Engine Experts, Camshaft Button, why need one?
I'm trying to figure out how the camshaft would ever want to move towards the front. The gear geometry of the oil pump gear would suck the cam in. Is this a 9000 RPM closed throttle situation or something? Maybe if the engine starts backwards I suppose. What am I missing here in my logic?
Thanks!
Thanks!

Roller lifters can't tolerate any axial motion. The distributor gear isn't enough to keep it back against the block.
Not needed with flat tappet lifters.

One piece rear main seal blocks use a cam retaining plate to do the job
a cam button does on earlier blocks.
