Hi all its been a while school has been nuts and made getting anything done nearly impossible. today I checked cylinder compression as my trucks been running a little rough with all the commuting I've been doing.
1) 80 psi
2)190 psi
3)130 psi
4)140 psi
obviously the head gasket is gone aroun cyl 1, but I'm curious why the pressure in cyl 2 would be so high? I expected since its a well worn engine (over 200k) that cyl pressures would fall 130 - 150 assuming everything was functioning. I actually expected closer to 130. Any ideas fellers?
