Exhaust, both times. The first one I figured was a fluke, that it got damaged when the rocker assembly came loose. But this second one was also an exhaust valve.
And I just pulled the spring on that #1 exhaust valve; spring looked in good shape and the valve spun freely and moved up and down freely(well, the small amount possible at TDC).
So... I'm thinking valve springs will help. I'm sure the drive pressure is totally out the window - I've never even *heard* of someone getting 20+ PSI out of a TE06H, so I'm sure it's *really high*. But yeah, I do want a better turbo as soon as I can afford it.
BTW:
https://www.ford-trucks.com/forums/1...e-springs.html ref my other topic about valve springs, for future readers.
At this point, my springs *should* be here tomorrow if my luck holds. I have stamped out some .050 shims which will fit /under/ the rotaters, which should keep them from wearing; I made them out of mild steel. It looks like using .050 shims for an installed height of 1.75 should give me an open pressure in the low 300's, and a closed pressure of like 140lbs. I think those are good numbers, as long as I can keep the rockers holding good. I do think the weak point here is going to be the pushrods, which is OK with me; pushrods are very cheap compared to any other part of the valve train.

SMF flywheel. What brand? I'm not sure. My dad bought it and had it installed on a previous truck, which I ended up acquiring for mine. He doesn't know what brand either.
It's pretty stiff, but seems to work well.

OK, it's done. Swapped out all 16 springs for the new ones, with .050 shims under each.
