6.0 post egr delete and oil cooler issue
I have 2006 e450 that I had oil in the radiator reservoir and blowing heavy white smoke. So I ordered a delete and cooler from sinister. Put them on - truck fires up runs ok but left side manifold has alot of oil in it. And blowing lots of black smoke.
I took the uppipe or Y pipe off to verify oil was coming from left side only of manifold and it is - black smoke is left side only as well.
Anybody have a clue that won't make me go crazy?
