Hi,
I just replaced the leaky head gasket on my 97 Neon. It only took me 20 hours. yuk.
2.0 (C) SOHC with new head bolts.
Anyway it started right up and ran fine, but under light acceleration (load) I get a quiet high pitched ringing noise. It occures at all rpms in any gear any speed. No noise under heavy load. It's not a squeek. More like a tuning fork??. Any thoughts.
Now for the bad news. Please don't laugh. I have one bolt left over. (:
It's a 9.6 black 1/4 inch about 1 inch long. 15mm I think, real flat with a built-in washer flange. I'ts just like the ones that hold the power steering resevoir to the head. It came off after the Intake manifold and before the motor mount, but I can't put my finger on it.
Thanks..
