When's the last time a lifter wheel diameter was checked. Has it EVER. Advantage?
My recent lifter problem is due to coating. Coatings seem to not hold up. I really don't understand why not. I'm a retired tool & die maker/maintenance so I've seen and know the extreme pressures steels are under in die stamping/forming and coatings holding up in those operations. AND usually with very little cooling from oil, etc. What I'm trying to understand is how at the pressures of a lifter/valve spring (on a stocker) that the coatings will not hold up. Some of those forming/stamping operations use thousands of pounds of force with absolutely no or very little wear.
I'm sure (from emails I've received) that I'm not the only one fighting this problem. It makes since that a smaller lift and lighter weight valve train doesn't seem to have the problem. My problem is complicated by the fact that all flat tappet motors are at a disadvantage because of lifter surface and roller lifters are adjustable by roller wheel, bushed wheels and oils.
