Compression Check help

[rho]

I am going to check out a used motor and have some basic questions. I've never done a compression check and need some noob advice.

Will the local Kragen / Autozone carry decent compression testing gauge?

What numbers should I expect from a semi new rebuild with 9.5 pistons and a relatively new rebuilt head?

And finally, what is the best way to test the compression.

Sorry for all the questions,

Thanks

You need a compression gauge it crews into the sparkplug hole. You should remove all plugs and turn the engine over with a well charged battery. I think with 9.5:1 you should be looking at low 200 psi. Where are you located I have a gauge and time in the morning if you need some help.

Thanks for the info. I'll probably check the motor next weekend... I'm in Alameda. If you are free I'll email you a few days before I go.

Thanks again,

Robert
