Anyone knows where can i get refurbished, or used in good condition, vanos units?
I know that DrVanos sells them, but i would prefer a EU based company because of tax issues.

Vanos

Hello, I have an M5 E39, 1999 with 110,000 Km on the clock in as new and fully serviced condition, but very rattly Vanos. Do you do refurbished units as changeover at all, so no rattles?. It is showing no codes, so solonoids must be OK? Drives normally. Would love to cure the rattles. If so, please let me know including postage to Australia? Many thanks, John. [email protected].

Are you going to DIY the VANOS units off the engine? The rattling sound is nearly always due to lost tension of the diaphragm spring plates inside cam sprockets. The answer for the rattle issues is this great DIY: (By jamiepeers)

If you follow Jamie's DIY, it is rather easy to clean and replace the mechanical rubber/metal parts of the VANOS units.

How did your work on the VANOS change your engine except for the rattling?

Basically before this preventive repair I had normally functioning engine with new camshaft position sensors. There wasn't any fault codes. Also the cam timing was rather correct before the repair. At least I didn't notice any substantial performance increase. My car is only daily driver in the summer without any race track or dyno so probably I'm not the best person to judge. The performance addition (increased low rpm torque) migh be rather substantial if the cam timing is out before the procedure. The rattle at start-up and idle is almost gone. Even hood open I have to listen carefully to hear the slight residual rattle.

The VANOS unit rebuid itself doesn't do much to prevent rattle. It is just basic maintenance so that you know the 115bar hydraulic circuit is leak-free with fresh o-rings and has clean oil channels without any debris to provide best possible VANOS piston control. Also the new metallic circ clips and seals in the VANOS pump will stabilize the VANOS pump and bearings axially. All these items can show wear&tear and oil leaks due to years of use.

There has also been cases where some of the old cam sprocket bolts have loosened and destroyed the inner surface of the upper timing cover or even worse. This procedure is perfect time to replace the 8.8-rated old bolts with new 10.9-rated ones. They should be torqued to 10...12Nm region with loctite.

Thanks a lot. Great information. So the work is more like preventive maintenance rather than performance improvement.
My shop is recommending this to me and I am wondering if I should do it.

I think the 3 items related to VANOS pressure regulator valve are not listed in the S62 RealOEM part explosion charts. They are only listed in S54 (E46 M3) charts.

11361401971 x 1 (Filter - 115bar oil regulator valve)
11311318659 x 1 (O-ring - 115bar oil regulator valve)
11361403325 x 1 (O-ring - 115bar oil regulator valve)

S62-gurus have learnt from experience that they also fit for S62. I remember Raikku mentioned this in some thread in the past.

Research here indicates that the fine mesh filter each solenoids degrades quickly, then may clog up the solenoid.

It appears that people just remove any remaining mesh, can you remove the entire plastic ring with the mesh in or does it help create a seal?

Any point on replacing that plastic ring? I couldn't find a part number though...

Cheers,

Nakmuay
