time for a new long block
i ended up cracking a piston in my truck and found a new (refurbed) long block for the same price as a rebuild so going that route. 4 of my injectors i put new o rings on right before i cracked the piston.the truck neve ran with the new o rings but the injectors were installed. can i use them in the new long block when i put the injectors in? trying to sell off my old motor in the classifieds try to get some money back from this sintuation lol. but i guess its all part of gaining experience. o also can i bring my PCM top the dealer.... nopt in the truck for them to reflash it? that may be a stupid question but i dont know the answer.

Chit, that is low mileage for an engine failure. I doubt the dealer will reflash a PCM unless it is in a truck as I am pretty sure they use the OBD port for that. Might want to call and check. I know Jody can do it though.

I got scared of hydro-locking mine, so i went and took the heads off, and drilled drainage holes in all 8 pistons just in case....
I must have knocked something though, cause it seems to be running funny now...

Hydro lock is when there is liquid in the cylinder and as the piston comes to TDC with the valves closed, the piston tries to compress the liquid. Since it can't, something has to give and in this case it was the piston. Many times it is the rod bending.

The rod would probably not bend, as a PMR would sooner shatter instead of break. Its like trying to bend an aspirin, it would break before it bent. If you want to check, put a straight edge on the fire deck, and rotate the engine until that cylinder comes to TDC. It should lift the straight edge up a small amount, usually .030 or less. The piston actually protrudes from the block.
