Cranks wont rotate fully. Stuck Valve??

[rwcoop]

I have just bought a turbo engine second hand and when I time it up the crank rotates round and stops in the same place each time. Is this just a stuck valve and if so, whats the easiest way to fix it.
It had no plugs in it when I got it so am a we bit suspiciouse that sumthing has fallen in the bore. Thats what it feels like but im sure this is unlikely. Is this the sort of symptoms of a stuck valve??

If you can't see something in the bore or feel it with some kind of tube or whatever to explore with then pull the heads. These engines are non-interference and stuck valves are rare anyway. I'm not sure if the valve could ever hit the piston, especially with the turbo.

if you have put plugs back in, take them out and check that each cylinder is empty - transported engines can be turned every which way, and cylinders can fill with oil which will cause your symptom

argh! i remember turning over an engine that was filled with oil to keep it from seizing.. quite the unexpected oil bath! lol.
