OK, hostage to fortune time.

In another thread I said that hot compression tests are a waste of time, all you need is a cold dry test, a cold wet test (one squirt of lube oil from oil can prior to inserting compression test nozzle) and if you want to be anal a blow down test at two crank positions with a regulated 10 psi supply.

Hostage to fortune because matey has his cold dry numbers.

If he now does cold wet and publishes the numbers, and then warm (warm always dry, never wet) you'll see.....

Precisely how anyone hopes that a 45 psi disparity on two cylinders is going to go away on a hot engine test and give six near as dammit identical results is an exercise for the reader to speculate on.
