1995 Chrysler Cirrus 6 cyl Two Wheel Drive Automatic 102k miles
Things I have tried and found to be within specs.
1. Crankshaft and bearings
2. Flywheel/and cover
3. Oil screen.
4. Oil pressure
5. Oil level
Now after checking these things I cant seem to find the knock. I did pull one valve cover and started the engine to see if any lifters and or rockers were tapping but on that one side I did not hear anything I took the other side valve cover off moved rockers by hand looking for excesive clearence but did not find any. So now I am stummed even though I have not ruled out lifters as the possibility. How would I go about checking the rockers and lifters as possible culprits before I start aking the motor completly apart.
I would also like to rule out piston slap because Its not smoking in any way or burning oil.
Lastly I took a stethescope and listened all around the motor but again could not hear the tapping through the tool only without the tool but not sure where.
I can slightly here it the loudest under the car near the flywheel and cover openning.
and the tapping only happens when the car is idling after the engine has warmed up but when accelerating it goes away or when given gas at idle. Sometimes it goes away altogether before coming back.
ANy help would be great
have the same problem?
