This is a little bit about how to disassemble your vanos and clean it. Do this at your own risk. My vanos was disgusting, these pictures were after it was cleaned.
Here is the labeling I have of things..I am bad at terms, so correct me.
Step one remove the Pistons by pushing them out from this side:
Next remove the Circ Clip, the sealing ring, and then the pump. This picture is a clean one..
This picture has the pistons still in the vanos because I was reassembling it...It doesn't matter the order.
Next clean out all the little holes. Inside the pistons there are holes in there too. These red markings are just an estimate. I use brake cleaner and compressed air.
Flip it and clean the other side. Make sure you clean the bearings, cylinders, etc. When you clean these holes, flip the other side and cleanup what mess it made on the other side. Repeat these process's until your vanos is clean.
Oil everything well. Especially the bearings. Be careful putting the pump back on. The ring is held on by pressure of the 4 pistons that come out of the center piece. If the outer circle comes off, these pistons will shoot across the room. Ask me how I know. If this happens, I have a method to put it back together.
I am fixing a head of a e36 m3 to help pay for this work...so it'll be delayed a bit. Making progress though, got the top covers on. Apparently I didn't get a gasket ring for the support valve(only got one). It's ordered and then the vanos's will go on. The thing is, I will probably only do this once, but I could do it again in about 1/4 the time .
You should also add part numbers what to order before starting this project
Hmm, or was it that there is none of the parts available in BMW? I have my Vanos units rebuilt by Raikku, and I cannot remember now was all the parts new ones or what...
