um, I know I'm going to get called some bad words cuz I'm going to say this, but I do it all the time on my cars. But I would try motor flush, if you don't change your oil (not saying you don't) it causes issues like this. Also I have had issues where if you use the same engine oil for a really long time, even if you change it, it starts to stick together even after changes. I do it to my cars every few oil changes just to keep the gunk for sticking together.
just by hearing the sound of the no one can predict the cause of knocking well its piking sound that's travel between the combustion chamber you should service your car in nearby service center.
the main causes of this problem are
high compression ratio
over heating of the piston block may be the lack of lubrication
there may the carbon formation in the fuel injector which get heated up and becomes the secondary source for preheating. ultimately cases the runaway knocking
Oh Yes the Amazing Knocking noise. I had the same problem with my G. I hate to say it but you have one or more spun rod barring. There are a few ways you are able to go about fixing the car, replace the spun barring (for temp fix) or build the bottom end (strong forged internals). Either way the motor is going to have to be ripped apart so if you have the extra cash build it.
@xFReSHeReST lmfao yes im serious maybe the knocking is coming from the fucking tire XD are you fucking serious? watch the video maybe you'll understand...
@Angelus12308 No doubt, compression ratio is not always the same, I'm referencing to the engine in this video and I'm talking about knock sensor not O2 sensor. I wasn't talking about fuel being burnt in two different places nor how much of it burns. You're going off topic. Keep your idea simple so the audience could understand.
@Angelus12308 compression ratio of a cylinder is always constant, I'm talking about air pressure (air being compresed by piston) in a cylinder not compression ratio. More air in the cylinder increases pressure which result in temperature increase which causes premature combustion and may result in detonation obviously the knock sensor should tell the ECU to inject more fuel but the fuel injector has its own limitation. Need i explain more? I really don't want to explain more.
@bulfric first change your oil and don't put in the cheap stuff. Then use higher octane gas...the cheap stuff is lean and leads to preignition easily. If the knock is still there check or replace your EGR valve. It controls the temp of the combustion chambers by recirculating spent exhaust gas back into the comb chamber effectively reducing the temperature. If that doesn't fix the problem retard the timing...
can anybody help me?I have dodge avenger 1996 and when I start it,it's all good,but about 3-5 minutes later it's start knocking like hell,and when I hit the gas it knocks even more and faster,,,,,what should I do???thank you
A OHC (over head cam) engine does not have lifters, I can't count the number of times people screw this up. Most engines these days are OHC since OHV technology is about as old as the hills and terrible for economy and making high RPM power. I'd say with 98% certainty that if it is not an American made engine it is OHC.
No, there are NO lifters and no "lash" in OHC engines. There are cams shafts, valves, keepers, and retainers. the cams slide against the retainers; thank you very much. when talking lifters and pushrods that is STRICTLY OHV engines.
correction, the cams do slide against the valve stems. as for OHV you have a central camshaft, followers, pushrods, rocker arms then your valve assembly which the valve, spring, keeper and retainer. In that case the tappets on the rocker arms push/slide against the valve stems. So in a OHV there are many moving parts that slide and push against each other which creates your valve lash. Which is just play/wiggle between the parts.
@OBCblackhawk That depends on the design. My OHC has the cam lobe operating on a lash pad which is on top of a rocker arm and the rocker arm is ontop of the valve stem. And it dose have lash
Check the oil level first, then try and find out from what section the noise is coming from. As for the VQ30DE I don't know much about it so some googling and/or asking around elsewhere might help. But If your engine sounds as bad as this you have a serious internal problem developing most likely. you can use a long screwdriver with the handle on your ear and the tip on the block to help locate the knocking sound. But the knock can come for a lot of things so the best bet is a shop
All Saturns made from 1991-2002 (S-series) used over-head cam engines... same with the 4.6L Ford engine (used in the Mustang GT, crown victoria, grand marquis, lincoln town car, some expeditions, etc).
i doubt it had anything to do with the brand of oil but rather low oil. these VQ35DE engines burn alot of oil I found, my altima was almost 1.8Quarts low on oil when I went to change it at 3k scary as hell. so in other words WATCH your oil levels CLOSELY. It only take 10sec of googling to find low oil horror stories with the VQ35DE engine, great engine otherwise.
ehh it isnt that bad, its a great engine. You can fix it by changing the valve cover that contains the PCV valve (right side). That fix will slow the oil burn issue in most cases for 20k mi unless you already seriously damaged something by running it low on oil. valve cover is like 120-140 bucks I think, plus you can take the time to do a tune up and inspect things while you got it apart.
forgot to mention if you get the valve cover it comes with a new PCV valve so you dont need to worry about that. You might also wanna make a oil catch can while you're at it?
Bullshit you loser i know soooo many american vehicles that knock. When you do regular maintence to infinity vehicles they generally last a long time.
@Deere842 Plastic? Every car the America "Big 3" makes are ALL plastic(Camaro, Mustang, Caddilac XLR, the list is too long). That's why they all went bankrupt and had to blow Uncle Sam for government aid, and they STILL shut down 60% off their dealerships. Domestic car suck, that's why no one buys them and they have zero re-sale value. Nice try though, but you're never winning this argument. Go enjoy your 30,000 mile warranty.
@amirecan I do agree with you on that one, All cars made these days are made very cheaply, I drive a 1978 dodge b200. The warranty may have expired already! I would not buy a modern car these days, I'll stick to my good old Cast Iron V8. If it makes you feel better about yourself, Concider this "argument" won. You have your opinions and I have mine.
@Deere842 You are correct. But you're part of the 1% club, meaning atmost maybe 1% of society would view cars as you do; "olds ones are better than new...i would not buy a modern car"..etc.( I actually agree with yo 100% on this, almost all new cars suck, older iron V8's do hold up MUCH better). I guess mass production and bottom-line, low-cost produstion has it's draw backs, haha, Domestic AND Foreign. Can we atleast agree that European cars are garbage? ;-)
@blargblarghonk After an engine fire, aluminum looks Salvador Dali-ish. International engine blocks i.e. 13 L I6 are a special iron alloy. The engines have a 1.4 million mi. TBO. I wonder how much aluminum was recovered from the Shuttle wreckage? Aluminum, as we know it will always let you down.
you should get that checked out, you stated you changed the oil but that only helps temporary, i see it all the time with people selling tuners (civics/integra's......) if engine starts to knock they put in a heaver oil and it severely lower's it for a while.. i may be wrong in your case but thats my 2 cents
yea the knocking was lowered and i also reset the ecu and the noise was gone...but i dont need to worry about that anymore because i just traded it in for an 09 g37XS last month...:)
Have you checked the computer for any emission sensor errors. A bad or clogged EGR valve or o2 sensors in certain types of fuel injection systems have been known to cause this.
@mrblockboii are you sure it's actually knocking, and that it isn't something like your valvetrain or possibly even injectors? I had an EP3 hatch, same engine obviously, and I heard it all the time, and you should ALWAYS use what Honda recommends, because these engines are machined to very tight tolerances, and need a thinner oil to get into all those tight spaces. I think you have nothing to worry about.
it makes very light knocking sound, and i can only hear it when the car is in neutral and idling. but otherwise when the car is running on the road everything looks and sounds fine as is.
im using 5w20 for now but i think i should move on to 5w30 or maybe 10w30 if i needed.
i will upload the vid of my car idling sooner and let you hear it.
Sounds like rod knock, spun a bearing most likely, I had a Mustang years ago that sounded the same way. I wouldn't run it too much like that if it ceases up it'll throw the rod. It is still fixable but it'll cost you alot. Good luck. Id have it towed to the shop for evaluation.
ALL engines have connecting rods, you know the cast or forged pieces of metal that connect the pistons to the crankshaft!! Just sharing a past experience. Thanks for your response, I prefer the power and sound of my Hemi over a smaller v-6.
dont read this, please,In 2000 a babysitter was caring for the children, she went to check the kids, they were safe and fine, as she came out she she saw a scary clown statue in the corner. She called the parents and said, "i didn't know you had a clown statue." they said we don't
The clown murdered her with a butcher knife
at 10:00 he will be under your bed or in the closet waiting to kill you. The only way to escape this is to post this on 11 videos
wow you think your pretty smart huh, you can adjust any valve by lapping it and refaceing it dumb ass, self adjusting or not. AND TIMING BELT OR CHAIN DOESN'T MEAN SHIT, MORON!!!!!
The rod won't likely go through the head. It would have to either take the piston with it or go through the piston. The when rods are thrown, they usually shoot through the bottom of the block.
please help me fix it. hahaha. maybe you should help urself and quit redlining it every time you touch the gas.theres no please help say a magic word. it needs repairs.
my engine knocking has disappeared...i change the weight of the engine oil to a 10w30 and poured in a quart of rislone's engine treatment and the knocking went away.
Judging by that air intake, I'd say that it developed that knock after some high RPM abuse. You're going to need either an engine rebuild or a new engine. Best of luck.
if i were u i would take it to infiniti but if not then see if you know a friend that works a any car dealership and ask him/her if a tech can look at it cause they might do it for free.
Aw man that sounds horrible!!! what did you do??? you gotta get that checked out.... best thing to do with those cars... dealer is best place to go... good luck bro!
The oil didn't fix it. What you actually did was just added more oil. Vq's burn a lot of oil. Keep a close eyeon your look oil level.

-tapping noise for a VQ35DE DOHC Engine, It could be
Valves need adustment
timing chain pulley bent or Tensioner worn
Harmonic Balancer (Crank Pully) loose on crank
Bent Cam Shaft
Perform a Compression test to check your valves.
As for any thing else you will have to take a Stephiscope locate the noise, and disassemble the engine and do a hard visual inspection.

Idiot. The valves are self adjusting.
gospeedracer1826 3 years ago
If it was a cracked manifold the noise would be alot louder then that.
What kind of fuck'in ASEs do you have??
Sign up for UTI Rookie, then call me when you overhaul and rebuild your first Nissan DOHC Engine.
AND THE VALVES DON'T ADJUST BECAUSE IT A TIMING CHAIN ENGINE, NOT A TIMING BELT!!!
Research and get your facts straght before commenting!

The rod won't likely go through the head. It would have to either take the piston with it or go through the piston. The when rods are thrown, they usually shoot through the bottom of the block.

what year of G35 you have?
is it a 05+ 6MT model?
if so you should bring it back to dealer for oil consumption test. Many 05+ 6MT out there now are having problems with engine oil consumption.

High rpm abuse, seems mine has the same issue, i have a 2k maxima with a 3.0, listen in my video.

Judging by that air intake, I'd say that it developed that knock after some high RPM abuse. You're going to need either an engine rebuild or a new engine. Best of luck.

if i were u i would take it to infiniti but if not then see if you know a friend that works a any car dealership and ask him/her if a tech can look at it cause they might do it for free.
