Here's the deal... I just did a t56 swap on my 98 that has an aluminum 5.3 engine in it. We used an old stock clutch first with the same results as now.

We replaced the clutch set, flywheel, pilot bearing, and throw out bearing. When it warms up after normal driving it squeals when I come off of power and let it idle to a stop. I can let it cool down for about 10 minutes and it's kinda quiet until I drive it again and warm it up. It sounds like the worst belt squeal you've ever heard and we can't get it to stop. The sound will not change pitches if I push the clutch in nor does it ever speed up. It just fades out. After it is warm you can rev it up to about 1500 and hear the banshee scream.

I know people are going to start saying it's the pilot bearing but it did it with the old used one that was in there and the new one.


I posted this in the Manual trans section but I am now worried it's internal engine problems. Can any one point me in the right direction?

You guys aren't going to believe this crap but it was the pcv valve.

Heh, that does seem unlikely, glad you found it!

Glad you found it... what did you see when you looked at it...?

I haven't taken the valve off yet, I just pulled the dip stick out a bit to relieve the pressure. My friend told me about it and he just hollowed out the pcv valve and put one of those auto zone ricer breathers on it. I'll be doing that this after noon after I replace my radiator that just split open yesterday. I swear, if it were raining vag, a big floppy dong would smack me right in the forehead.
