A healthy non vortec engine should be in the 150 range.....Vortec engine 180. I would assume merc uses 100psi to defer warranty claims. Confirm with a leak down test.
I will check and run the tests again.

I also pulled the plenum off and sprayed down the intakes.
Star bolts on top yes, however the throttle cable is attached to the throttle body and will prevent you removing it easily. There are also sensor wires and a vac tube underneath it that may bind when removing it in one piece.Slight change of subject. I have the same engine, different positioning. My flame arrestors are blocked by the risers and there is no way to get them off without removing the exhaust hoses... and I'd rather not. I need to get into the intakes and spray also, and check the IAC - got a racing at idle issue.
How did the plenum come off, just the star bolts on the top? Can I remove it with the flame arrestor still connected?
