The underside with oil pump removed. I had to remove it to get to the broken chain to tie a wire on the end.

Shame it happened to such a nice wagon. Were there tell tale signs before the vac pump grenaded?

Did you check for bent valves before deciding to roll in a new chain?

I pushed on each valve, and none felt like they were sticking. I also turned each one, and they all had the same resistance. I am confident no valves are bent. Although I have not heard of too many people repairing this kind of damage without removing the head or entire engine, I have done one other repair of this kind, and the car is still running to this day. Both the owner and I thought it was worth the parts and labor to try to fix the existing engine before just replacing it with the rebuilt one. I will know for sure in a couple days after the parts arrive, and I get it back together.....Rich
