How to test valve seats properly: Did i mess it up?
So it was an absolute mission but i finally finished lapping all 24 valves in the N54 head and replacing the Valve Stem seals. I did the liquid test straight away but i was still concerned about the quality of seal on the valve. I certainly do not want to have to take the motor apart again for a mistake i can fix now. Anyway after a phone call i managed to get the proper tool for vacuum testing the intake and exhaust ports, like a shop used to test a professional valve job.... So this is it.
