000 HARD miles on good 'ol Valvoline 10W30. Our 2000 Explorer 5.0 currently has 243,000 original miles on Valvoline 5W30. Considering synthetics like Schaeffers and Amsoil are 100X better than conventional oil, this is EASILY feasible. If you ever worked in a machine shop you'd know that FORD still has the best quality block of the Big 3. More nickel % than the other two which attributes to less wear.

[sdime406]

BULLSHIT!!!!

[jimmybrite]

I don't want to rain on their parade, but any good quality oil and a well maintained engine will show the SAME THING.

[Watcher3223]

True, but synthetic oil provides substantial overhead over conventional.

There's increased reserve alkalinity, which allows the oil to resist impurities that could make it corrosive, extending the change interval.

It's also more stable under a wider range of temperatures; it will flow when it's cold for less wear on cold starts and has a higher burning point when it gets real hot, resisting sludging. This allows the oil to better maintain its rated lubricity in extreme conditions.

[Watcher3223]

And the reason why the mechanic said "double overhead cams" may be because there are two cams when you count each one from both cylinder banks and he merely stated it as DOHC on that basis.

If this V8 were DOHC, there would be a total of four camshafts, two for each cylinder bank, with each cylinder having three or four valves.

But this engine is SOHC; there's only one camshaft per bank of cylinders and only two valves per cylinder.

[SRZsmack]

only if ford didnt suck... and kept that same 4.6 on all of their vehicles.

[rompn4x]

The 4.6 is starting to get the reputation of being a long lasting engine now that the miles are adding up on older 4.6's

[abzdefg321123]

EINNNN! wrong! DOHC motors have two cams per head not one... 4.6s are SOHC.....

[FixFalcon]

The 4.6L Cobra motor is DOHC, son.

[abzdefg321123]

Sorry "dad" but I highly doubt he'll be pulling a DOHC cobra motor from an E150; and yes I am aware that there are DOHC versions of the 4.6; but I fail to see how your comment relates to this video..

[Watcher3223]

And that relates to this video, how?

The engine in the video came from a Ford Econoline or a Club Wagon (the E-series are full-sized vans on a truck platform).

I don't believe Ford ever made a DOHC Cobra variant available for this vehicle, and for good reason; why would you want to?

What purpose would it serve to put a modified engine designed for speedy performance in a utility van/passenger bus where reliability and the use of regular fuel would be preferrable?

[jeremy34769]

I use RP but I am going to give this a try..Sound like good shit and since its america's oldest company I am sold!

[bradmann85]

an e150 is a van. that is very good for an engine near 500k

[MavDude]

At 03:23 he states it is a double over head cam. That would be incorrect. This engine is a single over head cam. If it were DOHC, it would have two cams per head, for a total of four cams. DOHC 4.6's cam in Mustang Cobra's and Lincolns and stuff like that, not vans.

Regardless, that is pretty impressive how clean that thing is.

[bradmann85]

he probably ment compared to an engine that has the cam in the center of the engine such as ive seen on cheavy engines.

[MavDude]

Ford, Chevy and Dodge have all built engines with the cam in the center of the block. This 4.6 is a modular engine, and not of the "double overhead cam" variety of modular engines.
