Expert Ears only please
Got a interesting question for those who like solving sound puzzles. I have had a squeal for WEEEEEEKKKSSS! I thought it was a intake manifold leak between it and the heads because i took it off before the noise was made but i have re sealed my manifold spacer 3 times and each using correct torque sequences but its still there.
Question for those. What does a head gasket leak sound like, would anything in the torque converter or transmission make squeal noises? The noise only happens when i decelerate or idle (sometimes). It used to be SO LOUD now its slightly noticeable. The noise is present when AC on or OFF but it most warm up before it can be present. Any ideas? hard to get a video due to too many noises happening in the engine along with exhaust sorry for long post

No expert, here....sounds like a belt to me...don't think a head gasket would make a squeal.....check your belt condition and tensioner, maybe squirt some belt dressing or wd30 on it, see if it goes away, at least temporarily...

I'd suggest making an attempt of capturing the audio

is the car running hot, is there oil in the water or water in the oil
these are usely indicaters of a blown head gasket They don't squeal, now you can find a intake link with a can of ether, old timers used wd40, just spray it around aroud where you think you have a leak Be very carefull these items are fammable But to me sounds like you got a tensior squealing or belt

What is WD30? I hope you didn't mean WD40, that will really make the belt slip.

Still not a good idea because you will get it all over all the pulleys and you will have to really do a job cleaning them off to get it to stop slipping... If you are putting anything on it use belt dressing only. Never anything to make it slip more.

lol...ok....it's just a quick way to see if the belt is what's squealing...and wd40 will make the squeal stop...It's not a permanent fix, and won't damage anything or make it slip long enough to be a problem...it dissipates pretty fast on it's own.... but if it does stop the squealing, then get a new belt and clean up any mess...no biggie..

Wonderfully Awful Idea

Check the catch can for leaks.

No, do not use WD40 on the belts! it will deteriate the belt. get you some belt dressing they sell it at autozone

how would i know if the catch can was leaking? i dont see any holes in the piping. seems to be coming from the backside of the engine underneath the IM.
when yall say the tension belt of whatever. where is that on a LLT motor

You say it's a squeal? That sounds like a belt pulley issue. However,tell us why you had the manifold off in the first place. if you purchased a manifold spacer my guess is that you have a part that is warping when it gets warmed up. the gaskets will compensate only a certain amount and the GM specs if you are following them for bolt tension really apply to original equipment I.e. With the metal and materials they were designed for. The torque is a consideration. if you purchased a spacer did it come with it's own bolts, are they made of the same type of steel as the original bolts or are they stainless. gaskets for the most part can not be reused, with any degree of confidence, once they are depressed you need a new set.
