What is an interference engine to a timing belt?

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.

What is the result of a broken timing chain or timing belt to the interference engine with that of free running engine?

So, if you have an interference engine and the timing belt fails, the camshaft is not turning, and the valves will not open. The piston will still rise into the cylinder and then it will collide with the closed valve. This could damage the cam heads, the valves, the pistons, and essentially destroy your entire engine.

How do I know if my engine is 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.

What are the symptoms of a bad timing belt?

5 Signs and Symptoms of a Failing Timing Belt

Dropping Oil Pressure. One of the worst things that can happen if your belt fails is for the oil pressure in the engine to drop.
Misfiring. Misfiring is a common occurrence with failing timing belts.
Rough Idling.
Smoke.
Broken Pistons or Valves.

Will a broken timing belt destroy my engine?

If a timing belt breaks, the engine will no longer work. This may result in a heavy damage to the engine with broken or bent valves, damaged pistons and, possibly, destroyed cylinder head and block.

What does a 2.0ltr timing belt do?

The 2.0ltr in both single and double-overhead-cam configurations are interference engines. The valves and pistons occupy the same space. The job of the timing belt is to keep everything moving in the proper time so the valves and pistons are NOT in the same space at the same time.

Why do I hear a noise when my timing belt breaks?

From sheer inertia – no matter how fast you were going or even idling – the crankshaft will continue to move the pistons up and down for a short time and will hit the valves. Most likely, a few if not all valves will be bent and typically, you will not hear any type of noise associated with that.

What should I do if my timing belt broke?

Most likely, a few if not all valves will be bent and typically, you will not hear any type of noise associated with that. The most cost effective repair would be to install a rebuilt cylinder head.

When to know if your car has an interference engine?

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. Not so with a non-interference engine. It pays to know. The video below will also help you determine if your car has a timing belt or chain.

Most likely, a few if not all valves will be bent and typically, you will not hear any type of noise associated with that. The most cost effective repair would be to install a rebuilt cylinder head.
