From what I understand the 2JZ series of engines are all non-interference.

Jacob, It's interference and noninterference. Noninterference means if the timing belt breaks then the valves won't hit the pistion. Obviously interference is the opposite <_<

wait, if your timing belt breaks... how would that cause the valves to hit the piston? does it allow the valves to go out of timing?

so for interference, even if the belt breaks, it won't cause the valve to hit the pistons?

[ColinBarber]

The timing belt keeps the crank and cams in time with each other so yes if the belt breaks the valves go out of time with the pistons.

Interference means the valves and pistons can touch each other and non-interference means they won't.

Nearly every Toyota engine that uses a belt rather than a chain is non-interference.
