Leak Down Procedure (Pic Heavy)

..............Hmmmmmmmmmmmmmmmmm.......... Now there's one I had not thought of..........

Might be better, though, to come up with a vacuum tester rather than high pressure.. Not too sure the intake gaskets would reliably hold 100 psi, and certainly not something like the "bottom pan" design of the magnums.

I was thinking in the 25psi range like the amount of a good turbo ?
