[QUOTE="sonic blue l, post: 1071282, member: 5185"] Oh btw, I noticed what you said the service manager said about 10" of crankcase pressure. That is not normal, that is max spec. Normal would be about 3-5". Now of course there can be some variance in equipment, hence allowed readings up to 10". Just like somone posted compression readings over 400 psi, I don't remember ever seeing over 400 psi around here at around 2200 ft elevation. (Meaning elevation and equipment will affect what your truck may have vs what may have been mentioned on here). I will see around 380 psi on a good engine. [/QUOTE]
