Piston pin bad ?

I have more questions than answers myself..

I agree the piston looks like it had water on it, it would take a large quantity of fluid to cover the entire piston on a V8, and were it condensation from aspirating thru an open valve, for 6 yrs, I feel the condensation would accumulate at the bottom of the piston,, not evenly coated across the surface..

At this point we need more info,, or as you said it's speculation..

As for the rockers shafts,, they may be a completely diff issue unless they held a valve open that contacted the piston, causing the damage, yada yada.. lol

The skirts would perhaps indicate if detonation was taking place,, and I have seen detonation on a single piston.. If it was detonation, the heat and pressure is astounding, and could cause the piston/ring failure, that broke the piston yada yada that Jack built.. lol

hope it helps

PS ..can someone give me an opinion on the ex. seat post 87, I think.. Might just be my eyes again..
