I'll try again. My '66 Sprite enigne is making a high pitched tinkling noise
on over run. It sounds a litle like engine ping, I can't hear it under
accelleration or at speed, probably because of the exhaust noise, but is easy
to hear after letting off the gas.
It's doesn't sound like small end or big end rod knock, is the same speed and
frequency as valve train noise. Can someone help me out on whether this
sounds like a bad Timing chain? or maybe a valve guide? Any other
suggestions? Thanks for the help.
