show you if you have a bad head gasket. I was just wondering and didn't know the answer for sure. My guess would be yes it would show up. I am just doing a big maintence overhaul. My compression was 230 across the board. I was so happy about that

 

it could. leakdown would be better. just about everyone here will agree

 

i have been trying to find someone to do my leakdown test.

 

you can do it yourself.

 

I would rather have someone who knows what they are doing do it because they really knew what to look for. Something i might miss
