Best Answer

A timing chain or belt is worn so sloppy that it jumps a tooth on the sprockets creating loss of power and performance, jumping more than a tooth would render the engine inoperable and in some cases destroy the engine in an interference engine.

How do you fix the problem of jumped timing with out timing light?

Your question is too vague usually when someone says that their engine has jumped time that means that the timing chain has jumped on the timing sprockets. If that is the case you would need to change them. If the distributor is out of time to do it right you would need to have a timing light. You would need a repair manual for the specifications to fix both of them.
