Message: [QUOTE="powerstrokeboss, post: 1540478, member: 29448"] Got a 08 6.4 that I've noticed has some pretty good crank case pressure once warm. I pulled the motor to install studs and a single turbo, thinking I would have to replace a cracked cylinder as well. None of the cylinders are cracked, I've cleaned and thoroughly checked each one. The one thing I did notice was a decent lip at the top of each cylinder but after pulling one piston I noticed there wasn't any lip at the bottom of the cylinders. Also the truck has had *** and egr for all its 265000miles. Dont wanna have to bore it and get all new pistons but maybe I have to. I guess it's either blowby or valve seals, lmk if there is anyway of telling or if you have any advise. Thanks [/QUOTE]
