    Hello All, This is not my thing, - posting stuff. But I wanted to share some of my (torturous) experience with replacing a 'valve cover'. It started with the 'loud whistling sound'. This one coming from the port located at the crankcase diaphragm cover. Many of you already know that it's caused...

    I have an e46 320 and at the end of last summer my car started making a loud squealing/whistling noise on startup that gets less intense once the engine heats up but is still present at certain rpms. It is a lot louder around 2000rpm. I initially thought maybe one of the pulleys had gone bad but...

    Hello all, I have been chasing an intermittent check engine light on my 2009 X5 with the 4.8 that we recently picked up, it has 140k miles. I replaced the CCV valve diaphragms as they were pretty bad as you can see in the pictures attached. When replacing the one on the drivers side, I noticed...

    So I've removed all the nuts holding it to the engine and also the fuel rail, DISA valve (unnecessary, I know), Idle Control Valve, Throttle Body boot and that hidden nut on the bracket that's under the throttle body but there is still something that seems to be holding on to the manifold as it...

    Hi everyone, this is my first post, hope to be welcomed with my 02 530i 5 speed. About a month ago I did the CCV and the two hard coolant pipes under the manifold. After about 20 hours of work over 5 days I finally got the car started, and right away I noticed a coolant leak(hard coolant line...

    I was inspecting my X5 4.8i the other day and found the foam cover on the Crankcase Vent Valve was broken and had slipped up a bit to cover the vent. Would this be enough to create increased engine pressure? Would it be significant? I have circled the parts on the attachments. I appreciate the...

    Hey guys, I'm just about ready to pull all my hair out. I recently picked up a super clean 2003 540i M-Sport with 89,000 miles (Auto) and it was running a little rough. I replaced the coil packs, spark plugs, crankcase vent, valve cover gaskets, vanos seals, alternator and radiator and all was...

    2005 330xi w/220,000mi. Car is in perfect condition, so would like to repair if I can. Short story. Drove car to airport end of December - car was fine. Went to start car on return 5 days later (single digit temperatures for days), and as soon as car was started, it was producing EXCESSIVE...

    Hi everyone. After doing a lot of research into changing the CCV system to an oil catch can system, i cannot find which is the correct PCV valve i need to buy for my engine. I was originally told i needed to buy FRAM FV345 PCV valve, however, i just fitted that and took the car for a quick...
  10. E90/E91/E92/E93 (2006 - 2013)
    Hello, I recently bought a BMW 335d and after a drive one day I decided to check the oil level and noticed diesel exhaust fumes coming from the oil cap. (I became aware of the issue when the car was 100% stock) I'm confident that it isn't a blown head gasket because there are no bubbles in the...
  11. E60 / E61 (2004 - 2010)
    Hello everyone this is my first time posting but I'm a long time lurker. I've had an intermittent low oil pressure fault happening in my 2004 E60 M54 530I. The fault doesn't stay in the fault logs in iDrive but shows up there while driving if you have the fault tab open under the service...
  12. E39 (1997 - 2003)
    I recently purchased a 2001 BMW 540i with 171k and was aware of some problems but they have seemed to have been getting worse. Initially the car only smoked for a few seconds on start up, and you could see some minor smoking from the passenger side valve cover gasket. When i first checked the...

    I have a 2004 BMW 525i e60 with M54 motor. Bought from a co-worker. Has 170k miles. Symptoms has a strong vacuum suction when I remove the oil fill cap when the car is on, same with oil dip stick. Weh accelerates car flashes check engine and car turn off, I have to place in neutral then...
  14. X3 E83 (2004 - 2010)
    Hey all, first post here as you can see. Great place you guys got here! So my poor girl is sad with a P0012 light. Doing some research on here and elsewhere, I've done these steps to help alleviate it: Replaced the camshaft position sensor on the intake side, Changed the oil, Cleaned out the...
  15. E90/E91/E92/E93 (2006 - 2013)
    Trying to diagnose an o2 heater CEL. Replaced all 4 sensors 2 weeks ago. Started blowing my f4 fuse for the heaters, and I think the crank vent heater. Rather than rummage under the manifold I though, maybe I can isolate the ccv heater. Turned on the car, revved to 5000, fuse blew again. Is...
