Vanos rebuild

Ha yeah, fair one. I think I paid him about that nearly 10 years ago on my E36 M. He does have a rather unique market niche though. I deffo had an abnormal noise on my Z4 not the usual rattle, more a whirring sound. And not a single other specialist I'm aware of offers an exchange service on the unit (I spoke to many). It was basically spend X amount of money diagnosing a fault / replacing parts which could be many things (stupidly I did initially) and a refurb unit was the only thing that fixed it and runs quiet as a mouse now. Took ages to get to that point mind, he is a pain in the ass to get hold of, although I believe he does have personal circumstances which dictate that in fairness, let alone a 2 month odd waiting list for work.markos wrote: ↑Sat Jan 20, 2018 12:15 amI remember about 6 years back Mr Vanos was around £600, definitely not more. He was sorting out a friend's Z3M, I brought mine over and asked him to have a listen to mine, which he did and he thought it needed doing. To my ears – and my friend's – we couldn't hear what he was on about. 5 years and 20k+ miles later (and asking every M tech who ever serviced the car to listen for any VANOS noises – which they never heard) the car ran perfectly, no issues, no unusual noises or rattles apart from the usual S54 noises. Guess his ear was a lot sharper than everyone elses.
Thanks Guidok, what I thought. On that, you're a knowledgeable chap, what's your thoughts on the VANOS and various repair methods? The topic still interests me after my trails and tribulations with it! Always wondered if on the German forums there would be any different points of view on it for example.
Well the whole Besian method of rebuilding. The seal (o-ring) kit seems fair, and obviously the new bolts are neccasary as BMW revised the design themselves.
I dont have hands on experience with the s54 vanos, but I doubt the anti rattle kit is necessary. If in that region (so the axial bearing that sits in the splined helix gear) develops more play than from factory, it can only come from wear from that bearing (in which case that bearing is scrap).
I think if the solenoid pack functions, it functions.solenoid and valve block parts
I dont know. I only know that a complete unit from bmw is 2k, so very expensive., I never did understand why you would replace the seals in the valve sealing plate when a new one of those from BMW is pounds anyway for example. [/quote[
They replace the original bmw seals (made from NBR) with viton seals that are supposed to be more heat resistant and last longer.
But if you take a new valve seal plate you're also good for many years.
Any failure is easily spotted as it would leak to the outside. A new bmw seal plate is about £25.

Out of interest, do you know if BMW actually supply a new VANOS unit these days or if they just refurb units themselves...I was under the impression it was the latter?
I thought that had only happened with the earlier versions (V1, V2, made from 4130 and 4340)?
i was suprised too!!!! but yeah!!! their have been breakages.......GuidoK wrote: ↑Sun Jan 21, 2018 2:24 amI thought that had only happened with the earlier versions (V1, V2, made from 4130 and 4340)?
