Just to make things clear---and I've obviously left a few details out---the G63B I pulled out of the truck is not worth rebuilding.

I went over the head a second time and found a crack between the seats of cylinder two. The valves and valve seats are pitted. I pulled the pistons and found the skirts skuffed, scratched and blackened. The cylinders walls are discolored with vertical scratches. I don't have access to a bore gauge but I'm betting the block would need to be bored and not simply honed out. The main bearings and rod bearings are black and blue and scratched with dirt particles embedded. It's miraculous the engine even started. I don't think the previous owner believed in oil changes. So add up the cost of machine work for the block and crank, sourcing another head from somewhere, pistons, rods, bearings, rings, gaskets, belts, hoses, spark plugs, a new egr valve, rebuilding the carburetor and whatever I've left out and even if the operation is a complete success I would still have a carbureted engine that will be a bitch to get smogged every two years and for which many parts are becoming scarce.

A 2.4L fuel injected Toyota sounds good to me.
