Well, I'll maybe update at each big upgrade/mod.
Right now I've been shooting the pull n pay for timing belt covers. My contact on the Isuzu forum that can get everyone factory new parts says my only option for new valve covers, is ordering them new from Japan for about $40 a piece.
The, pretty sure original, water pump seized and bent the shaft, so it popped the belt out of alignment just enough to burn lines through all three timing covers.
