M54 Engine Vanos Seals

[billdo]

Do you have to worry about timing when doing the Double Vanos on the M54? The timing is really discouraging me from doing it on the M62tu.

Nope.

Thanks Ricky, the DrVanos DIY is confusing in that regard, whereas Besian doesn't show anything about timing.

No timing issues during my x5 VANOS rebuild. Good question. Better to ask

No problem. Don't follow DrVanos I would follow Besian Systems diy to a T it's perfect instructions.

Are you installing anti rattle kit too? I guess you don't have to if you don't have rattle but if I had it open I just might do it

I did the Besian anti-rattle kit (and full seal upgrades, etc.) on my 2002 M3. The anti rattle kit is worth every penny. Do it if you like a quiet running engine.

I will put the anti rattle on it too. However I will have to postpone this fix. As I am redoing the whole front of the engine on a E39 540iM I just got. Most ambitious repair yet.

2001 E53 3.0i M54, 186k miles

was running with no problems at all other than head gasket letting combustion gases into the coolant

I've owned for 4 years now, PO had extensive maintenance done, mostly at the dealer. Sometimes incomplete records, but there is no indication of any VANOS work.

So I'm about to start re-assembly during my head gasket repair. The double VANOS is already removed, in hand.

With no symptoms, high mileage, and the VANOS already off the engine, should I go ahead and replace the VANOS o-rings (or whatever is in the kit) pre-emptively?

Thanks.

I have a post in this thread with more experience details.
My experience was noticeably positive.

[oldskewel]

Thanks.

I see the o-rings replacement is one part of the refresh. And the anti-rattle rings can be replaced as well. It looks like those are probably slightly thicker rings to account for accumulated chain/etc. wear. Again, worth doing if I have no symptoms yet? Those rings are supposed to address the "rattle" problem.
