I have a problem: the timing belt cannot be properly tightened, the left side is tight and the right side is quite loose. If I want to turn the timing belt tensioner on “new”, the right side is still loose and if I want to further tension, the tensioner jumps up again. After I wanted to turn the motor through, so that the loose side direction tensioner comes, I had to find that the motor can no longer spin, which is probably the valves are the a And the worst thing is now the OT position of the crankshaft can no longer be seen because the belt disc had to be dismantled. The camshafts are now on the end-speaking notches but the crankshaft no longer fits. How can I turn the crankshaft right now, through a screwdriver in the candle hole of the 1st cylinder?
