What happens if the chain jumps on a Mazda?
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. The piston would probably survive. If so, it would not be quite as expensive to fix as you have been told.
What kind of engine does a Mazda 3 have?
I have a 2007 Mazda 3 2.3L with about 155k km on it. I was attempting to replace the AC pulley bearing, and had to manually turn the crank pulley to get the belt back on the AC pulley. After making sure the AC pulley was tightened, I started the engine to see if the AC worked.
Is it worth it to replace timing chain?
If the chain broke the actual damage might be minimal. Depends on how expensive a new chain is, but it could be worth it to just replace the chain, re-align and see how the engine runs. Doing an (2nd hand) engine replacement will still be available as a last resort. (For a 155.000 km engine a rebuild just isn’t worth it.)

Once you get the crank on TDC with #1 piston at the top of the stroke and line up the cam gear on position A that pin will line up with the pin it’s supposed to lock into. Those other letters are for other reasons , they might be set differently on a different engine that uses that same sprocket i think or maybe some other engineering purpose.

When did Mazda stop using the timing belt?
There are plenty of Mazdas equipped with timing belts still on the road and this can spell service opportunities for your shop.

Why is my timing chain making a noise?
With timing chain engines, the most common complaint is noise from the stretched chain or variable valve timing actuator. Or, you may see P0011 or P0012 DTCs, indicating the cam timing is not as expected. This code could be as simple as the oil level being low, but it could also be the result of a worn chain or actuator.
What do I need to adjust the timing on my car?
Your timing must be at the correct setting for your car to perform at top level, affecting the speed and efficiency at which the engine fires. You can adjust your car’s timing with a timing light and a set of wrenches, tools available at any auto parts store.
