Leakdown Test

Anybody ever have one done on their car?
Does anybody know what is acceptable and not acceptable per cylinder?

Anything greater than 8-10% is completely unacceptable, also there should be little to no deviation between the cylinders

Mike - Kapriyel did one on my 996GT3 last fall and I had less than 2 percent on a cold engine. Outstanding!
