[QUOTE="dfb, post: 133149, member: 11792"] It sounds like a piston/cylinder problem more than a valve issue, I am not a diesel expert by any means, I am just not following how a leaking valve would allow that pressure to end up in the crankcase...it could get into the cooling system for sure. A machine shop can absolutely check the head for proper valve sealing and the presence of any cracking. Perhaps some of the more experienced diesel guys can chime in on this thought since the head is already off. Can you put an equal amount of ATF on top of each piston to see if any drain faster than the others, say an inch or so. [/QUOTE]
