I would look for a different place to pull oil from the rockers.
I find a place that puts oil to the rockers before it gets to the main oil gallery.
I’m just not a fan of pulling any oil out of that oil gallery.
On a Ritter I’m not sure where they would be without getting my eyes on the block but on any other block I pull the oil off the gallery that feeds the oil
pressure gauge.
I can take some pictures of what I do or maybe a video if I feel like it.
I want every drop of oil going to the bearings and not taking oil off the crank to feed the rockers.
