Use realoem.com to look up parts. I'm not totally sure what you're looking for... the oil filter gasket (housing cover? if that's what you want) uses a large rubber o-ring.

Are you looking for #10 or #4 in this pic?:

My Ride: 2004 BMW 325i [M54]
Hello all,

I am new to this forum, but I have used this thread as a reference to all of my recent repairs. GREAT THREAD, as it has already been determined!

I'm hoping someone could help me with my oil leak issue for my 2004 325i [M54 Engine]. I've basically gone down the list of common oil leak causes. And I must add that each of these repairs were in fact MUCH needed. Here is what I've replaced so far:

-Oil filter housing gasket
-VANOS Line w/ new washers
-Valve cover gasket
-Entire PCV breather system (oil separator & hoses) including all new gaskets/o-rings
-Power Steering reservoir w/ all new hoses & clamps
-All new Power Steering pressure hoses & return hoses

AND IT STILL LEAKS OIL
I've cleaned the underneath of the vehicle, drove it around town & returned to the garage and let it idle. As I let the car idle, I inspect from underneath where the oil could possibly be coming from, but I am unable to find any sign of oil running down the engine block. Although, as the car idles it will accumulate a small puddle of oil.

Any idea of what I should be looking at? Maybe some of the replacement parts aren't quite seated? Although I've seen no signs of oil coming from these replacement parts.

I'm certain that the drips are coming from the middle of the engine bay, more or less from underneath the intake manifold area.

Thanks in advance!

Kind regards,
Rob

Okay, so I finally broke down and took the car into the BMW dealer. Of course I was given this huge list of things that need replaced on the car, and was criticized on how I had replaced some of the other parts. (Go figure) I know I'm obviously not some BMW wizard, but I'm also not an uneducated hilljack thinking I'm working on some lawn mower. (Sorry for the brief rant)

ANYWAY, the parts that I've replaced have been done correctly and have no issues. The one helpful thing I was told at the dealership was that overtime the Valve Cover will actually warp. Often times, this is where people assume it is the valve cover gasket that is causing the issue. I wasn't exactly certain at first, but it seems to be an understandable cause. Has anyone else been told this?

My father is a mechanic of 40+ years; he told me that the valve cover will warp if it isn't properly bolted down. I'm not sure if this means all valve covers will warp over time (assuming you have all the nuts fastened)

When I first purchased the car , there were actually 2 missing valve cover nuts. I just recently bought new ones, so there are no missing nuts. I'm starting to think this might be a legitimate factor. I haven't gotten a chance to look towards the back of the valve cover for possible leaks, but I do know that there is no sign of leaks from the front & sides of the valve cover.

Thanks for the response!

+1. Of course.. this must be it. It is one of those things that eventually go bad in all E46's. And it is a massive pain to change too. Probably not for the home mechanic. I had it done rather than do it myself.

Hi all,

I have this thread bookmarked and refer to it often. I have a 'new' oil leak that is getting on the lower section of the exhaust and smoking off that I hope you can help me with.

I know I have a oil pan gasket leak, but I am maintaining it via the preventative "add oil monthly" approach because replacing the oil pan gasket on x-drive cars seems ridiculous.

Per Pelican:
"The oil pan on rear-wheel drive E46 models is very different from the all-wheel drive model. On the all-wheel drive E46, the front differential is bolted to the side of the oil pan, and the right side front drive axle goes through the oil pan. In order to remove the oil pan, it is necessary to dismantle the front subframe and suspension of the vehicle, remove the front drive axles and detach the front differential and right axle inner bearing pedestal from the oil pan."

I also had a VCG leak, but a couple months ago I replaced my valve cover gasket and that area is clean and leak free. All seems good there. *There is NO oil on the upper portion of the exhaust manifold or engine area above the manifold like shown in the pictures on the first page*

Somewhat recently I've started smelling burnt oil through the heater vents and generally around the car. I kept checking the VCG area, assuming it was coming from there, but that is clean and no oil is getting on the top side of the exhaust manifold.

Tonight I found that oil is coming out below the exhaust manifold and pooling in the very back passenger corner of the heat shielding below the exhaust port. Any idea where the source would be? No codes... actually the car is running really well other than the smell. I tried to get better pictures of the area, but it was dark and getting the camera to focus exactly where I wanted it to was a challenge. I will try to get better pics this week.

Any help is greatly appreciated. I love the resources on this site and use it religiously to keep my e46 running as well as possible.

Hi Josh, did you ever find the issue to the exhaust oil burn?

HELP! E46 Coolant leak

Can anyone identify this leak?! It's a 99 e46 underneath the car roughly in the centre just behind the oil pan. It seems to leak only when the car is off. It drips but quite significantly I have to top up on coolant roughly twice a week. I've noticed the heater isn't really working either?

Could be almost anything since the leaking oil will flow down hill and get blown to the back of the motor. VC gasket, VC warped, oil pan are likely suspects. The e46 318 is not common here in the US so I'm not sure what the configuration of your oil filter housing, vanos oil line or crankcase vent system is. Count me as one of the people with a warped VC. I didn't want to believe that so I replaced the gasket a couple of times to no avail until I bit the bullet and bought a new valve cover and voila, no more leak. The coolant leak is likely a separate issue.

Could be one of the heater hose connections at the fire wall, pull the cabin filter housing to check them.

It still is very likely the VCG. You can have a pinch or some other obstruction from when you installed the VCG. Or you can have a warped VC. I've seen both instances, sometimes combined. Sometimes you can have a leak at the rear corner which is extremely hard to detect, even if you run a finger or a cloth or a flash light around the perimeter. I would triple check this and use only Genuine BMW valve cover gaskets only--absolutely no exceptions--ever

You can also make sure any plugs, caps, etc are tight at the back. Pic for reference, courtesy from google/Pei330ci (he has great pics of the engine) looks like there's 3 caps (not sure if they're for anti-freeze or not but still check if you can) and a allen/torx head type screw plug. Worth checking out. Other than that not much back there that could cause a leak except VCG. preparation, cleaning, proper sealant application (assuming a straight VC and genuine BMW VCG)

Funny I see this pic, I was just telling a co-worker with an 08 that I wish I had just cherry picked the engine and tranny and did everything at once. May have took me more than a month, but it'd be worth it.

it's most likely leaking at the firewall. there is two hoses for the heater core. you need to take out the cabin filter and the compartment where the cabin filter sits in. you should change those hoses soon or it will bust and car will overheat and you will or may damage the head gasket.

you don't want that to happen.
