criagslist 500 dollar beaters.
BTW, taking what he said, I still stand by my original theory- the build might have been done incorrectly. Without the build sheet, there's not much info left on how much each clearance of each bearing was. But according to another subie manual for a legacy gt 2.5 turbo (might be different for your year?)
Connecting rod oil clearance:
0.017 — 0.045 mm (0.0007 — 0.0018 in)
Your .004" was on a GOOD bearing- so who knows what else was going on in there. The bearings were way out of spec to begin with, unless someone had specified looser bearings for a high pressure oil pump, but then didn't put one in?
