Anybody know the correct procedure include motor temperture and steps to do a leak down test with Moroso Leak down tester?

Oh I did a search, found alittle about the procedure but the thread didn't say what temperture to do it at and do every cylinders have to be at TDC or make every pistons at the same height.

When your performing a leakdown test, you must have the cylinder which your testing at TDC. You have to ensure that the valves are closed when doing this test, otherwise your just shooting yourself in the foot.

And perform the test at operating temp...just as you would a compression check.
