on vehicles? maybe the timing belt lost teeth or isn't tight enough due to a failed or failing tensioner.
No. A worn timing chain or belt would cause timing to jump.
sorry i cant understand your question. But i am guessing you mean what is the timing jump? WEll it is a type of jump! daaa by lilianna Simpson
Why would a timing belt jump time and cause damage to the cylinder heads ?
The timing belt can only jump time if there is a failed component in the timing belt system. Check the pulleys and tensioner.
Timing chain or belt is broken
Worn timing chain.
Yes, if the timing chain or gears are worn, acceleration can cause the chain to jump.
Possible but probably not.
Loose timing chain or belt.
I would suspect you need a new timing chain or belt depending on which is installed. A worn belt or chain will jump time.
A sloppy worn timing chain.
If you have a worn timing chain that hasnt been changed before, that can cause the timing to jump and cause your car to run very rough or not run at all
