Those are my compression test results... Some real strong numbers.

So seeing this... Would this lead me to a leaking valve cover gasket? As I'd assume that I would get low compression if I had a leaky valve seal, bad valve, headgasket, and the other obvious possible problems...

For those that don't know my problem.... Car was having misfries... played musical chairs, no dice. New plugs, no dice. And now here I am.

Any other possibilities other than valve cover gasket?

Default No... Didn't think it would be necessary with a solid compression test.

I always thought a bad valve (seal) would show low compression... But I could be totally wrong.

Default Meh. Won't show up on a leakdown either.

Valve seals are on the other side of the valve, so a cylinder leakdown won't show them.


He prolly has a bad ICM.
