Dual Vanos Repair Results: share your experience

What are some of the things you've experienced after installing a new VANOS system?

I did not have the MAF or the air cabin filter completely installed. Tonight I was only checking to see if the engine would turn over.

during this project, I installed a new DISA valve, new intake and exhaust cam sensors, new Spark plugs (NGK), new VANOS seals and a Dual Vanos unit from Dr. Vanos, and a new AC belt.

What? You checked if the VANOS was installed correctly?

Before putting the cover, the fan, and the MAF back together, which I wasn't going to have time to do, I asked the mechanic if it would be ok to turn the engine on to see if there was any rattle and if I put everything back together correctly. There was no rattle and the engine turned on.

I'm working at an auto hobby shop. I have a bay and tools. The only inconvenience is that they close at 730.

For the record, we haven't yet determined HOW to test VANOS operation successfully.
- How to objectively test VANOS seals in operation (1)

We have been successful in determining your options though:
- What options do you have for your engine VANOS repair

And, we have some videos of VANOS rattling noises:
- VANOS rattling noise video (1) (2)

And, some people make their own VANOS tools:
- How to make your own VANOS tools (1) & socket tools (1)

These links are all from the VERY best of E39 Links but most should apply to the E46 (I hope):

- I6 VANOS SEALS DETERIORATE: they're made out of the wrong materials so that they harden and leak over time causing degraded performance (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) (11) & how VANOS works (1) (2) (3) & what your options are (1) and vanos application table (1)

I sincerely hope these help.
