My old man has been trying to replace our timing belt. And he almost had it timed everything was turning, he went to bed got up went back to it and now the crank is hitting the rod cap bolts. How do I fix it and why did it do this when it was completely fine the first fifty times he tried?
Do you
have the same problem?

There is a small hole in the cam gear that will align with a mark on the timing cove, this it the cam alignment mark. The crank gear has a notch and alignment mark at TDC, align both these. See picture for cam position information.

He knows that, he is trying to hand turn the pulley and it is hitting the rod bolts keeping it from turning a full 360 degree rotation. The valves are fine.

No it was just slapping. How could he drop a valve when it was running when he started this project? How do you tell for sure if the valve dropped? Do you have any pictures of a good valve verses a dropped one?

The 2.2 is an non interference engine, if you have a lock up then something is very wrong. Have you got the plugs out? Are you sure there is no damage in the valve train? I know it is hard to see, but there should be no reason that the cam cannot rotate freely.

No pictures that would be off assistance, you may have to lift the cam out and do a visual inspection of all the valve heights. Make sure that you mark the cam caps and direction they sit and the order they sit in as well.

Okay, sorry, my mistake, if the crank will not rotate and you are hitting something, you can do a simple test that may show something. Pull the plugs and place a long thin screw driver into the bore so it touches the piston, try rotating until it stops. If you have a rod blown out, one of the pistons will probably not move as far as the others. It is a bit of a hit and miss, but it is something you can try with out dropping the sump off.

Okay, he is going to look. I do not understand how it went from being able to hand turn it one night but then it stop turning next morning? He said only thing he did was unscrew one bolt that he thought was the tension-er.

Nothing on the front of the engine that will cause that, just the tension-er there and the oil pump is behind the engine crank pulley. Very strange indeed.

Okay it is the rod cap and rod bolt catching just before it completes a full rotation. What causes that? And how do we fix it? Please I am desperate.

Chances are you are hitting the valves, there is nothing that will stop the crankshaft from turning in the block.

Please let us know what happens, we are interested to see what it is.

OK this is what happened, the motor mount on the top right is bad and he had removed the jack from under neith and when he did that made the motor shift by a hair now making the rod cap hit side of the block. That's what caused it
