The one in the wife's car slipped due to the front idler pulley falling apart and bent numerous valves both inlet and exhaust. A broken timing belt will give the same result.....An expensive exercise to fix. Tony

DO NOT ATTEMPT TO TURN THE CAR OVER, KEEP IT OUT OF GEAR SO THAT THE CRANKSHAFT DOES NOT GET ROTATIONAL FORCE OTHERWISE IT COULD CAUSE SERIOUS DAMAGE.You need the services of a mechanic/technician as soon as possible, if we are talking about the cambelt , the engine might be an interference engine which means that times in the engines rotational cycle the pistons and valves overlap. The cambelt, (if that is what you mean by the vbelt,) ensures that the valves are up , away from the piston when it is on the up stroke. It sounds as though your engine might have sustained some damage but this might just be some bent valve heads which can be resolved by replacing valves. Hopefully there is no more damage than this. You really need to find a decent diesel qualified engineer.
pinging in the engine is detonation caused fro wrong air fuel mixture for the accelerator opening and engine load. It is controlled by knock sensors that adjust the mixture in the CPU .IT has nothing to do with valve timing but may be affected by ignition timing . I would be having a compression test done to check for bent valves ( bent during the belt replacement). Have the cam timing re checked as it may be still out a bit.
To answer your question directly......NO, the engine can not rev when the cambelt is removed, it won't even start. This is virtually impossible for any 4 stroke engine.
i will explain why....... The cambelt connects your camshaft with your crankshaft, when the engine was assembled, the camshaft and crankshaft was turned on the correct alignment marks and the cambelt was fitted. These marks on the cam and crankshaft allows the 4 strokes to happen at the correct time(intake stroke,compression stroke, power stroke and exhaust stroke) If the cambelt had to be removed, there will be serious damage done to your engine, in the first place, the car will not start if the cambelt was removed. the correlation between your camshaft and crankshaft will not correspond and the pistons will hit and damage the valves.
It does depend on your engine design. Essentially if there is limited clearance (interference fit) between your piston head and valve then damage is likely otherwise you may be fortunate enough to replace the belt and be on your way. Important not to try to turn the engine over without at belt or the belt not installed correctly as this could cause damage.
It depends a lot on if the engine was running at high revs when it broke...in this case the valves would clash with the piston and cause them to bend or break and all sorts of horrors could happen. If the car was at idle speed, while it still could cause damage to the valves there is always a chance that you could get away with it.
Yes. I think. A lot of cars have the water pump under the timing cover and you change the pump when you change the timing belt. They usually don't seize though, they just leak. Did you run it after it broke? How long before the engine quit? Did it start knocking? When you go to change the belt, look for a broken cam, or other damage that the broken belt would have caused. Some engines are free running, meaning they will turn over no problem when the belt goes, other engines are intermittent, meaning the valves hit the tops of the pistons and cause considerable damage. Find out before you go too far. Hope this helps.
i would say no if it froze then it has poss. cracked the cylinder head and/or block
if the engine locks up then most likely the cylinder has water or ice causing a hydrastatic lock
best advice i can give you is get a used engine
hope this helps
these bend valves if belt breaks while running
Align the timing marks on the camshaft gears to the notches on the camshaft cover, using the intake gear mark for the intake gear and the exhaust gear mark for the exhaust gear.
Align the mark on the crankshaft gear with the
notch at the bottom of the rear timing belt cover.
you mean the timing belt..well you can bent your valves if your not lucky mostly engine running with interferance ingine but yea if your timing belt snap it can damage your valve timing belt should be change at every 60k miles or suffer later..
