I'd be ok if it burns oil for 6 months untill ring seats but I can not deal with the oil getting everywhere under the truck, heck, im fine adding a gallon or two evwry 5 tho miles.
Did the guy you met also had oil dripping out of breather tube?
Oil dripping from breather tube on fresh rebuild.

Ok, to check air compressor you say to remove braided hose then what... Remove oil feed line and use shop air at the fitting where I disconnected braided hose and look for air out of feed tube from compressor?Last edited: Apr 18, 2022
Rideandrepair Thanks this. -
Im going crazy. -
The air compressor I have seen cause it to use oil by pushing it into the intake via the inlet line of the compressor. That’s easy to see as inside of inlet line will be oil soaked. I have also seen them push oil through the hot line into the tanks. I have not seen one pressure up the inside of the engine and push oil out. Not that I’ve seen everything by any means.
I have seen 2 turbos loose boost to the engine through the seal on cold side however they did not create a oil loss condition, loss of hp was the complaint. Not saying they cannot cause one to loose oil but it would be rare.Rideandrepair, LameMule, Big Road Skateboard and 1 other person Thank this. -
I thought if turbo goes bad it will push air inside the engine but I understand now it will only use oil by sending it to either intake manifold through suction hose which is dry, or send oil to the air tanks that I already opened the little drain valve and no sign of oil or even water, but if that was the case I would be seeing smoke out exhaust and theres none.
My turbo boost did improved after the inframe, I almost hit 30 psi, prior to that I only saw around 28.Rideandrepair Thanks this. -
You don’t always have smoke with oil consumption on a Diesel engine. Though you should see some in back of the turbo. If I understand what you have going on it’s pushing oil out the blow by tube......a bad hole or several bad holes doesn’t necessarily mean it’s burning it. Do you know if it has piston cooling nozzles or not? If not the odds of a bad hole and not burning oil get better.
