how would i get the air into the cylinder? I don't have an adaptor that would fit, besides, isnt that just the reverse way of testing the compression with a compression testor?

After spending hours on the phone I may have found an IP out of B.C. for $400 and with a 30 day warranty, and this is off a turbo car. so thats good

Basicly I am waiting for tomorrow to see what the compression test results bring.

I'm kinda hoping that the bang he said was mabey a backfire or something not serious? But I still have to keep the fact in the back of my mind that when I turned the engine over with the oil cap unlocked and sitting on the valve cover it kept wanting to blow the cap off, and did so twice, So it really is up to what the compression test reveils.

I know there is not supposed to be alot of blow-by when running, but what about when starting/cranking the engine over? Would a whole in the piston cause that blow-by or would it be a valve, or is it even normal for that much blow-by when cranking?
