N63TU vent pipe hoses

image Ok I know I’ve talked about this before,,,,but we are seeing more of these as problems,,,,2014 N63tu the second generation twin turbo V8 engines,,,,there is oil on top of the engine,,,,and is coming from the cheap plastic vent pipes,,,,that break or crack due to the heat from the twin turbos.image Some time you don’t even see the stupid crack,,,,sometime you just see oil or yo hear a whilsting noise from the engine at idle,,,,this vent pipe can cause a lean mixture fault.image Here are the updated vent pipe,,,,they updated to new rubber hoses,,,,hopefully they last longer then the plastic ones,,,,,also they should crack like the plastic one,,,,have your dealer check these hose out next time your in for service.

    Very good to see that BMW changed the part. Do you know if the part was also reworked for the 2011 V8 Engine?

    Thank you!

    • Sorry to say no they didn’t,,,,that’s why BMW had that customer care package to replace those for the customer,,,,,but no they didn’t change the design or the bad plastic.

    Do you think this can be retrofitted into the n63? I had my vent pipes replaced TWICE in 6 months…

    • I already thought about that,,,,,sorry but no,,,,what happened did your crack again,,,,,they should not crack after 6 month,,,,,something must have caused it to cracked.

    Really scary as a current owner, it doesn’t really look so difficult to replace them,though. I have a CPO until next year but I believe CPO doesn’t cover any rubber or plastic parts. Thanks for posting!

    Is there anything else that should be checked, cleaned or replaced when these hoses fail? If they fail and the engine consumes a large quantity of oil thinking there might have other implications but have been told it should just “burn off”.

    Thank you for your post. It helped me get to the problem quickly. My 2013 F07 started developing a rough idle with the P0170 code this weekend. Heard a sound at idle I thought was accessory belt noise (its recently gotten cold outside), but it turns out that it was the connecting pipe completely broken in to two pieces just above the turbo’s (the plastic is so brittle, it crumbles under the slightest pressure), Parts are on order. Do you by chance have torque specs for the four bolts? I can’t find anything online. Thanks again
