E46 M3 S54 Vanos pressure tests

[Ahmed.Alghoul]

Need more information about the vanos fitting adapter size ,where could find online.

The video shows the pressure reached 140 bars which is too high. Should be 115 bars max.

The graph shows the accumulator (not actuator as in the data table) seems to be fine with pressure slowly drop over 1 minute. Bad ACC would cause the pressure to drop very fast.

Edited: I was wrong: the video shows 114 bars which is OK, not 140.

Results from my Vanos tests carried out recently, (UK custom guage kit off EBay).
Its somewhat more thorough than the one I'd posted out back in 2016, where I had faults causing v low vanos oil pressure and Ive defined some simple benchmarks, this so that with others data, we could look at establishing indicators that can help us determine whether our systems are at full health.
Am keen to get your feedback (and data points) to work this one further up, please comment.

Would you add the link for the uk custom guage kit in ebay.

Having a little trouble uploading a revised pic for the benchmark table onto the original post.

Here are the results, (graph & results table inc two Id done a while back).
Because my pressure has fallen a little, and the mechanical response times have slowed slightly, I think Im now ready for fresh Beisan piston seals.
