Hi there,
this lockdown thing has given me the time to work on something everyone recommends doing, and I don't know if it the VANOS issue is perhaps too exaggerated, or not. But since I love the car and plan to keep it for long, I am doing the VANOS this week.
I don't pretend to do a DIY as a whole, but to provide reference information and images that I have found difficult to get.
So let me first detailing the parts I am getting
1. S54 Valve Adjustment Kit - With Gaskets ES#1893858 as I will be doing my valve adjustment while the cover is off
2. Camshaft Alignment Tool ES#199268
3. ALIGNMENT PIN ES#199978 (This has to be Z4M Specific)
4. Vanos Unit upgraded bolts (not the sprockets, but the ones that attach the unit to the engine
- 07129905554 x3
- 07129905537 x2
5. Vanos Connector (I was stupid enough to break mine while unplugging it
- 61138383300, see this video in youtube, is excelent.
6. Vanos Hub and Sprocket upgraded fasteners
- 07119913589 x12
- 07129905536 x12
7. Vanos Gasket
8. Chain Tensioner Bolt Crush Washer (07119963418 x1)
9. Tensioner Guide Bolt Crush Washer (07119963342 x1)
10. High-pressure oil pipe banjo bolt crush washer (07119963072 x2)
11. Oil Return pipe crush washer (07119963129 x2)
12. Vanos Hub Diaphragm spring from S62-V8 (11367833218 x2)
13. Beisan Systems seal kit
14. Beisan Systems Oil Pump Disc
15. Beisan Systems Rattle Fix Kit and Tools
And there are more items like tools, etc. but I wanted to list out just the parts
Next, I removed a few things to facilitate the Vanos unit removal/installation.
As you can see below, without the cooling fan there is way more access to the crank pulley, which allows for easy rotation of the engine for timing procedure
Next, you take the cam cover out, and move the harness for the coil packs, O2 sensors, etc. out of the way, you can easily put that aside towards the far RH corner of the engine bay
