Chevy 5.3lit Intake R&R HD

[elliottdl704]

Thanks for the great video. quick question, what is the fuel line tool called and where can you get it? Thanks again.

[5381986]

super awesome video you make it look way to easy....couple questions...any specail tools ie fuel line removal tool ect...also does napa sell the gasket you recommend and if no what exact gasket should i get and where could i get it...thanks again

[srmastertech]

@5381986

It does use a disconnect to on the fuel line. If you do not have one, you can remove the fuel rail from the manifold and lay off to the side. Napa does sell the gaskets. If there is any brand that is good, it is FelPro gaskets.

[JuliaDevan]

Great job on this video!!! Very informative.

[srmastertech]

@JuliaDevan

Thanks!

[bink637]

this is one of the best videos (of course, of this type) I have ever seen.Very clear, very concise, very informative. thanks so much



[srmastertech]

@bink637

Thanks for the great comments!

[rkeith8120]

Great video, Going to start my R&R in 11 minutes and 24 seconds. I love the sounds in the back ground. Must be near a drag strip. I swear I heard my Mach1 going down the track.

[srmastertech]

@rkeith8120

Thanks for the comment, and there was a Mach 1 in the mix!

[huskermanaz]

Doing this tomorrow. Thanks a ton, One question, What kind of gaskets did you use? I have the "upgraded" turqoise gaskets but some say to only use perma-dry from felpro? I am replacing the entire intake not just the gaskets.

[srmastertech]

@huskermanaz

I used Perma-dry FelPro gaskets with no flaws! Either gasket will work just as well in my opinion.

[TheChevyguy2002]

i own a 2002 chevy 2500hd with a 6.0L. my knock sensors need to be changed and i am just wondering if the 5.3 intake is the same as the 6.0's?

[srmastertech]

@TheChevyguy2002

Both engine are basically the exactly the same, so the procedure should very close. Some vacuum lines may differ from the video though.

[machster69]

@srmastertech

Oh, i face booked u some more detail on my leak... Im stressed about this repair :/

[machster69]

@srmastertech

Is there is there a sure way to tell an intake from head gasket leak? Or warped head?

[ROTCbrony]

@machster69 Vortecs have a dry intake manifold, so that's not your problem. Sounds to me like a head gasket or (God forbid) a cracked block. In either case, that's something I would leave to the pros. Best of luck to ya though.

[machster69]

And i jus read u said something about piting around the jackets, what if i got that? How to fix it?

[machster69]

Soo love this cideo! I gotta 99 z71, got coolant into the oil... I was told to change this... Is that right?

[dragonkev23]

THANKS FOR THIS AWESOME VIDEO I HAVE TO TAKE THE MANIFOLD A PART I HAVE A 171 CODE AND 174 CODE AND THEY SAID IT COULD BE THE GASKETS SO WILL SEE WHAT HAPPEN THANKS AGAIN

[srmastertech]

@dragonkev23

You will be doing exactly as I did in this video! Good luck and have fun!

[haterade8]

Great video im replacing my knock sensors on my 06 silverado here pretty soon anything I need to look out for?

[srmastertech]

@haterade8

Thanks for the comment. Hopefully this video will help with your repair. My best recommendation is to inspect the intake sealing surfaces. I have seen some pitting around the coolant jackets that can cause coolant leaks.

[tgerbec]

were the gaskets bad from the dex cool coolant destroying the gaskets?

[srmastertech]

@tgerbec

The intake gaskets were leaking at the intake passage causing a lean engine condition. The coolant showed no wear on the gaskets or leaking.

[tpi350n1]

Awesome video. I need to replace my knock sensors on my truck and its kind of nice to see how its done before I dive in.

[srmastertech]

@tpi350n1

Thanks for the great comment! Have fun!

[srmastertech]

@TobeNuts4U

I appreciate your great comment! Since I can't be there to work on your engine, with this video, you know what to expect if I did!

[777bowtie]

You do great work. From the doing the job to to the house keeping. Very professional. Thanks for the helpfull videos and I am now a subsciber to your channel.

[srmastertech]

@777bowtie

Thanks for the great comment! It's all about the pride I have in my work!

[deepsouthboggers]

Have you ever came across a knock sensor so corroded it came apart trying to remove it leaving the stud stuck in the head?

[srmastertech]

@deepsouthboggers

I have seen this happen before and there is no easy fix other than drilling out the broken section left in the engine and tapping the threads. I would also add anti seize to the threads. Once you get that out and the new sensor installed, use silicone sealer on the boot to prevent any water from entering the cavity and causing the same problem again.

[bmxman242]

you should do a tutorial on intake swaps for the 5.3 lm7!

I'm planning on using the Trailblazer ss intake or the newer nnbs 07+ intakes with a conversion plate for the cable Throttle body

[srmastertech]

@bmxman242

If I get that job, I will record it!

[vcalisto1776]

Thanks for this video it helped big time.Another peice of advice if u replace the knock sensors put some rtv silicone around those rubber plugs to keep the water out of the cavity and rusting out your knock sensors.

[srmastertech]

@vcalisto1776

Great point and thanks for adding!

[daytonasunset]

Mine loses coolant aswell, but it seems to get mixed with the oil, could that also be due to de intake gasket, or head gasket like usual...?

(The car has 135000miles)

Thanks for the vid. anyway!

[srmastertech]

@daytonasunset I suspect with coolant in the crankcase, it will be your head gaskets. A coolant leak at the intake would leak externally onto the ground or leak intake an intake passage and be burned through a cylinder.

[djp622]

@daytonasunset I kno those are the symptons of the castech head issue that these 5.3s are known for. A "very small %" of 5.3s came with 706 castech heads that cracked easily. The logo is inside the valve cover. If your under warranty still i kno several people whove had the dealership cover the expense of new heads. Big mistake by chevy.

[djp622]

Great Vid. about to do this on my silverado. One quick question. I kno online it says there is also a chance that these plastic manifolds tend to warp. So its either a $100 on a gasket set or $300+ on new intake manifold etc...whats the best way to tell whether or not your intake manifold has to be replaced due to warping?

[srmastertech]

@djp622

The best way to test flatness is with a straight edge. Once you remove the manifold, and place the new gaskets on the intake, you can place the intake with the gaskets installed and place on engine. Is should fit square where there is no wobble feel.

[sofujun]

would a bad gasket cause loss of coolant? I have a 2001 tahoe and i have to fill up on coolant once a month, cant seem to find the leak. What would be symptoms of a bad gasket?

[srmastertech]

@sofujun

A leaking head gasket can use coolant with no visible leaks. The amount is small enough that you may not see any smoke out the tailpipe. There do make a combustion leak tester that will test the amount of hydrocarbons in the coolant. Symptoms could be overheating, runs rough on cold start up, smoke from tailpipe and your loss of coolant.

[sofujun]

@srmastertech this might a stupid question is the intake gasket the head gasket?

[srmastertech]

@sofujun

Intake gasket and head gasket are 2 different gaskets. The head gasket seals the head to the engine block. The intake gasket seals the intake manifold to the cylinder heads.

[mhix102]

Thank you so much for this video. It took me about 4 hours in all to do but you saved me a good amount of money. Best of all my check engine light is off and the truck is idling perfect now.

[srmastertech]

@mhix102

It's great to hear the video helped. Saving money these days is important!

[sofujun]

Nice Job!

[srmastertech]

@sofujun

Thanks!!!

[srmastertech]

@bp257

Sorry to hear about your trouble with the knock sensor. Once water gets into the cavity, rust occurs and that's something you never know about until you get into it! Glad the video did help!

[huerod69]

Had to replace the knock sensor because of check engine light, and yes the one in the back had water and corrosion buildup ,after completing this job the light turned off and it pass inspection (Dealer wanted $500.00 to repair it!)

Thanks again for this very detailed video. I saved a lot of money!!!

[srmastertech]

@huerod69

Great to hear the video was of some help! Congrats on the savings!

[styles727]

Thank You this video helped allot!

[srmastertech]

@styles727

Great to hear, and your welcome!

[huffmanns]

Thanks for the video. I replaced my knock sensors in my 2003 Avalanche in about an hour and a half thanks to your vid.

[srmastertech]

@huffmanns

Great job! Glad to be of some assistance!

[1355550]

Good vid. have an 02 5.3 I have to replace the knock sensors on.

Is there a way to detach the fuel lines without havig to buy a special tool? Best method? thanks

[srmastertech]

@1355550

Without the special tool it difficult. I have used a small pick and it spent more time than its worth. Go to your local parts store and get the tool. It's worth it!

[ONENITO18Z]

Great video

[srmastertech]

@ONENITO18Z

Thanks !!!!

[jboydmv90]

Very efficient good work! I could use a guy like you in my shop

[srmastertech]

@jboydmv90

Thanks for the great comment! I really apreciate it!! Where's your shop at? I've had offers from Calif to Houston and even in Key West! I'm always interisted in offers!

[jboydmv90]

@srmastertech In New Hampshire

[srmastertech]

@jboydmv90

Thats a bit more east that I would like to go, but I apreciate it!!! You welcome to follow my work on Facebook as Senior Master Technician!

[Fortburb]

Great Video. Question. My problem is a coolant leak and i'm getting mixed information on whether or not coolant can leak through the manifold. (i'm losing coolant but can figure out where its going and i have the 5.3L). Does this manifold carry any coolant?

[srmastertech]

@Fortburb

Thanks for the comment! Coolant does run through the front side of the manifold. On the rear, the intake just blocks the coolant passage. If you have coolant leaking into the crankcase, the intake is where I would look first. Once the manifold is removed, you may see a clean area from where the coolant was leaking from.

[grtextube37]

Thanks for video. It was helpful; however, I question the details of disconnecting the fuel lines and the throttle cables as well as their re-installation. Any thing to avoid for those steps?

[srmastertech]

@grtextube37 Thanks for leaving your question! The throttle cables are simple to remove and install. The connection to the bracket is such that each cable can only fit into its own place and unable to fit is crossed. The simpleist way is to just leave the cables on the bracket as shown in the video. Just place the cables with brack out of your way during the reapir. The fuel lines are just as simple. They use quick connect fittings and can only fit one way. I hope this helps!

[Saylthecell]

thanks this video is awesome. going to be replacing my knock sensors now

[srmastertech]

@Saylthecell

Thats great to hear. I'm glad this video has helped!!!!!!

[jesseadkins187]

very very helpful! thumbs up from me

[srmastertech]

@jesseadkins187

Thanks Jesse!!!!!!

[bhallz71]

very informative video.  I have a bad knock sensor on my 2003 5.3 Chevy so I watched this to learn about taking the intake off. I hope it's not too hard when i go to do it myself

[srmastertech]

@bhallz71

Thanks for the great comment! I am sure that you will be able to replace your knock sensor with no problems. Just follow the direction in the video and it will turn out just fine!

[Fortburb]

@srmastertech Great Video. Question. My problem is a coolant leak and i'm getting mixed information on whether or not coolant can leak through the manifold. (i'm losing coolant but can figure out where its going and i have the 5.3L). Does this manifold carry any coolant?

[johnhasleftthebuildi]

Great video. Thanks for taking the time to create this very detailed process. How did you know the inner plenum gaskets were still good. I have a 2005 Silverado with the 5.3 and it makes a slight whistling sound when you hit the gas but it seems to run good and idle well. Thanks again.

[srmastertech]

@johnhasleftthebuildi

Thanks for the great comment! With the plastic intakes these days, it may sound like a vacuum leak and not have one at all. An intake leak will cause idle symptoms and if you have no DTC's and idle quality is good, your engine is running fine. I found the intake leak by watching live O2 sensor data. When spraying B-12 Carb cleaner on the intake gaskets, O2 sensor would read instantly rich indicating a leak.

[johnhasleftthebuildi]

@srmastertech Thanks for the reply it saved me the time and expense of doing the job. Your forum here is a great thing. I have just recently found B-12 Carb cleaner and there is no equal.

Thanks again, John

[srmastertech]

@johnhasleftthebuildi

Your welcome Jonh< glad it worked in your favor!

[metalxesp]

cool video, like the instructions

[srmastertech]

@metalxesp

Thank you, theres more to come!

[flipr7]

Most detailed and informative video Ive seen. Now if you could do another on a E350 with the 6.0 deleting the egr cooler. The little rubber hose between the egr and oil cooler is leaking the old red hose. I monitored with an sct and the oil and coolant temps were spot on. Any suggestions would be appreciated, from what ive seen of your abilities I can most definately trust your knowledge Thankyou

[srmastertech]

@flipr7

Thanks for the great comment. The next 6.0lit I repair for that concern, I will record. To replace that hose, you dont need to remove the turbo, just the water outlet cap from the oil cooler. The hose is avilable for replacement.

[JUDGERAMBO]

Did you smoke test the intake to find the intake manifold leak?

[srmastertech]

@JUDGERAMBO

I found by watching live data from O2 sensors. By spraying at the intake gaskets with a carb cleaner spray (brake clean works also), the engine rpm rose and the O2 sensor read rich indicating a vac leak.

[nflfreak4341]

how did you secure the gaskets to the lower manifold? copper spray or what?

[srmastertech]

@nflfreak4341

The intake gaskets are plastic with an embeded seal on the intake passages. The gasket secures to the intake with clips built into the gasket.

[nflfreak4341]

@srmastertech crap i forgot bout that... its set up the same way on a Chevy 3.1.... was a nice design to rebuild the top end...

[MikesFitnessGoals]

Really like watching your methods Rusty. Thanks for all the detail and description. I learn a lot for all your videos - especially like this one with commentary.

[srmastertech]

@MikesFitnessGoals

Thanks Mike!

That torque wrench isn't the new angle snap-on one is it? Also I liked the addition of the commentary

[srmastertech]

@subiekid110

Yes it is. It has inch lbs, ft lbs and in degrees!

[VicGord]

Great Video Rusty enjoyed the commentary thanks for that info
