If the timing chain system on the LS3 and L99 motors are the same as the old small blocks, they will just quit running if it breaks. They aren’t interference motors. Your Scion should have the belt changed BEFORE it breaks, or else you risk severe head and valve damage when the pistons slam into them.

What is non interference engine?

Put simply, in a non-interference engine, when the piston is at top dead center (TDC), it will never go higher than a fully open valve; that is, the piston can never “interfere” with the valves. Conversely, in an interference engine, the piston could occupy the same space as an open valve.

What’s the difference between an interference and a non-interference engine?

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.
