List of Ford Interference Engines. A list of Ford interference engines includes engines built from 1981 to 1995 with pistons close to the intake valves. If the timing belt broke, the pistons bent the intake valves and disrupted the timing of the camshaft and crankshaft.
How do I know if my engine is interference or 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.

Is a Ford 3.5 an interference engine?
I believe all of the Ecoboost engines are interference engines, but rely on a timing chains rather than a belt for durability. That said, there have been reports on the earlier 3.5s having some instances of timing chain stretch, leading to a noisy engine, but I’m not aware of any breaking or causing damage.
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.15 мая 2018 г.

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.
Why do interference engines exist?
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. … Nothing runs into anything, and you just need to replace the belt or chain.
How long do timing chains last?
In a well-maintained engine, a timing chain can last up to 300,000 miles or even longer.
What does an interference engine mean?
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.

Do Fords have timing belts?
Timing belt and chain replacement is one service that isn’t going away any time soon. Most Ford engines with overhead cam timing belts have a recommended replacement interval of 60,000 miles to 120,000 miles depending on the application (see the chart on page 54).
How do you tell if valves are bent after timing belt broke?
If the camshaft will not turn at all then you have either bent the valves or you’re attempting to rotate the camshaft independent of the crankshaft. The difficulty comes in to play when the valves can no longer open further because they’re hitting the pistons.
