Does my car have an interference engine?

You can check to see if your engine is an interference type or not by going to http://www.gates.com, and click the “Aftermarket” tab. Under “Cars & Light Trucks” section, click “Belts, then click “Timing Belts.” Click the link that says “Got an interference engine? Find out now” and chose your vehicle and engine.

Is the 2.0 Zetec an interference engine?

The Zetec IS an interference engine, give that regular pistons will hit the valves. However, the Zetec ACTS as a freewheeling engine, given that Ford put recessed pistons in the engine to give the valves clearance to be fully extended and the crank can turn without the cams without damage to the pistons or valves.

What cars have interference engines?

Do I have a non interference engine?

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.

Are interference engines better?

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. These designs extract more power, use less fuel and generate fewer emissions.

Are interference engines bad?

In interference engine designs, replacing a timing belt in regular intervals or repairing chain issues as soon as they are discovered is essential, as incorrect timing may result in the pistons and valves colliding and causing extensive internal engine damage. A very large valve gap points to a bent valve.

What happens when an interference engine jumps time?

In many cases a jumped timing belt will cause some engine damage. A timing belt can also strip teeth off, shred, or break entirely. On an interference engine this will cause engine components such as valves and pistons to collide which is every bit as bad as it sounds.

Will a slipped 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 causes an engine to jump time?

The most common cause of timing chain stretch is lack of maintenance and regular oil changes. Worn out oil can no longer lubricate the chain and will cause the rollers and links to wear against each other. As the timing chain wears, this can change the timing of the camshaft and crankshaft.

How do you fix a engine that jumped timing?

There is no easy way to correct a jumped timing belt. You will need to disassemble a portion of the engine to gain access to the belt tensioner, so you can move the belt back into position. I suggest replacing the belt and tensioners while you have it apart, so you don’t have this problem again.

How much does it cost to fix a jumped timing?

For most cars, a timing chain replacement costs between $413 and $1040, or you can order the parts themselves for $88 and $245. It is a tricky repair though, so unless you’re particularly skilled it’s usually best left to a mechanic.
