While browsing burgertuning.com to learn about different available mods, I happened upon this "BMW Oil Catch Can". The description reads:
http://burgertuning.com/BMW_335_oil_catch_can.html
"It's no secret that the BMW N54 motor suffers from serious oil control problems causing oil to blow through and coat the intercooler and charge piping, gunking up intake valves and the VANOS system, lowering the effective octane, and generally degrading engine performance. The higher your boost levels the more apparent these problems become."
There is a kit for the N55 as well.
Is anyone out there knowledgeable about this "oil blow through" issue and knows whether it might also apply to the F30 335i?
Thanks!
