Anti-pump-up lifters are pumping down.
By Dave Shoe - 07/23/2002 3:27:30 PM; IP 12.104.160.195
I suspect you have anti-pump-up lifters in that engine.

Since regular lifters have a tendency to pump up at high RPMs, anti-pump-up lifters are designed to pump down at speed. Ideally , lifters would "stay right where they are supposed to", but reality doesn't quite work this way.

This also irritates me, so I've switched to solids.

Just my opinion,
Shoe.
