My “armchair quarterback” response is........I would have installed the new cam at the same c/l as the previous cam.
I watched the video.......and that does look like a ton of oil coming to the top. Although, in all fairness.......I’ve never run anything with a clear v/c.......so I don’t really have anything to compare to. It just “seems” like that’s a lot of oil up top.
