I never told him to spray his engine down why are you making shit up????????. Anybody who disagree with me about it making more sense for him to have a cleaner engine bay to diagnose new oil leakage is just oblivious at this point. Now you are saying it's better if he has a dirty engine bay....Brings me to my next point, from these pictures he posted of his dirty engine bay, it's impossible for you to sit there and say he doesn't have an oil leak...Furthermore you are asking for more pictures, and when he does send you more, you still won't be able to tell where the oil is coming from exactly. You can guess all you want to but it's really only one way to find out, you have to be there pretty much (the reason y'all advised a Indy/reason I advised diy). So what I did was encourage him to grab a rag, and clean up that dirt then see if any new dirt oil fluid (whatever you want to call it) came back. That's a lot more accurate than just making a educated guess based on a few pictures. For example, A ofh leak can look like a head gasket leak. But just because you see in pictures oil all along the head gasket, you are going to assume it's a hg leak. When in essence if you clean up the DIRTY path along hg and you clean DIRTY ofh and replace ofhg you would have successfully diagnosed "hg leak" just by cleaning and reassessing.

I can sit here and tell you I know how to work on cars, but it won't matter. So you got it, I can't work on them. Don't let me touch yours. I don't know what pontificating means. I'm sure you have never used it in a sentence in a real life conversation, but keep up the good work urkel

Just to give my input on pricing as my VCG is leaking (quart/liter every 1500 miles).
Active Autowerks quoted me $862 parts/labor with a 2 yr unlimited mileage warranty. A member on here who services my car quoted me $400. Local dealer quoted me $1,136 |

We all can come up with a million different scenarios of what's going on with the OP's engine, but based on the data provided we are highly confident the source of the oil is below the cylinder head, which leaves the next logical place being the oil pan gasket. Please stop replying to this thread as it is not helping the OP and is now only mere entertainment for the men in the room who actually know how to diagnose and repair automobiles. Peace out. |

Also updated the o-rings for the coolant reservoir cap and coolant bleeder valve, too. Worked like a charm. As was eluded earlier in the thread, I also have heard of changing/turning the reservoir's rubber mounts 180º so that the reservoir is level again. I never did that, but it seems totally plausible. |

Okay, I'm not really trying to beat a dead horse here, but I looked at the all the pics again (the power steering hose leak discussion still has me intrigued). I just noticed that the valve cover bolts are not blue-headed, which probably means that the valve cover gasket has already been done once. I few years ago I noticed BMW stopped painting the replacement aluminum screws (kits) with blue paint since I think by now it is well known that the aluminum screws used on the N52 that screw into the magnesium engine block (and pass through the magnesium valve cover on the '06 N52) need to be replaced. I did my VCG just about 12 months ago and the bolt kit (both BMW sourced) did not have painted screws. The bolt kit for the oil pan when I did the OPG was the same way, no blue paint.

I got to thinking about that too, but even though I've done the OFHG twice now, I'm pretty sure the three bolts are steel since they bolt into an aluminum head through an aluminum-body OFH (remember I'm a lonely old man - memory isn't perfect. Maybe I need a suppliment). I know I've not changed the bolts for mine either time, so IIRC they are steel and not marked blue. RealOEM doesn't show the bolts as being mandatory replacement. That said, the OP's engine has had no external oil leak ever IMO. There is no oil stain on the ledge of the aluminum head like I've seen on a several N52s.

As with the Z3, I think the only real issue with leaking oil into the spark plug well is it is a nuance most of anything and needs to be sucked out of the well prior to spark plug removal. Enough oil in the well would make for a burned oil smell. Would it ever cause a breakdown or fire? I doubt it.

I have the exact same leaks on my 2009 328i with 95000 Miles. I have a personal mechanic who works for BMW. He does all the work in his garage. He is charging $278 for the oil gasket and $475 for the valve cover gasket and spark plugs. My oil gauge drops about 1/4 of the way every 4-6 weeks and I just top it off. The main worry, which was mentioned earlier, is leaking from the oil gasket and popping off a belt. I'm also having my front pads, rotors and sensors done next visit for a very reasonable price. Hope this helps with pricing.

Definitely u guys saved me a couple of thousand bucks. Thanks to y'all and a special thanks to Efthreeoh for a detailed analysis. That particular BMW dealer lost a customer.
