Default SMOKING OUT OF OIL CAP - 02-13-2018, 06:54 PM

Guys I need help, my 335i has already gone they a pair of new bmw turbos trying to chase this. I replaced the turbos and my car is still smoking out the exhaust. And this is what I feel is the issue. Any help would be much appreciated.

Did you check valve stems seals? If they're leaking could be the cause.

First things first.....any codes?

Now.....

When was your pcv changed?
When was your last walnut blasting service?
Any oil in the coolant or vise versa?

My guess is pcv or valve cover. I would also recommend a low side external pcv. You can get this at rbturbo.com

May want to do a compression and/or leak down test to confirm the engine is healthy.


See www.rbturbo.com for N54 Twin Turbo Bolt-On upgrades, or contact directly 314-630-8950 rob.rbturbo@gmail.com for a price quote.

Can something like this be caused by clogged up VC internally or maybe the block itself, passages to the VC/PcV?

Are there oil in your plugs?
