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.

Thanks for the diagram.

assuming the mechanical parts were in serviceable condition, what parts from that diagram are recommended for a vanos rebuild ?

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?

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.

I was not the one who said that,but remember the post.

Also it is not confirmed that this is true!
Did lots of research regarding that information...

Anyway,the OEM parts are good enough to last a few years....

</td></tr></tbody></table>
</td></tr></tbody></table>I would also replace no7 when pulling the solenoids,because the gasket usually breaks.But is only a dust seal,anyway.

If the full unit is pulled,9,10,11,12,13,14,16 and 17 need to be replaced.

The locking ring 10 was changed to a different design a few years ago.See pic below.
This is from a member's car,we dropped the lower oil pan to helicoil the drain plug thread and found pieces of washer no9 in there(as you can see in the pic,the washer has only left half of it original size,the rest went through the timing chain into the oil pan)
The original locking rings press the washer only on 3 positions to the oil pump.

All the Vanos units I did rebuild so far(and this was quite a few),had different stages of wear on this washer.

In which case, apologies, didn't mean to misquote...

Would it be fair to say that if you wanted to do a minor 'tune-up' on this you'd just need a bunch of 3's, 4's, and a few 7's? I don't have the skills or tools to do a full rebuild, but I wouldn't mind a solenoid 'fix.'

I have about 97k now on my '03...no symptoms, but if some 3's, 4's, and 7's would perk the car up I'd be glad to do it. Aren't there little oil filters on the solenoids people generally remove as well?

And if going OEM where are these parts being purchased? Any dealership? Tischer?

Thanks!

3,4,7 are the basic parts when doing the solenoids.I(as almost everyone else) remove the small filters(or what is left of them) on the solenoids...

Any BMW dealer can order the parts..

OEM may not be cheaper. This is including tax and a Canadian up charge on all things 210 canuck bucks for 2 gaskets and 16 O-rings.
If I may add a question, are the solenoids(not the whole board) available as singles and which is which? Are the top two exhaust or intake? Which are advance and re*tard outside of engine or inside?

I pay about 45€(60$ US) for all the parts from the dealer.

Solenoids are not individual available.Only as full board,BMW recently doubled the price to about 1000$ for those.
Pretty steep pricing...

Was lucky to get 3 new solenoid boards for not even 1/4 of the new price from a BMW dealer that quit business...

I could get you those gaskets/o-rings for about 50% less or more from a friend of mine at Maranello BMW. PM if you'd like me to get a quote for you.

Cant PM yet. I must say I have noticed that when BMW Durham went from corporate to a franchise that the prices doubled. I am quite anode and will not go back. When corporate the prices were reasonable enough I stopped asking the price. I don't think I will go back to the new store. Thanks for the offer, send me mail sailor2457(AT)gmail.com. I may be looking for a new board as I appear to have lost another solenoid.

I know, it really depends on the dealer nowadays. Check your email for the quote I got.
