Valve cover gasket replacement Z4

Hi
My 2005 z4 2.5 is leaking oil. After some searching I determined that it's because of the valve cover gasket leaking. I smell burning oil in cabin too.
I did lots of search but cannot locate what is the part number for the OEM gasket.
I don't know if I should get OEM or get some other brand which is better?
Obviously OEM failed on just 70k.
Can someone please help and advise?

I'm also planing on doing the job myself. Is there any guide on how to do this on my z4.

They have the gasket (oem and aftermarket) I would go oem. The job is pretty straight forward I put silicone on both sides and let it sit over night before putting back into service. I would clean everything thoroughly prior to reinstallation and if the plugs haven't been done lately now's a good time.

The Is there any OEM part number for the gasket? The part number showing on the website is 11120030496 but it is showing up on all the aftermarket gaskets so I'm not sure if this is the OEM part number. Can someone help please

Bavarian Auto carries OEM parts. I don't know if the numbers will cross with other sites but I personally order from them often and if its says oem on the site then its oem.

This is one reason I don't like buying from Bavarian Auto. They don't tell you if the part is actual OE (BMW stamped parts) or OEM (non-BMW stamped parts) - so, you won't know what you may end up getting. For this exact reason, I like ECS tuning more as they will clearly states if it's OE or OEM.

OP, I would use the OE BMW gasket. It may not last as long as you would like it to be, but at least it seals properly. I just replaced the valve cover gasket on my M54 X5 with OE BMW gasket without issue. The aftermarket gasket on my S54 Z4MC, on the other hand, has a small leak right after installation - too lazy to swap it out now since my next valve adjustment is coming up in a few months or so - I will definitely go with an OE BMW gasket when the time comes on the next replacement!

You can go to realoem.com or bmwfans.info to look up the BMW OEM part numbers. Pelican Parts also offers both OEM and aftermarket and they indicate which on their web site. If you want a source closer to you in West Palm, BMW of South Atlanta sells over the internet at a significant discount to the regular over the counter dealer price. They'll a bit more expensive than some of the third part sources, but the shipping from GA to FL is usually much less than from CA (Pelican Parts) or NH (BavAuto).
