Oil consumption 335d 2015 x5 f15
Ok I’m a dangerous weekend warrior / engineer but I’m stumped. This isn’t my first rodeo I’m old and looking for some input.
Replaced within 3,000 or less ago. -oil breather hose from vcg to turbo inlet (was ripped/melted) didn’t replace sensors. Just rubber hose. -valve cover and gasket. New OEM assembly. -oil cap new OEM -oil cap assembly that bolts to vcg. New OEM. -new turbo and hit a pothole. All done myself Before new turbo I could smell it burning oil after I hit a pothole on cold starts but now after turbo I can’t smell anything. And 0 leaks on or around engine/ car. Did the turbo a week ago and with all the tuning and wot pulls I already lost 1qt of oil and got a warning today. I have no idea what to try next besides valve stem seals. Could something else be causing some high crank case pressure? Or consumption. Any ideas / help / tests? Car runs and drives perfectly just eats oil somewhere. |

Have the same car/year but sorry no insight, but curious what your issue is. Good luck and hope you pin point the issue soon!

do you see smoke from exhaust? any signs of black smoke all the exhaust. my exhaust is impressively clear for a car with 130k.
I am actually experiencing coolant leakage ... internal leakage ... still investigating ... EGR (already replaced), oil cooler and head gasket (hopefully not). |
