With the timing belt off is the crankshaft still locked?

hi James ,Sorry for not getting back sooner but couldn't access the service.
anyway yes the the crankshaft is still locked after the I took off the timining belt
Expert:  James replied 2 years ago.

If it stops turning that makes it sound like the crankshaft or a piston is bent? Did the engine get hot when the water pump failed?

Customer: replied 2 years ago.
it got hot several times but was still running when I changed the water pump after re assembly it cranked a couple of times then jammed so I assumed I must have knocked out the timing so I went to reset the timing on removing the plugs I noticed there was a lot of oil on them they had actually been sitting in oil up to the porcelain level so I removed the rocker cover and noticed a split in the gasket so all the oil that was sitting in the plug recesses must have gone straight down into the cylinders so now im suspecting a hydraulic lock. what do you think? head removal and see?
cheers graham
Expert:  James replied 2 years ago.

If you have a hydrolock removing the spark plug will allow you to get around it. If the engine still won't turn with the spark plugs out I would remove the oil pan. I think something bent and removing the oil pan will help you find the issue.

Hi James,
just had a quick thought I have removed the camsshafts and all the intake valves are still open, these engines don't have pushrods do they if their overhead camshafts, so perhaps ive bent the valve stems?what do you think?
Expert:  James replied 2 years ago.

It's possible but if you rotate the camshaft a to a neutral position the crank should rotate. If a valve is stick open the piston can just be locked against it without actually causing any damage. This engine doesn't have pushrods either you are correct on that as well.
