Valve cover removed with some effort.
Here are pics of what I found.
The cover has apparently been already removed.
Either the guys changed the seal (gasket) and added a lot of silicone sealant or they just added silicone sealant to the cracked seal.
I don't have any sealant at hand. I will just clean everything and put only the cover seal and the spark plug seals.
Engine looks dirty.
I found out about the VR6 shifter rod two days ago while working on the treg. When I removed the intake manifold I found the rod has a lot of play. I do have a rolling marbles sound at 1500 rpm and on higher load. I thought it was due to stretched chain but VCDS measurements say I still have a good chain. The rattle is probably the manifold shifter rod. I cannot get it out of the instake manifold for the moment. I'll leave it be. I will replace it later.

Nothing special to check on the VR6 that I know of.

There is the throttle body. I think I'm going to remove from the intake manifold and clean it. It doesn't look bad fron the outside. There is of course a certain amount of dirt but not too bad. I don't know if I will need to replace any seals when reinstalling it. Etka to the rescue.

I spent a good part of the afternoon removing the old seal and sealant from the engine and the valve cover and discovered that I will certainly have to use silicone sealant too. The guy who worked on the engine before used a metalic tool to remove the old seal and scratched the seal surface on the engine side. There are some dents and some serious scratches. Not sure sanding the surface will help or make things worse. I think that even sealant will not seal good enough with these scratches.

Although I have V 8's, before I changed the valve cover gaskets on both vehicles I asked my mechanic buddy if I should use RTV (gasket silicone) and he said I shouldn't have to. After about 1000 miles I checked the wife's coils and all but 1 spark plug tube had oil in them. I ended up having to do both cars again and used the sealant the second time around. On mine there was a valve cover bolts loosening pattern outside bolts to center and opposite for tightening. Keep up the good work.

Thanks for the info.
I will clean and sand the mating surface and use a Red RTV I have laying around. Max temp is 360 I think.
