Regarding a leak down test, you have to figure out a good way to lock the engine at top dead center. When you apply the 125 psi to the cylinder, unless you are at exactly TDC, The engine will want to rotate. In our cars you can probably lock it by putting a transmission in gear, and making sure the rear wheels can’t turn.

You will also want to mechanics stethoscope to listen at the intake runners, the crank case, or the exhaust - if you find that your engine leakage is above specification.

Starting to fart around with this again. I found this link on the web below which seems may be pretty accurate in finding TDC other than screwdriver method or other. Would just need a + - gauge. To turn the engine couldn't I just put it in gear and jack up the rear and turn the rear wheels by hand to rotate the engine? I don't prefer jacking just one side of the car because I have the fitted/flush windshield glued in and I have heard jacking one point of the car may have the potential of damaging the windshield or popping out. If I found TDC I suppose I could lower the car and take it out of gear and apply maybe 40 PSI or so from my compressor to cylinder 1 noted above and listen at the various potential leak points by ear or my stethoscope? Thinking 40 PSI to begin with may not rotate the engine but still allow me to listen.
