still soak the cylinders? then try breaking them free?
or do you think I should continue soaking the cylinders with the head on by pouring diesel into the spark plug holes and wait? and avoid taking the head off all together? |
If the pistons are frozen then the chances are good that the valve train is too. You'd best remove the head, inspect it and the valves for damage/pitting, then soak the cylinders until you can hand-crank the engine. Don't overdo the force in hand cranking as you'll risk damaging stuck valves as well. Once everything is moving, you can have a good look at the cylinder walls and decide at that point whether it might be better pulling the engine and sending it out for a rebuild... which may well be what's needed; if there's damage in the upper end, it's most likely the crank needs inspecting/grinding/new bearings as well. Better to do it now while you're in rebuild-mode!
