What does an interference timing chain mean?
Interference engine means that the head valves (head of the engine) goes into some part of the piston chamber, so if the timing belt breaks and the valves are in the inside of the piston when this happens, then the piston can hit and bend those valves as the valves will not return to the safe distance position, which …
How to know when your timing chain has jumped?
1 Noise – A good indication that a timing chain has jumped is going be noise. 2 Performance Decrease – The engine timing is going to be affected when the timing chain jumps. 3 Service Engine Soon – Your vehicles ECM may or may not have enough input from the engines sensors to detect that the timing chain has jumped. But, it often does.
What happens when your truck engine jumps time?
If you have a non interference engine you will need to find the component that caused your engine to jump timing. In the case of a timing chain engine this could be from a stretched chain or a worn guide. There is also the possibility of tensioner failure on either timing belt or timing chain engine.
What happens when the timing chain breaks on a Mazda?
If you can find a local car breaker with an old replacement engine that doesn’t look obviously past its sell-by date, that would probably be your cheapest option. If the chain jumped or broke while turning the engine with the starter, what could happen (if you are unlucky) is that a piston hits and bends some valve.
Why does a timing chain have a tensioner?
It ensures that the piston is close to or at top dead center at the moment of combustion. If a valve is open or the plugs don’t fire at the right time the air and fuel that have entered the combustion chamber are not going to ignite. Most timing chains use a tensioner to keep them tight and to keep them from jumping.

How much does a broken timing chain cost?
So I am happy and looking forward to getting my vehicle back. I then get the nightmare call from the service department Mr. Joseph your engine sustained damage from the broken timing chain and your engine will have to be replaced at a cost of $9800.00.
What happens if your timing belt jumps teeth?
If it’s not an interference engine, the timing belt can jump teeth without major damage, but an interference engine (where the valves and pistons take turns occupying the same space) will be damaged or destroyed.
