How to Repair the S50B32 VANOS

Postby pingu » Fri 16 Sep, 2016 04:22

Hopefully these videos will help you decide if you want to take on the dreaded rattle or poor performance.

It will cost you around £150 to get it sorted if you DIY. Now that I know what I'm doing, I could do the full repair in a long day.

You should still read the Beisan instructions (Seal Replacement and Rattle Procedure) before you attempt the repair, but I'd also advise you to view my videos as well. Also read the BMW TIS if you have access to it.

There are linked videos within the videos and I'm not sure how the YouTube viewer will handle them, so I've included the links so you can go directly to the source if it all goes wrong :) ....

I've just priced the whole job.

Seal Kit - Beisan - $80 (£65). Best price on eBay is £55 (includes the solenoid seals which Beisan doesn't include)
Anti-Rattle Kit - Beisan - $80 (£65)
Anti-Rattle Tool - Beisan - $20 (£16) You could try to hold the pinion in a vice, but you would probably fail without the tool and damage the pinion.
Camshaft and Crankshaft Timing Tools - eBay - £46 (not essential, but makes the job a lot easier)
Solenoid Plug Diodes - eBay - £10.33 for various diodes, most of which were wrong. The correct ones cost £2.95 for 10, but I only needed 2.
Diaphragm Springs - BMW - £48.21 (£43.39 with 10% discount)
Solenoid O-Rings - BMW - £49.97 (included in eBay kit)
Timing Chain Tensioner Seal - BMW - £0.30
Solenoid Cover Gaskets - BMW - £16.06 (not required unless badly damaged)
Thrust Washer - BMW - £7.72 (£6.95 with 10% discount)
3x Valve Shims - eBay - £10.03

Some switches and terminals to make a solenoid activation tool - eBay - £3.80
I also had to buy a 24mm open-ended spanner - Halfords - £9.99

So, the total cost was just a little bit under £350, but with more knowledge (and if I had the tools, or make do without them) I could have done it for around £210.

Great job! I am replacing the rocker cover gasket and thought I would replace the Vanos seals while I have it all apart anyway. Just waiting on the parts now. No other work will be done.
