Toyota 20R, 22R, 22RE, 22RET, 2RZ-RE, 3RZ-FE engines are all chain driven interference engines. The 5VZ-FE and the 3VZE is a belt driven non-interference engine. Therefore the valves can not come in contact with the pistons if the timing is not correct.
How do I know if my engine is non interference?
The difference between an interference and non-interference engine is whether there is a gap between the valve that is fully open and the piston that is in the top position. If there is a gap, the engine is called a non-interference engine. If there is no gap, it is an interference engine.
What is the difference between a 22R and 22RE motor?
The 22RE was the fuel-injected version of the 22R. The engines remained in production through 1995. A turbo version received a 22RET or 22RTE designation, but only saw production from 1985 to 1988. The 22REC denoted the engine met all California emissions requirements.
Why is the 22R engine so good?
Although a turbocharged version was available, the long-stroke 22R and 22RE are at their best when operated as low-power (right around 100 horses), task-focused engines that deliver good low-end torque (thanks to their long stroke) and fuel efficiency for their size.
Are Toyota engines interference engines?

Is a 1.8 t an interference engine?
The 1.8T Jetta is an interference engine (a.k.a. non-clearance engine). … Close tolerance engine designs allow for the cylinder head valves to hit the top side of the pistons. VW Jetta timing belt failure on these engines will results in catastrophic engine damage (i.e. bent valves and in some cases cracked pistons).
What is the difference between a interference and 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.

What is a non-interference engine in a Toyota?
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 is a Toyota interference engine?
Interference Engines – Complete List. … An interference engine is one that has insufficient clearance between the valves and pistons if the cam stops turning due to a broken timing belt. The result is usually catastrophic engine failure.
