Rebuilding the vanos

This something I'd like to do over the winter. Has anyone actually rebuild theirs themselves or is best advice to drop it into an Indy?
 
How much DIY experience do you have? What's the most complex thing you've done on a car engine?

VANOS rebuild isn't particularly difficult, but does require an extensive set of tools (including some special tools) and some solid knowledge of mechanical assembly techniques.

The Beisan guides are fantastic and I'm a big proponent of DIY but screwing up on the VANOS can be catastrophic so it's not something I wouls recommend to a novice.

I'm an ex aircraft mechanic so there's very little that would phase me on a car. It is the need for specialist tools that is the kicker - if they are expensive for a one time use then it may we'll be an Indy job. I just love doing my own stuff on my car.

Oh mate in that case go for it - with that kind of background I couldn't imagine paying someone for automotive work! I love doing my own work on the Z4M so much that it's now 100% self serviced. In my case an engineering background is a big help ;)

You can get cheap VANOS locking tools on eBay. Apparently the quality can be a bit hit and miss but with a background such as yours you should be able to rectify any shortcomings.

According to some on here though your cars will lack the service stamps which will make your cars unsaleable and scrap only! I'm in the same boat :rofl: :rofl: :rofl:

Haha very true buddy ๐Ÿ˜Š Things is for the less complicated jobs, why on earth would I pay to get the stamps i.e. ยฃ36 and 30 mins to replace the diff oil. My quote was around ยฃ170!!!
 
The way I see it, the amount of money I save from DIY servicing more than offsets any decrease in the car's value because of it (that said, cost isn't my main motivation - I just like working on my car!).

I plan to keep the car for a long time and put plenty of fun kms on it so depreciation is not on my list of concerns. Still, I'm convinced that the right enthusiast buyer would appreciate that in reality a car that is DIY serviced by a passionate, knowledge amateur can in many cases have been better looked after than one with full BMW service history ;)

Couldn't agree more!!
 
Also, when the cars have reached a certain age, it'll be the one's which are owned by the knowledgeable and capable amateurs which will be the best maintained too because we don't have to pay for our own time spent on the car and we enjoy doing the work. :thumbsup:
 
It makes me happy to hear so many like-minded Z4M enthusiasts getting their hands dirty. The S54 in the Z4 package is a fantastic engine to work on!
 
Changed my M's angel light bulbs to a higher grade... All by myself lol... Justifiably proud but I don't think I would mess with the Vanos solenoid for my DD 2.0 though, as it seems to need it (Running out of puff and flat spots). Throttle reset helped a little bit.

Does anyone have any idea of costs? And garages in or near Medway? Thanks.

An ineffectual vanos should show itself as a lack of low down torque, not running out of puff at high rpm?
