Re: compression test

radiator cap too I believe. In case your're losing compression into the cooling system via headgasket for example.

That should do it,you can run the engine for a bit as to get a more realistic readings.

Good luck!

Re: compression test

Everything sounds good, but you may want to unplug the primary side of your coil - I generally do that when I'm doing comp test.
