2006 325i Valve Cover Gasket Leaking?? Or Something Else??

Hi All,
I have a 2006 325i with 102,xxx miles. I purchased it back in February (For a great price) and knew it was leaking oil.
It appears that is coming from right around the valve cover gasket. I can see leakage all around it. My concern is that there is pooling around the engine and in the bottom tray of the car, and my garage is covered with a large spot of oil! Is this a possible cause of just a vcg or is there something else leaking too?
Anyways, I plan on doing the valve cover gasket myself. Can anyone give me a heads up on some pointers?
I figure for about $60 for the gasket and new bolts, and some time and swearing, it sure beats paying a dealer!

Any help is greatly appreciated!
Thanks,
Kevin

its a bit of a pain to get the valve cover off...be sure to buy a good torque wrench and understand torque angle...the bolts must be replaced as they are aluminum. typically it leaks due to the bolts breaking..

I have an 06 325i and I have had my valve cover gasket replaced. check your oil filter housing for any leaks. I had both leaking and alot of oil was leaking out and was gathering all around the bottom tray

I just did mine. Sorry didn't do a DIY, but it is a pain... If its your first time doing it give yourself atleast 4 hours if not more. I am sure we can do it around 3 hours now that we have done it. Getting the cover is a PITA! Everything has to be removed as BMW designed pretty much everything to get in the way!

Also, on mine the two front bolts were broken which was causing the leak.

bumping an old thread

I can't post a new one as I just jointed.
I just finished installing a new valve cover gasket on my 2006 and now the car turns over but will not start...


I don't know how to check fuel, spark ....
I've double checked all of the connections but realize it could be timing too
can anyone give me some advice on what to check first.

Check the wiring and connections again
I am pretty sure you forgot to connect something

Garage List
If you have an 06, the valve head bolts are known to break. I only noticed my broken head when I swapped my plugs. To properly see all the head bolts you need to remove the plastic cover, which involves removing the upper plastic section and wires (roughly 1 hour to DIY and install). I got it fixed under warranty but have heard trying to DIY it yourself isn't as straight forward as you would think (if that is worth anything...).

Check your head bolts and oil filter housing gasket first, see if oil is seeping from under the housing, so it would be hidden from sight but not touch.

Are you sure you hooked the ground up which goes to the valve cover?
