Need Help
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

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
