Pushing Oil Out top turbo......
Hey:
Havent been on here in awhile. Having some issues with my 2007 5.9. I rebuilt it this spring ..... since the rebuilt it has been pushing oil into the top turbo. There is an II 62 on top and a borg 74 on the btm. I believe the oil is backing up the drain tube, I have had 3 different turbos on it thinking that it is the turbos issue. There is less blow by at the oil fill now than there was before I rebuilt the motor. I have intentions to take it and get the blowby measured, just haven't had time yet.
I have 6000 miles on the motor so far. Have towed heavy with it for hours at a time. there is some blow by coming out the blow by tube but not excessive in my opinion. have pulled the top turbo and ran the motor, no oil coming from the head, and turbo drain takes oil that is pumped thru the pressure line for the turbo. The other notable thing is if the truck is idleing and u plug the engine vent it immediately pushs oil out the turbo drain. the atmosphere turbo leaks no oil ever to my knowledge. Is it possible I have excessive blowby still or I broke a ring assembling the engine or have I got 3 bad turbos from II (which I don't believe to be the case)
truck is an 07, 5.9. Motor has Mahle pistons and rings - 20 th over, Hamilton cam, exergy sac style injectors and 10mm stroker cp3.
thx in advance
