Today I’m replacing the crank case ventilation (CCV) valve on my 2000 BMW 540i. BMW recommends removing the intake manifold to complete this job, but this would create more of a headache than it's worth. I'm going to show you how to replace the CCV while leaving the intake mounted to the engine. Here are a couple of the symptoms that pointed me to the CCV:
1) A stumbling, or rough, idle on cold mornings.
2) Loud whistling/screeching noise coming from the engine bay.
3) Suction at the oil cap. Cracking the oil cap open releases the vacuum and temporarily eliminates the whistling noise.
4) Blueish or white smoke coming from the exhaust.
If you’re experiencing similar symptoms, chances are your CCV has failed.
This repair is for a 2000 BMW 540i, which is fitted with the 4.4L V8 M62 Engine. BMW used this engine across a couple of different vehicles, including the 1998-2003 540i (E39), 1999-2001 740i (E38), and the 1999-2003 X5 (E53). There are even some non-BMW vehicles with this engine including the 2000-2004 Morgan Aero 8, and 2002-2005 Range Rover (L322). So this repair will be the same for all of the previously mentioned vehicles.
There are (7) T30 torx bolts that mount the CCV to the rear of the intake manifold. In addition, there are (4) hoses that mount to the external face of the CCV. One of these hoses is secured with a crimped hose clamp that must be cut off and replaced with a small hose clamp.
