Anyone here rebuild their own vanos unit?
Discussion
I've eliminated everything else that can be causing the rough idle on my e36 3.2 and all that's left is the vanos unit not keeping oil pressure. Just been reading the besian guid to replacing all the seals and i'm thinkig about having a go at this myself. I don't need to touch the solenoids or the rattle repair on the splined sections.
So, anyone tried this?

Done that a couple of times.
No, i mean physically take the unit off the engine and replace all the oil seals in the internals of the unit itself. When mine's at running temp the internal oil pressure drops too low on idle. One of the buggers or possibly several, has worn out and it's not running full bar anymore.
I've budgeted a week to do it over xmas.

You will need to timing kit to replace the Vanos of course. I can't comment on the rebuild options but the timing job is quite involved. PM me if you need the kit, I have one here on a shelf you can use.No, i mean physically take the unit off the engine and replace all the oil seals in the internals of the unit itself.

The beisan kit write up seemed to suggest i wouldn't need to lock the cams or remove/adjust the timing, have i missed something here? It's just the oil seals inside the vanos unit itself, i'd be leaving the helical splined bits on the car still. There's a minor bit of cam position adjustment but nothing really timing related. This is the write up i followed...

There isn't much else to replace, there is an oil pump accessible from the front under a cover which has an O ring on it, and a pressure plunger thingy on the side.No, i mean physically take the unit off the engine and replace all the oil seals in the internals of the unit itself.

Any pics of the bits you are thinking of?

Could you tell me a bit more about the oil pump/cover please?
OK, that write up is a fair bit different to the ones that I have done.
Apologies if I have thrown you off track. The ones I did were on the older E36 engines, where the cams needed to be locked, and I did a fair bit of work on the timing and variable inlet stuff on the (I think) N42 engines. Both these needed timing kits, and could not be done without.
Either way, tools on the shelf if you wish.
Cheers

That's brilliant, thanks again for the offer. I may well take you up on it!Apologies if I have thrown you off track.

I'm crapping myself about doing it but everything else has been exhausted. I just got quite a big labour and vat bill for the last round of work it had done so looking to try and economise a little. Don't think the job is beyond me, but i'll need to take my time with it.

The oil pump part is the star-shaped 6 bolt circle off to one side.http://www.beisansystems.com/images/bs041_large.jp...

Undo the six bolts, the cover comes off, part 6 and O ring 7

The plunger is part 2 with associated O-rings.
All apart from 19 and 20 can be done without removing the vanos unit from the head.
