when i take the timing belt off and turn over the engine the piston seems to get stuck at the top and bottom. is this because i have bent valves? any help would be great because i dont want to take them out if its some other problem.

 

 

You should not rotate the crankshaft without the belt in place...
Depending on what position the cam is in,there are most likely valves
being held open by the camshaft..

 

well thats the only way of timing it... anyways is there a way to see if the valves are at the top since i can never seem to place the cam sprocket in the right spot does it go straight up or perpendicular to the cylinder head?

 

give us alittle bit more info like when u say stuck does this mean it gets harder to turn the crank when there at tdc and bdc?

 

it gets completely stuck and the only thing i can do is turn it the other direction

 

sounds like ur motor is shot (seized up possibly) i would take it apart and see exactly what is up inside of the head and block...good luck
