Wednesday, October 01, 2014 List Of Interference Engines
AGCO Auto Quick Tip:

In interference engines the valves and the pistons actually occupy the same place in the cylinder, just at different times. This is done to enhance performance, but if timing is interrupted, damage occurs. 

List Of Interference Engines

Millions of engines use timing belts.  Some are interference engines and if the belt slips or breaks, engine damage normally occurs.

This broken timing belt cause the engine to fail

The following is a list of popular Domestic and Asian engines and whether they or interference type or not.  Under the wrong conditions, any engine that jumps timing may be damaged.  This applies to engines with a timing belt and engines that use a timing chain.   Please consider this a guide only.
