Failed vanos test post Beisan

[eacmen]

Well I did.
I bought a complete set of Beisan's stuff (except for the re-drilled disc) for my unit, which was working ok, as a preventative measure.
Ended up running a vanos which would never pass the test, working pressure was only 30bar, dyno curve was flat after 6500rpm. I even replaced every part that BMW provided for it and still wouldn't work.
I contacted Raj who wasn't very helpful and everything was back to normal after I installed another used VANOS unit.

There are several vendors that use Beisan parts to rebuild units and bench pressure test them before shipping them out.

Ive used Mike from Naturally Agitated and been very happy. But there are a few out there.

Without the ability to bench test the unit youre sort of gambling until you get everything back together as not every VANOS unit is in rebuildable condition.

Fuck, I sure hope this doesn't end with me having to buy a brand new vanos to make it right.

I don’t think anything would have satiated that particular user’s bloodlust.

tl:dr:

Are there issues with Raj’s oil pump discs? possibly

Will Raj offer good customer service if you have issues? certainly

Will every customer be happy? likely not

oh i got no beef with Beisan, just curious what ended up happening, and was bummed the thread was deleted.

hey what ever happened to the guy that was having problems with his vanos disc from beisan? I went to go look for the thread to see how it was resolved but the thread was deleted.... Hope that means the issue was taken care of!

Just a final note, Raj has been very helpful throughout all of this and sent me the gauge to test and the different disc as well.
He has sent me a full refund for my entire purchase, I didn't ask for any of that, he offered and I accepted.
I am sending the disc back today so he can inspect it.

Not sure if this has been posted yet:

Look at page 49, in reference to this S54 engine:

The oil pressure for this high-pressure VANOS was raised from 100 bar to 115 bar

[maupineda]

Just like that, as opposed to the thin tin nut on the original part.

Does your new valve’s locking nut made out of solid metal as this one:

[maupineda]

According to a source, the new revised valve is this one with 115 bar set: 11367838080.

Negative, that is the part number I bought back in September 2020 from www.getbmwparts.com

It always kinda surprises me that 20 years later, there aren't straight answers for these kinds of things. It feels crazy to me that none of the guys who designed and specced these engines are the type of car guys to want to talk about these things with enthusiasts and put knowledge out there for them?

I've thought about that a lot too. Imagine how much speculation could be avoided if just one of the engineers who worked on the S54 was on here.

Ah I missed that from your post. Well, guess there's no straight answer.

That was my thinking initially but since a brand new item is capped at 100 bar, that conflicts with the revision theory, otherwise the new part would be calibrated at 115. And it is not.

i did not tamper with the new valve, but with the old I did, and I was able to set it to 115 as when cold my VANOS does reach high pressure. My car is an 07 Z4M, so at least in that application the OE valve was still at 100. So we are entitled to believe what we want on this one. Perhaps on the E46 was set higher at some point, but Real OEM shoes the same part number for the E86 and the E46. Mystery.
