Can a non interference engine Bend valves?
non-interference engines. A non-interference engine provides clearance between the valves and pistons, so if the timing belt breaks, you might end up with bent valves, and you might have to have your cylinder heads rebuilt, but the engine isn’t likely to be destroyed.
What Ford engines are interference?
Interference engines made by Ford include its 1.6-liter single overhead cam engine, 2.0-liter double overhead cam engine, 2.2-liter engine, 3.0-liter single overhead cam engine and 3.3-liter engine. Ford’s interference diesel engines include 2.0-liter, 2.3-liter and 2.4-liter units.
How do I know if I have 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.
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.
Can a broken timing belt cause bent valves?
Interference vs. non-interference engines. The level of damage caused by a broken timing belt can depend on the type of engine you have in your car. A non-interference engine provides clearance between the valves and pistons, so if the timing belt breaks, you might end up with bent valves, and you might have to have your cylinder heads rebuilt,…
When did the timing belt break on a Ford engine?
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.
What happens if the timing belt snaps on a Ford Escort?
Fortunately for many Ford owners, there is enough clearance between the valves and the pistons so no harm will come to the engine if the belt snaps. But on older Escorts (up to 1985) with 1.6L engines as well as 1989 and up Probes with 2.0L or 2.2L four cylinder engines, a timing belt failure will usually bend a bunch of valves.
What happens if you neglect your timing belt?
Now you know the disastrous consequences of neglecting your timing belt – engine valve and piston damage, bent valves, cylinder heads that need to be rebuilt or replaced, and possibly even total engine destruction. If you don’t want to see those dollar signs adding up, check your timing belt regularly,…

When to change timing belt for interference engine?
It may last until 80,000, 90,000 or even more miles before it fails. But eventually your timing belt will fail, and when that happens it can cause expensive engine damage if your engine is an interference engine. If you do not know when your timing belt should be changed, look up the recommended service interval in your owners manual.
