Single VANOS parts question.

I searched, but couldn't find what I was looking for, or didn't have the correct terminology.

I've been looking at the spring plate and stop disc changes made to the Single VANOS unit from Rev 1 to Rev 2. The engine is a M50B25TU.

I'm curious if the cam side Stop Disc, 4mm (PN:11361735908) is interchangeable with Stop Disc, 4mm (PN:11361403823). What are the differences between these two parts if it is known? Material, machining, dimensions, etc?

If I am correct, I should be able update to Rev 2 with these parts:
Stop Disc, 2mm (PN:11361403822)
Diaphragm Spring (PN:11361403550)
3x of the new studs (PN:11361403824)


It makes sense to me, but I am sure people here are far more knowledgeable about this car than I. Is there any reason I should not update my VANOS to the revised design?

uh,....wut?? the m50 never got a technical upgrade, hence the 'tu' designation, as it was simply a single vanos motor. so it should be siply an m50b25.

as was the m52 until the e46 chassis where it became a m52bxxtu with dual vanos.


as for doing a vanos repair, was it noisy?? no need to do a 'repair' if the system is operating properly, even if there was an 'upgrade' along the lines somewhere.

a lof of guys like the dr vanos products, btw.

Sorry my bad. I use the M50B25TU internally in one of my spreadsheets, and have come to refer to the M50 VANOS as such.

Ive been rebuilding and getting familiar with all the various systems. I've found that typically rev 1 stuff is more prone to failure. That BMW felt the need to update the design is enough of a reason to look into it.

I am just checking with people who may have already crossed this part of the research & learning bridge.

Cheers!

meh,....i may be mistaken. i am so used to the m50 in vanos form that i forgot that it also came in non vanos mode very early on. so it may very well be designated m50b25tu with the vanos, but then that sorta is a weird thing to say since if you need vanos parts for the m50, it's the only version that *had* vanos.....unlike the m52 which was both single and dual vanos....and are different in that respect.


regardless, the m50 only had single vanos.



as for necessary parts, dr vanos has popular kits and a good rep, so i would use them as a source when the time comes.
