Hydrolocked my motor

Could do a compression check and maybe narrow it down to a cylinder. Then pull that head and if the problem is in the head you won't have to pull the entire motor. If the head is OK then turn it over and see if the piston is coming to TDC. Got a feeling if you truely hydrolocked it you may have a bent rod and it's hitting the bottom of the cylinder.

80psi coming ont of a garden hose? I think that sounds high but if it's correct I would guess that it pushed past the head gasket and filled the cylinders with water just before starting. I always turn the water on just after starting to avoid static water pressure in the system for that reason and shut the hose down at the same time as shutting the engine down. just saying, 80 psi is alot, IMO. I hope it's good news when you tear it down but it doesn't sound likely. At least its winter. Trying to look for a bright spot I guess.

My hose pushes at least 40 lbs, but wont push water past my raw water pump. It also does not even come close to keeping up with the raw water pump as far as flow. It regularly sucks the garden hose flat at anything over an idle.

I don't want to turn it over any more, and do more damage. I squirted some oil in the Cylinders to hold it over until I pull it out.. I've already made up my mind I'm pulling it.

After pressure testing the Manifolds, and running water through the risers, and finding no leaks, I have to conclude that this was self induced... Too much hose pressure I guess.. God I've done this a hundred times.
I can't imagine that water can go past the pump.. at a higher volume than the pump is pumping. Does that even make sense?
The idea of using the 5 gal bucket sound like the safe bet. Good one, and soon to be my new process
