I have the same noise still, it's the vanos losing oil pressure from a bad seal. Beisan Systems - Procedures - M62TU Vanos Procedure
I'm going to post pictures of my guides that look new but broke because of defective material at 85k. I have an 2002.
Every timing chain guide repair also needs the vanos rebuilt no matter what. |
Mine is N62 and has the cam-spocket type vanos adjuster unit, which is actually a reliable unit and I have searched and have never heard of a failure. I guess your M62 vanos units are the same as the M54 6cyl engine - those that require a rebuild with new teflon sealing rings & o-rings.
