Stock 95 5.0 Compression Pressure??
Going to run compression check on my 5.0 w/90k miles. Books talk about all cylinder pressure readings being within 15-25% of each other as good. I want to know what the original pressure was in psi for a better assessment of contition because if all cylinders are 50-63 psi they are within 25% of each other so are good according to Chilton's compression check procedure. I think I read the pressure should be 135 psi but can't remember where or if these are even the right values. Will one of you tech spec guys out there help me, give me a number, give me a source document? Thanks in advance.
