Bmw N20 Valve Cover Leak. The valve cover is probably cracked not super common on N20s but it can happen if it has high miles the part circled is an oxygen sensor and cant leak oil but your whole valve cover is covered in oil so its either the cover itself or the oil cap. The valve cover is positioned on the crest of a BMWs engine and other vehicles.
Confirm It Right Now. I took it to the dealer which replaced the valve cover gasket. I have an N26 with 63000 miles and its leaking oil on the exhaust manifold.

Confirm It Right Now. Which is in many 2 3 5 and X Series start. I want to do the replacement myself but while looking for the best prices I find that the N26 specific valve cover is more expensive with less buying choices. The valve cover is a route that auto-mechanics use to test a variety of valves and rectify engine faults without utterly dismantling the complete engine.
