Hello guys, 450 petrol (roadster) in deep winter (-20C) here. Couple days back I had an incident.. A minute after start, oil started spilling everywhere. I noticed that only at red light, after 3 kilometers. There was a lot of white smoke coming from all sides of the engine. Opened it up and wow, view is terrifying. So what happened: oil started spilling out from dipstick pipe, getting all around manifold and turbo = a lot of white smoke. Also it seems like oil did somehow get in to burning process, as there was a lot of while-bluish smoke coming from exhaust as well. I lost one liter of fresh oil that day. The engine was serviced recently (a month ago) and upper breather valve was replaced with generic one: original valve was failed (stuck partly open), I could not get whole pipe assembly in time. This is what I replaced it with: While waiting for a friend to tow it away, I immediately checked upper valve and it was operating fine (detach one end from throttle body, blow, then pull with mouth). So it seems to be OK. Couple hours later, when in garage, I checked lower breather pipe (part A1600180112): I found only very little ice in it, not nearly enough to clog up. I cleaned it anyway and assembled it all back... Today it happened again. Noticed it quicker, lost only 0.5 liter of oil... So now I'm lost. Oil is coming from dipstick, because there is pressure buildup and something is blocking it's way out. But why smoke from exhaust? Is oil getting sucked through upper breather valve? Can't really confirm it, but first observation is that the most of smoke from exhaust is only during negative boost pressure (when idling and upper breather valve is open). But the biggest question is: what I missed? Should I also remove and inspect TIK pipe? Or can it be caused somehow by upper breather valve? Something else?
