Leak down tests pressure and time ?

[phillnjack]

When doing leak down tests on your engines what time periods are the tests done over ? 20 minutes ? 1/2 hour 1 hour ?

and at what pressures do you use for testing ( 2 strokes only please ).

what is considered an ok amount to leak down over such periods..

You adjust the supply air to read 100psi, look at the other gauge if it says 90 you have 10% leak down. No need for a set time if leaks it leaks 10% or more teardown time.
