Beside above, 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.

Considering this, what engines are interference?

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.

Is the 2jz an interference engine?

The 2JZ is not interference, even the HKS 264's have low enough lift to clear. JUN and other brands are potentially high enough to hit so be weary.

Will a broken timing belt destroy my engine?

Will a Broken Timing Belt Destroy My Engine? It depends. Some cars, like Subaru, have non-interference engines, which means that if the timing belt breaks while you are driving, there is no damage to the internal parts of the engine. Most timing belts need to changed between 80-100K.

What happens if a timing belt breaks on a non interference engine?

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 happens when engine timing is off?

If the timing is off, damage can occur. In some engines, called “interference engines,” the consequences can be especially bad. You could end up having to have your engine rebuilt, or even replaced. If your cam timing is off, chances are you'll know because your car will not be running well, if it's running at all.

What happens if a timing belt breaks while driving?

If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position. This may result in a heavy damage to the engine with broken or bent valves, damaged pistons and, possibly, destroyed cylinder head and block.

Which Subaru engines are non interference?


SUBARU vehicles manufactured up to and including 1996 typically non-interference SUBARU engines. The 1996 2.5L phase I DOHC engine is likely non-interference piston to valve, but interference between intake and exhaust valves.

Are interference engines better?

Most modern engines are interference engines for several very good reasons. 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.

Are all Toyota engines non interference?

All the vvti engines are interference engines, which is why Toyota moved back to chains instead of belts. The 3MZ and vvti 1MZ being notable exceptions. 1MZFE is not interference with or without VVT-I.

Can a timing belt last 200 000 miles?

Your owner's manual is a good resource and will indicate the mileage interval recommended for your specific vehicle make and model. Depending on the manufacturer of the vehicle, mileage ranges for recommended timing belt replacement is anywhere from 60,000 miles to 100,000 miles and 6-10 years old.

What does SOHC mean?

Single Overhead Cam

Why does Honda use timing belts?


The timing belt is what allows the crankshaft to drive the camshaft, which opens and closes the valves, and without it, the engine can't run. For this reason, changing the belt when recommended is crucial to your Honda's maintenance.

How do you know when timing belt needs replacement?

When to replace the timing belt? Unfortunately, in most cases, there are no obvious signs the timing belt is near death; it will just break. That's why highly rated auto mechanics recommend replacing it every 60,000 to 100,000 miles. Always check your owner's manual for the manufacturer's recommendations.

How do I know if my timing belt is going bad?

Check out these symptoms of a bad or failing timing belt
  1. Ticking noise coming from the engine. The timing belt is attached by way of a series of pulleys to the engine's crank and cam shaft.
  2. Engine won't turn over.
  3. Engine misfires.
  4. Oil leaking from in front of the motor.

Are boxer engines interference?

The SOHC EJ Subaru boxer engines were non-interference engines through 1996, run by a single timing belt driving both cams (both sides of the engine) and the water pump. Because they are non-interference engines, if the timing belt fails, the engine of the models up to 1996 will not be destroyed.

Why do they make interference engines?

It broke while the engine was running, so the pistons are in motion. Because the timing chain/belt is broken, the valves aren't moving, which means some of them are stuck in the open position. If the piston travels far enough in the cylinder to actually hit the open valves, that's an interference engine.

What year Toyotas have timing chains?

4Runner 1990-2000,2010 4 Cylinder
Avalon 1995-2004 V6
2005-2012 V6
Camry 1990-2001 All
2002-2012 4 Cylinder

Can low oil cause timing belt to break?

If the tensioner has no oil pressure, the belt will become loose and possibly disengage from the pulleys and/or break. Additionally, if the camshafts don't have enough to operate properly, they will lock up, which can cause the timing belt to break.

Does my car have a timing belt or chain?

There is an easy way to find out if your car is driven by a timing chain or timing belt motor. If, on the side (not top) of the engine, either left or right, there is a plastic cover, your car has timing belt. If there is no plastic on the side, you have a timing chain.
