spring 'scrub up'

[M1ke]

Why can't I post pictures, clearly I'm completely inept...


I have uploaded to Flickr, used the insert image option and copied URL?

Well the Vanos is off, have to say so far the Beisan guide is very good.

Initial observations are that one of the exhaust solenoids has a leaky o-ring, will be interesting to see what condition the other seals are in. The unit still had all the factory paint marks on the screw heads so looks like it has done fairl well!

While it's off the cam cover has been stripped ready for paint.

Also going to check valve clearances ( I assume when re shimming it is best to aim for the tighter end of the tolerance?).

Can't wait to get it back on the road

I would aim for the higher end actually as the gap gets smaller as the valve seats wear over time so will get tighter with age. You will probably only have to change a couple anyway.

Looks like you could do with your M badges refreshing, give me a PM as I do refurb kits.

Having mine done by Mr Vanos this weekend.

[M1ke]

Not very successful with my photo uploading but badges have been done, combination of your kit and new side badges

Mr Vanos would certainly have been quicker!

[Aceman]

Cool, love the wheels by the way.

Probably the worst journal on here picture wise, sorry........

Quick update
Vanos fully re-built with Beisan kit and updated solenoid o-rings (m5), gaskets and Vanos filter from BMW.

Started and all appears ok. Have only driven around my works car park.....

The car has done 72 k and this is the first time the Vanos has been fully apart.

Comments.

Small o-ring on both exhaust solenoids were brittle ( You can see they have deformed below)

Solder connectors on solenoids had been previously repaired (by me), but I did a better job with them out.


Intake piston had little resistance (I have no reference to know if this is normal or not).
The Beisan procedure is excellent, I have very little spare time so had to do it over a few weeks, I'm sure it could be done in a day.

I will update once I have driven it properly to see if there is any noticeable change.

If you haven't checked your solenoids I think this is very worthwhile and very low cost. The full rebuild is certainly more involved but quite satisfying :-)

It lives again!!

Finally all back together after checking valves ( bit of a faff but got much easier) rocker cover and air intake painted with VHT. New o-rings on throttle body inlet trumpets.

A good spirited drive over cat and fiddle today it's seems to be revving much freer and pulling stronger (am sure the Vanos seals have improved it). Also rock solid idle

Exhaust is blowing badly though so you may have heard me from afar.

Next
Exhaust
Clutch release bearing (rattle)
Milky seals on front and rear screens.

Good work Mike!

Are you thinking of just fixing the blow or a whole new exhaust?

And the milky screens?

[M1ke]

It's going on the ramps on Friday. Hopefully it's just a gasket! Full exhaust going to have to be another time $$ :-(

The front screen I think just needs a new seal. Rear screen I'm going to try and get reconditioned. I don't fancy removing these myself though!
