Morning Klaus,

I will try to attach a picture of the cam sprockets. If I am successful you will see where I have put some marks [A&B]on the image. My foremost gear [the intake cam?] is blue. My aft gear [exhaust cam?] is unpainted grey.

If I put some paint splotches at A and B would they be useful when it comes time to reassemble? I can't seem to get behind these sprockets to make marks that cover the sprocket and its shaft.

I had another go at the turbo-to-manifold nuts but cannot get to the fourth nut from on top. I will try from underneath next.

Strange but the wrench that fits the nuts best is a half inch. The thirteen mm fits but is a little loose. Twelve is too small. The half is perfect.

I also wanted to note that there is an "M" stamped on both gears. Don't know what that means. I have been using the single 'cut' on the aft gear as a marker.
