  1. E46 - Smoke > P0335 Code

    General E46 Forum
    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...

  3. Mysterious Oil Issue

    General E46 Forum
    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...
  4. Oil leaking onto cat, and blowing through vents at idle.

    General E46 Forum
    I had this problem a few months back, and I assumed it was a valve cover gasket so I replaced that and the problem went away up until now. Not sure if the valve cover is leaking again, or if the oil is leaking from elsewhere. Any help would be greatly appreciated.
  5. Help with an oil leak

    Driveline, Engine & DME Tuning
    I was under my car checking the tie rods when I noticed some oil on the plastic skid plate and under the engine. It's a 2005 ZHP with 165k miles. I looked around the valve cover gasket and didn't notice any oil leaking there. The valve cover gasket was replaced about 65k miles ago and the oil...
  6. Is your high milage E46 caked in oil?

    General E46 Forum
    Don't worry. Mine was as well when I first got it 5 years ago. Since then, I've replaced every oil seal imaginable and have a squeaky clean engine. Not only is it much more enjoyable to work on, it greatly helps with PM as leaks can be more easily detected. With very little time and $$, you too...

  8. Possible causes for oil leaking/burning

    General E46 Forum
    Let me start by saying I'm not the most mechanically inclined BMW driver, but after 7 years of having other people work on my e30, I would like to start getting my hands dirty on my e46 touring. I bought the car with a sizable oil leak, but had the pan gasket replaced about 1k miles ago. (I...
  9. Is this normal after valve cover gasket change?

    General E46 Forum
    Just changed the valve cover gasket and 15 grommets on my e46. Previously, it smoked some and smelled like burning oil at idle. I put everything back together and took it around the neighborhood. Well it smelled like burning oil and about 5 minutes in, the yellow oil light came on. I immediately...
  10. p0130, and oil leaking onto O2 sensor connector

    General E46 Forum
    Hi, Can anybody tell me if oil leaking onto the 02 sensor connector block could cause a short-circuit? I was under the impression the connection was water-proof? I was expecting to find the connectors near the top of the engine, but there's nothing there, they are near the oil sump
  11. Replacing valve cover gasket - does vanos work make sense?

    General E46 Forum
    All, I replaced the oil filter housing (OFH) gasket on my 2003 325i Touring two weeks ago. The left side of the engine had all the typical OFH leak symptoms. I cleaned up the area as best it could. I knew, though, that wasn't the only oil leak... I occasionally get a whiff of "burned oil...

    ///M3 Forum
    Aloha All, Finally had some time to get under my new to me '02 M3 and take a look around. I've owned the car for almost a month now and was surprised at the oil consumption, thus far. I've put 600 miles +/- on her now and have had to add a little over a half quart of oil. I've read up on the...

    ///M3 Forum
    So, I'm pretty motor illiterate, but I can figure most things out, I picked up this m3 only has 103k miles on it, it was sitting all winter, so when I started driving it the burning smell it made I assumed was just weeds burning off the exhaust, other than that it was just fine, wake up in the...

    Hello, Can anyone offer some advice. I've got a 2002 325i saloon which is a eating oil for fun. Started misfiring the other night after I'd took her to 130mph. Upon inspection plug no 4 was oiled up. It's been a bit smokey for a while for awhile so knew oil seals where on the way out. I'm...
  18. M54 Valve cover leak diagnosis

    General E46 Forum
    Hi all, Did a search and couldn't find anything useful. I ordered a new VCG (Elring part 11129070990) for my dad's 2001 330cic, as the present one leaks. When I got to his place and looked through the records from his indy shop, it says the VCG was replaced in April 2012 and again in March...

    Hello all! I recently bought a 2003 M3. Everything was perfect until I noticed a little oil leak. Not exactly sure where its coming from (haven't been able to jack it up and crawl under there) but I did get my phone up under there and snap a few pictures: ^ a view of the little oil puddle and...
