Well I'm guessing it was the valve springs, or more so how they were set up, a stack of shims and no locator, the damper (with no locator) was bashing the shims and sending metal through the engine. I'm guessing some got through the filter. Also has the wrong retainers for the springs. Springs were pretty soft but hell maybe they are setup this way to loft the valve open or something with this square cam. One thing I didn't count on were the janky cylinders in the block, almost look rusted near the top of a few of them, we'll clean them up as good as we can... we gotta race.

I like to use a L31 Vortec retainer, with a -.050 tool steel keepers, and an Engine pro 1.250 cup locator with that set up. Light weight, simple and cheap, and it won't make metal, deburr the damper and spring ends.

Thank you.

Worked on cleaning some stuff today, chasing bolt holes and getting the heads cleaned and ready for a valve job and reassembly. I think we figured out the spring stuff needed. Gotta get a parts list started.

Hi,

I guess that nobody mentioned putting magnets in the area of the drain back holes, in the head, to catch all of the metal that the valve train sheds??

They can also be placed in the valley..

That's a real old trick..

Good luck,
Bob

X2 on the Pac1409X and the retainers. Excellent value for the money.
