Hello guys I have a 2009 bmw 335i xdrive coupe,I have a oil leak in from right of engine n I can't seem to find where it's going from and it only happen under throttle,if the car sits n idle it won't leak oil,I've done oil filter housing gasket,front n rear main seal,valve gasket,oil pan gasket and it's still leaking any idea what could it be and why it only occur under throttle,only happens to leak when diving,it's not head gasket

the turbos?

try to clean everything up then put some dye into the oil, when it leaks again you can probably see where it started from with a uv light

And also I got the engine block cleaned and I added the dye it seem to be coming from the bloc close to the belt tensioner

Hope it’s not the head gasket.

I think there a crack close by where the tensioner pulley is not too sure I gotta inspect closely,hard to tell cause it only happen when the car is driving,when it sits idle it doesn't leak

My belt burst n destroyed my first crank seal so I had it repaired it guy didn't put the correct seal

Did they check if any pieces of belt went into the pan? i would probably just check on your next oil change
