Luis,

About 4 or 5 posts back I detailed how to take the adjusting unit and sealing plate off. Let me be a bit more clear: when unscrewing the allen bolts, screw them COUNTERCLOCKWISE to loosen, then clockwise to tighten during reassembly.

C'mon man, it's not hard Go out and do it. Just try to keep things clean, and keep junk out of the oil ports that you will see in the adjusting unit.

First of all please do this with a cold engine. A little oil will come out and will burn the crap out of you and the vanos unit stays hot for a long time. (Learned this first hand)

You will first need to take out the left side of the plastic black fan shroud. There are two pins/clips that you will need to take out to remove this. Next take out the 5 hex bolts from the top of the VANOS. That will allow the solenoid to drop down which should allow the sealing plate to slide out. If you want to you can unplug the wires from the left side and remove the entire solenoid unit for better cleaning, but I was in a hurry and just simply slid out the old plate, wiped the oil from the solenoid and slid the new plate in its place and bolted the thing back on. Put your fan shroud back on and fire her up! If you have any other questions let me know.

Quick question, I replaced the filter cartridge (#4) and the bigger rubber o-ring (#6); I also bought the smaller o-ring (#5) however I fail to see where that one goes on my pressure valve. There's no room for it nor was there an "old" one anywhere on the vavle. Any comments?

Thanks. Looks like we have the same stuff. I too have some kind of washer made of hard plastic there, not a rubber o-ring. I don't see it being a problem at all. My car is an 01 FWIW, maybe they changed things over the years.

I believe a good soul should recollect all the additional useful information provided here and produce a step by step DIY with pics to clarify any doubts - I personally like pictures when it comes down to DIYs and parts. There is a lot of trial/error feedback in this thread that supplements Tonester's original post that should contribute to an excellent DIY

Now, all we need is a good soul with enough time and patience in his hands!
