It won't turn over. I pulled the plugs thinking there might be water in the cylinders and 2-4 look ok but 1 has a very shiny top of the piston. There is no obvious rod through the block wall but I haven't pulled the head yet. I'm hoping for a bent valve.

I have been building engines for years. Mostly american ones - I have a 429 in the Cobra. Who has good prices on rebuild kits for Hondas. Summit charges $350 or so for a complete kit withpistons for a Chev 350 and the same amount for the rods alone in a Honda.
It seems the whole industry is trying to put one over on the Import people by charging an incredible amount for parts.
