Chevy S-10 Valve noise
|
Sign In
|
|
I have an 1996 Chevy s-10 two wheel drive with an 2.2 engine, with only 50,000 miles on it. I think that the valves need to be adjusted, but I'm finding no info. on how to do it or if you can do it. I can't think that it would be an oil pump problem, but I will check that with an mechanical gauge. Would putting an engine scrub additive in it or using an thicker oil (30 w) instead of the 5w30 that it says to use, or is that not a good idea. Any help would be great !

I'm having excessive chattering noise that sounds to me that the valves are slapping around and need to be tightened, almost sounds like I have a diesel.

It could be a number of things but there is a TSB concerning the timing chain on that vehicle.
Here it is
File In Section: 6 - Engine
Bulletin No.: 87-61-21A
Date: April, 1998 Subject:
Timing Chain Noise Conditions (Replace Timing Chain) Models:
1993-96 Buick Century
1992-97 Chevrolet Beretta, Cavalier, Corsica
1993-96 Oldsmobile Cutlass Ciera
1995-97 Pontiac Sunfire
1994-97 Chevrolet and GMC S Models
with 2.2L Engine (VIN 4 - RPO LN2)
This bulletin is being revised to correct Parts Information. Please discard Corporate Bulletin 87-61-21 (Section 6 - Engine).
Condition
Some of the above noted vehicles may exhibit a clattering noise at idle speed originating from the timing chain and front cover area. Chain wear in excess of the maximum travel of the timing chain tensioner may create noise that may be objectionable to some customers.
Cause
Lack of regular maintenance, as referenced in the Owner's Manual and the resultant lack of lubrication and buildup of deposits inside the engine may accelerate wear of the timing chain. In addition, there is a small lubrication hole in the front oil passage plug that could become blocked with debris if proper engine maintenance is not followed.
Correction
If the owner of the vehicle indicates a noise concern, inspect the timing chain and tension In addition, confirm oil flow from the front oil passage plug and replace the timing chain, timing chain tensioner, and both the camshaft and the crankshaft sprocket if necessary to correct the noise.

Valves don't go out of adjustment on their own. Look elsewhere for your problem. If it is coming from the valves, it more likely an oil pressure issue.
