No leak down.... Based on what I know about the motor, it is likely the only thing it needs is a once over bore and new pistons. Heads, crank and maybe even rods should be fine. It has always been well oiled and under detonated. I think the only reason the rings failed is after 85K of seating and wearing on the cylinder walls, I asked them to go an extra few thousandths of an inch by increasing boost and max RPM and then taking it to the track for 5K miles or so...
Crashing into any cylinder wall ridge has got to hurt.
But anyway, unless I get a great offer, it is likely I will tear the block apart at least splitting the heads off for my own edification and investigation.
