Titanium spring retainers

Locomotion said
Here is an example of near disaster I experienced. "Stock class" style cam with .474" lift but with very fast opening rates. Spring pressures were about 160-180 seat/360-380 open with Schubeck/Smith composite puck hydraulic lifters. Other retainers were intact, but pretty beat up. I upped the spring pressures to about 200/400 and the problem went away and valve adjustment remained more consistent between adjustments.

I just had to check the spring pressures between seasons to maintain the "safer", higher pressures.

As for aluminum retainers.....put them in the aluminum recycling bin!

If you are hurting valve train the first thing to do is up the pressure just like you did. I’ve seen more valve train death from losing spring load than I ever have from being over sprung.

To really dig the pepper out of the fly poop you really need access to (or if you are J.R. Gottrocks you can just buy one but this dirt port white boy ain’t got that kind of cabbage) a spintron so you can actually test what you are doing.

I was hoping that by now the spintron would be about as common as an engine Dyno, but it ain’t happened yet.
