Oil Leak

I was changing plugs this weekend and found oil in those little divot things next to the plugs on cylinder 2-3-4, and there was oil on the ign coil of cylinder 2. Does anyone know where this oil is coming from? the car only has 28k on it.

-Its your valve cover gasket... I just did mine and I only have 35k. It is not too hard to do it yourself in my opinion. You do not have to replace the bolts as some of the DIY write-ups suggest and the gasket is only 30 or so dollars. It took me 4 hours to do but I also replaced my low pressure fuel sensor and sparkplugs at the same time. Good luck

who does your oil changes? I was thinking valve cover leak when I saw this as well in my engine, but turned out it was some of the oil i spilled by accident when filling the oil back up in a hurry during an oil change. The oil will run directly to those spots in the picture. Im not saying it can't be your vcg, but try cleaning it out and drive it for a while, it if returns then yes i would say it is most likely you inner portion of your vcggood luck

I thought the same thing when mine leaked so I cleaned all of the oil out and it came back with-in a week... There is a baffle/gasket around the oil fill cap that should prevent oil from going into the valve cover area but it could happen. Oil down in the sparkplug valley is almost always a VC gasket.

My plugs looked like that as well after i had the oil spill around the oil cap, the #2 plug is right in that area...remove, clean it and check afterwards...if it returns then atleast u know for sure before taking apart your vcg...my 2 cents

I had 77k on a VCG and oil started pilling up and eventually leaked in 2 coils causing rough idle and random reduced engine power on my 335i. Literally oil was filled in 2 of the spark plug wholes. Leaky VCG can cause some headaches for sure.

ive been having similiar symptoms, as well as a metal on metal grinding sound on start up. almost like when you turn the ignition of a car thats already on. I'm bringing the car in next week, I'll let the dealer figure it out.
