Our son recently killed his car. It was runinning fine and quickly got hot and stopped. We were told that it may be head gasket, but there is no water in oil and it wont crank. We were also told that the timing may have jumped. How do we determine the problem and if it is the timing what parts are needed to repair? 2nd opion mentioned a plastic peice in the timing peices that may have snapped. Does any of this make scence to you?

It sounds like the engine has siezed. The pistons may be siezed to the block, or the crank. Or the camshaft could be siezed. As far as plastic pieces breaking off to cause this, if you have an overhead cam, it may be. But I think the 94's has a overhead valve 4.0. Even if the timing jumped, it would have caused engine damage by allowing the pistons to smack the valves. You can try to use the crank pulley and turn the engine backwards to see if it is frozen. If it is a timing issue, you may be able to move it. If the engine is toast, it won't budge. Either way, your best bet now is to pull the heads and check for damage. Let us know if you have more questions.
