    Looking to get some help and see if anyone has had some kind of leak like this before, not sure if it is common. I was driving and right as I parked I smelled burnt oil. I opened the engine bay and saw oil sprayed all over the engine bay. I guess the oil leaked on the belts and thus sprayed...

    I've got a notable amount of oil leaking on the driver's side. OFHG was replaced about 2 years ago by a reputable indy mechanic (I generally try to maintain the car myself, but I took it in because the bolts on the hydraulic tensioner sheared off and I was short on time). Given all the oil...

    Hello, So I bought a bmw 330i 2001, WBAAV53491FT02013, and it is awesome and I don't regret it knowing the oil leak now. I just wanted your help diagnosing what the problem is here. It looks like it is coming from the bottom part from the video of the BMW guy performing my recall. Thank you in...

    Looking to diagnose what the potential source of this oil leak is. Anyone have any ideas? First thought was the VANOS high pressure oil line, or the pressure accumulator but the spray is quite wide as far as the floor area. Could it be the boot on the steering rack? Let me know what y'all think.

    The forum posts I find on this topic are a decade old and none were ever really resolved in the thread. My Car: '04 325i Touring, 275k miles Car is sitting in garage waiting for a part to arrive. I got to looking at the front passenger side corner of head, which has been oily for years...

    I found that oil is leaking and dripping from the back of the oil pan and trans (points shown in picture). I would assume this would be from the oil pan gasket but the previous owner said it was recently replaced. Just wanted to know if anyone has any ideas of other places it could be leaking...

    Hi, so I bought a n46 like 1 month ago and did some service like ccv+hoses, ofhg, oil change, etc. since then I had low oil light about 3 times so I started daily checking oil level. Once i came home at night I checked the oil level and it was right in the middle. The next morning I rode about...

    Hey so today I decided to fix my oil leaks on my n46. Main one being oil filter housing. I changed the gasket and then rode the car. Opened the hood and I still see oil coming from there. Any help or explanations? 😃 sorry for my English

    I've owned my 330Ci vert for a year. The car has 96k miles on it. When I changed out the AC compressor, I noticed that I have an oil leak. There wasn't any oil on the ground because the splash shield was catching everything. There is weeping around the oil pan as well as lots of oil collected...

    I am well aware that these cars are notorious for oil leaks around the valve cover. The valve cover gasket was replaced about 20k miles ago by the previous owner (as I was told). I have recently noticed some oil leakage on one of the top valve cover bolts near the engine lift hook (images...

    Hey everyone, Have an issue with my 2004 330i that I'm hoping I can get some 'ideas' and things to check to find the cause. Read many of the older threads about oil level sensors leaking. The car has 154k miles and it does see track time and have been having it maintained by a local specialty...

    After removing my oil filter housing to repair a suspected leak, I noticed oil above the mounting surface. It appears to be coming from the head gasket. Before I dive into that big of a job, I’d like some input. The car runs fine other than the severe oil leak. The coolant and oil are not mixing.

    Hello guys, for the past week my e46 has been leaking oil from the front of the engine to the ground on the passenger side. Originally I had thought it was my valve cover gasket since it was a cheap rock auto one, so I ended up buying an OEM kit with new grommets and washers, I torqued it all...

    Hi, all. I've been tracking down an oil leak which I think is coming a lower CCV hose. (Right hand side of hose number 4 on this diagram.) Can any of you experts confirm I'm barking up the right tree? I had planned on installing the cold-weather CCV system before winter, but if it is in fact...

    How original, my 2005 330CI has an oil leak. Where could this be coming from. Looks to be gathering at this exhaust point. Looking from the top of the engine removing the plastic covers and looking around the valve cover gasket, there doesn't seem to be any signs of fresh oil.

    There's a good amount of oil residue on my power steering reservoir but I've ruled out the hoses as there is no oil on them and I can't see any cracks. There's also no oil on the top of the tank so I don't think it's the O-ring in the cap (I'm going to replace it anyway). All of the oil is on...

    I’m planning on replacing my oil pan gasket on the 330i 2003, I’ve heard you need to drop the subframe. If I’m going to replace my rack and pinion as well do I still need to drop the subframe?

    Hey guys, I was just driving to the store today and noticed some smoke coming from the engine bay, pulled over and traced it to under the intake manifold area. I figured just some oil leak from the valve cover gasket and didnt think too much of it. After coming out of the store, the car was...

    Hi all, first post here as a brand new poster (very exciting, i know). Been a fan of E46's for a while now and im finally looking to pull the trigger and pick one up. One particular car for sale at the moment caught my eye... A manual 325ci with just over 80k miles. The car is being sold rather...

    I recently purchased a 2005 330i (my first car) and am aware a few issues with it (such as a coolant leak, of course) as I took my mechanic with me and had him hook his scanner up to the car to check everything out. Now, neither the seller nor my mechanic mentioned anything regarding the...
