What happens when engine jumps timing?
An engine with a jumped timing chain will show signs of very sluggish and slow starting. This happens because the firing sequence is retarded due to a chain that has jumped a tooth. A chain that has jumped two or more teeth may not start at all.
Can you fix a motor that jumped time?
There is no easy way to correct a jumped timing belt. You will need to disassemble a portion of the engine to gain access to the belt tensioner, so you can move the belt back into position. I suggest replacing the belt and tensioners while you have it apart, so you don’t have this problem again.
Will a car run if the timing is off?
If the engine timing of the cam is off, your car will either be running rough or not at all. If the ignition timing is the problem, it isn’t as easy to notice because it has four cycles: Intake valve sucks in air while fuel is delivered by the injectors. The fuel mixture is reduced.
What causes a timing chain engine to jump time?

Can a timing belt jump cause an engine leak?
My mechanic is telling that my timing belt was jumped and hit water pump. He did leak test and find leakage in middle 2 cylinders. He wanted to replace the motor. He performed the leak down test using Cylinder Leak-Down Tester as shown in http://www.harborfreight.com/cylinde…ter-94190.html.
What happens if the timing belt breaks on a Camry?
I don’t believe that any of the engine options on that year Camry are interference engines. If the timing belt broke there should be no engine damage as I think all of the dual camshafts on these engines are gear driven under the valve cover. You state that the mechanic said the timing belt jumped.
What to do when your truck engine jumps time?
The fix is to replace the timing set. Depending on the engine this could be gears or it could be sprockets and chain, and may or may not have a tensioner and/or guides. On some engines the gear on the camshaft is pressed on and will involve removing the camshaft to have the new gear pressed on.
