Oil leak issue. I googled it already.
BMW 135 n54
Last summer, no oil issues.
This winter, i did some maintenance
-New VCG
-New injectors
-New external PVC set up
-Oil filter housings gaskets changed last summer
Now, the turbos were removed and the wastegate bushing was replaced. The chra was removed from the exhaust and intake housings. Not much if any shaft play (in/out)
All new Orings and gaskets on the turbo lines/return lines.
Now, the fun part. I took it out for a day to make sure everything was good. I smelt oil being burnt from the vents in the car.
I took it to the garage, saw some oil on the downpipes. Removed the down pipes, saw oil on the Vband and oil drain.
-Removed the drain and put another new gasket.
--Upon removal, there seemed to be a decent amount of oil coming out of the drain when i removed it from the block. Oil backing up? too much oil in the motor?
I took it out for 2 days, same smell came back. Back to the garage, same spot i see oil.
No oil on the top of the turbo
No oil from the valve cover gasket.
My only other thought, was oil leaking through the rear turbo seal. (no oil in either intake or exhaust housings)
If the turbo exhaust housing wasnt pushed 100% flush to the chra, but the vband still closed, would this cause the issue?
Do i need a new rear chra? I don't want to upgrade the stock turbos.
Pictures to come,
