valve cover gasket

  1. 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.

    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...
  5. 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...

    Took my 2004 325xi (80K miles) (first-owner) to trusty mechanic for a thumping noise in the front and to identify leaks under the car (started after I put two O-rings when replacing oil filter :shhh:). I did wait for a full week for the residual oil to finish dripping but finally gave in...
