What does it mean if a motor is interference?
An interference engine is a type of 4-stroke internal combustion piston engine in which one or more valves in the fully open position extends into any area through which the piston may travel. By contrast, in a non-interference engine, the piston does not travel into any area into which the valves open.
Is an interference engine good?
Most modern engines are interference engines for several very good reasons. In comparison to non-interference engines, interference engines “breathe” better because the valves can open earlier, close later and open wider. Interference engines can also achieve higher compression ratios.
Is my motor interference?

How do I know if my engine is a non interference engine?
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 5.7 Hemi an interference engine?

Is the ABA VW motor an interference motor?
yes it is an interference motor. if it were a non interference the valves would never meet the pistons no matter how hard you ever pushed the motor when the chain broke. the vw aba 2.0 (came in mk3s) as is the 1.9 that came in some ford escorts, is a true non interference motor.
