Tested the compression on all cylinders today. Man what a surprise. The resulst are as follows:
No. 1 - 93psi.
No. 2 - 91
No. 3 - 88
No. 4 - 95
No. 5 - 94
No. 6 - 91
Clymers states that compression should be 110-120psi, with a max variation of 15psi between cylinders.
Do you think with the numbers being as consistent as they are and not having any true symptoms of engine trouble that I might have faulty calibration on the guage?
How about a little chime in here. Do you guys think I have anything to worry about? It is a '94 (Merc. 225, 3.0L Carb.) without ever being overhauled. Do you think she's getting tired. Am I looking at major trouble in the near future or am I just getting paranoid.
In advance, I appreciate your input.
