Hi all I'm working on an old d7e that suddenly was way over full on the dipstick one morning and determined it was fuel that was the culprit so we replaced the lift pump and seemed to be fixed the next time we went to run it same thing overfull.... soo called cat they sent a mech down and he said the new lift pump seals were junk from the time we put it on (brand new pump from cat classic) so he repaired it. Today we dropped the oil AGAIN because we had the problem fixed or so we thought... after the oil change it immediately began overfilling and fuel started running down the side of the block from the 3rd hole from the front between exhaust manifold and block... not cool at all so now I'm thinking injector problem?? Has anyone heard of this before? Any help would be awesome
