How do I know if my engine is interference or non-interference?
If the timing belt snaps, they run into each other, causing bent valves (most common), cylinder head or camshaft damage, and possibly piston and cylinder wall damage. In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs.
Is the Dodge 2.4 a interference motor?
If you have the 2.4 DOHC engine it is not an interference engine and the valves will not be bent. You are very lucky. Replace the belt, tensioner and water pump if it is accessible while doing the timing belt.
Is a 2.4 L engine a non-interference engine?
Re: PT 2.4L is a non-interference engine With the DOHC, each cam controls a pair of intake or exhaust valves per cylinder. The timing belt along with the cam index insures the synchronizing of the cam timing and thus keeps the valves from hitting.

If you are one tooth off it won’t damage the engine, it just won’t run very well. Two or more teeth off, you run the risk of bending valves.
