squeak or chirp?

[funrider]

I posted before about a noise in my 87 venture, 38,000 miles, but would like to get a little more information if possible. I am new with the v4's, have only owned mine for about 3500 miles. It has a squeak or a chirp that is quite noticable at a idle but goes away or turns to a whine as soon as I bring the rpm's up to over 1000. The noise seems to be there with the clutch in or out, but does seem to change a little. I need to repair the clutch as it started to slip when not fully warmed up. Using a stethascope it sounds like the sound is coming form the back of the engine, loudest on the back valve cover or in the clutch area. I have all the body panels, bags, and the trunk off and have repaired all cracks in them so this would be the time to pull the engine if needed. Wonder if it could be the timing chain or a bad chain adjuster, and how would I check that? Also what is the chirp that is talked about? If needed I could try to get a sound track of the noise and post it.

All help is appreciated!!!

Hi,

 

at what RpM did you set Idle?

 

Have you had the Carbs balanced lately ?

 

'Noticeable' sounds not bad in my Ears in first Place.
