Vanos solenoid seals Dr. Vanos vs OEM replacement?

I've been looking around for the advantages of the Dr. Vanos over the OEM replacements and there is no comparisons except for a member pointing out that the OEM rings have a bevel to them and are not O rings like the ones included in the Dr. Vanos kit. I haven't been able to find the part numbers for the "o rings"/gaskets, so that means no price reference either. Any info would be appreciated.

I'm interested to know as well because recently in Peter's engine build thread there is discussion that the Dr.Vanos kits cause a lot of issues. It sounds like OEM is the way to go.

Would recommend OEM. Have been spending a lot of time on similar threads since my M5 has recently developed "oil reflux" in the plenum and intake plumbing. Saw a number of recos for OEM only and at least one instance where the viton o-rings from Dr. Vanos failed within a year.

OEM is way cheaper,has the correct design of the O-rings and also lasts quite long..

Thanks for the diagram.

vantaam5, didn't you mention in another thread the other day that the OEM replacements now are made of better material and less likely to fail the way the originals did, especially for pre-facelift cars?

"I look at it like this. Owning an M5 is kind of like dating a slamming hot big-t...ed blonde, who is a pain in the *****, drains your cash, but screws like there's no tomorrow. Owning a Honda Civic or the like, is akin to dating a girl who is fat, ugly, smells a bit where she shouldn't, is a cheap date and doesn't screw at all (you don't mind). So yeah, I'll take the blonde." (Courtsey of Jetpilot718)

klunk, if it helps, this site has some VANOS info, in terms of what might be needed for a recon.

Mr Vanos - Bmw Vanos Repair Specialists - E39 M5 S62 5.0 Vanos

There's also plenty of info in the DIY section and just google 'vanos E39 M5' to bring up up lots of info.

From what I've found, it's either leaking seals which is fairly simple, or an actual failing/broken component (solenoids etc.) which affects the VANOS system.
