Anybody able to help me out here? The YT roller rockers seem to be wearing excessively on the roller part. Plenty of oil up there. I wonder why the roller has marks all the way around....it shouldn’t be spinning like that. Preload is .030 on Johnson 2110 lifters. I may be switching back to stock. Some look like this. Some don’t. I’ll get I touch with YT on this as well. If they missed a heat treatment or something I guess it’s a possibility.
