    Greetings! New here with a basic understanding of auto repair. That said, my local BMW dealership made some bonehead errors when performing a recall repair. My question is whether these specific errors caused more problems AND/OR could any of the additional parts needed to be removed and...

    Our 2011 128i started idling hard and squealing after driving about 20-30 miles. The shop told us we needed a new Pcv valve. About the same time the recall came out. BMW replaced the valve. We got 100 miles from Home and it started doing the same thing! Please advise. Thanks!

    I have white smoke that comes from my tail pipes after it sits at idle for a little while(ex. like at a drive-thru or red light). There isn't any visible oil leaking from anywhere that either I nor two other mechanics know of. Could it be the oil separator valve, pcv valve, head gaskets, etc? Is...

    My 328is currently has about 83k miles on it. When fixing an oil leak, I noticed some build-up in the engine compartment (see photos). My mechanic said this was due to a PCV, which is supposed to pull out excess water out of the engine compartment. I live in Minnesota and at the moment, is...

    Hey All... I have a 2003 X5 3.0 (M54 Engine).... Cold weather and my crankcase breather valve (PCV) froze up and caused my valve cover casket to blow. Well I ordered a new breather vavle (winter version - LOL) and I am looking at replacing this beast. My Bently manual has really nothing on...
  8. E36 M3 (1995-1999)
    So I recently found out my PCV Valve, Cyclone Separator,or Crank Case Ventilator. Whatever you want to call it started putting oil in my intake manifold. I took some pics the first time I took my intake out and posted them. I soon decided to just go ahead and do a DIY because I like doing stuff...
