Great video. I had no idea this problem existed. Here's another tip. Forget the Senloc washers. The use of them is an attempt to stop the oil AFTER it passes through the cover. Cut 1/2" (approximate) sections of rubber fuel line that will fit over the studs. When the cover is installed, these will form a seal against it preventing the oil from passing through the cover in the first place.
Solved my cam cover leaking by simply gluing 4 sheets of sandpaper to a flat surface. Then moving the cover over the sandpaper in a figure eight motion until the cover was completely flat. Solved the leakingm completely.
Sounds like a good simple solution for your issue. It wouldn't have worked for me as the cover was being held off the head buy the studs that were too long.
Interesting, but about that elephant in the room…. You forgot to mention there’s a cork gasket that goes between the head and the valve cover that’s about 3mm thick. That should account for any interference with the camshaft studs.
Think about it. If there is a 3mm gap between the head and cam cover a 3mm gasket wont be compressed. I my case the gap wasn't even all the way round so some part would be compressed and other parts wouldn't. I didn't want to rely on silicone sealant alone to get a seal
