VANOS Rebuild

[~CSL~]

I bought a complete new VANOS from Bimmerworld last Black/Orange sale (2025). I haven't pulled it out of the packaging but based on their listing photos it appears to have new hub splined shafts with it and solenoid pack. At the time, the pricing was not much more than a new solenoid pack.

Thanks, appreciate that

To measure the oil pressure, are the Lang and MLR kits my only options? I’m seeing both as sold out. I found An old thread about somebody making their own kit for it but that sounds sketchy lol

I recently bought a pressure gauge, an adapter and a bango bolt - the banjo, adapter and pressure gauge all fit together, but I have not tested on the car yet. This is the gauge I picked up:

Ashcroft 1009 2-1/2" & 3-1/2" Duralife Pressure Gauges

Care to drop some links for those? 👀

I edited the original post the the names - the last two were on amazon, confirmed the M10 x 1 here. The gauge was from Brice Barclay

Beautiful, thank you. Going to order some crush washers from FCP as well and give it a go. I’m also seeing that red loctite should be used to seal the gauge into the adapter, but can’t find which kind exactly. Loctite 271?

I’m also trying to find pressure specifications for the adapter and banjo. I’d rather not die from an adapter flying through my skull. Bleeding out on top of an S54 isn’t the worst way to go out though I guess

It is not my intention to red loctite the gauge onto the adapter - this is only a temp assembly for me.

Getting the adapter in SS would be a better choice if this is a concern.

Just use plumbing teflon tape on the threads, couple turns is enough.

I rewatched Imrans video with Dr Vanos from a couple years ago and he mentioned something about how shuddering during takeoff with SMG cars can come from the Vanos. That is something that I feel periodically, not every time I’m accelerating from a stop. It’s a fairly significant shuddering that stops once I hit about 2k rpm. Always attributed it to my clutch or something with my diff, and the car stopping with gears or the clutch engaged perfectly on a worn part. Is that something you guys have heard about, it coming from the Vanos?

Try resetting the engine and SMG adaptations.

Im curious, if you go out to your car with it warm and in Neutral and have somebody just tap the accelerator, say from idle to 1100-1200 rpm, just momentarily (blip the throttle) do you hear a "rattle"? This is not the usual Vanos Rattle - its the one you shown in this thread:

No it doesn’t make that noise

That’s the one I am chasing now…
