The Pontiac 2.4 liter engine, is not and interference engine. The Pontiac interference engines are all larger than 3.0 liters.
the 2002 Pontiac Montana came with a 3.4L engine.
A 2004 Pontiac Montana has an interference engine with very tight tolerances. These engines will suffer catastrophic failure if the valves and pistons are not in perfect sync.
Most do not, but some do. If you had listed what engine you are asking about I could give a definite answer. Some 1.5L, 1.6L, and 1.8L Diesels are interference. Also some 3.4 L V6 are interference.
Yes, the 1.8-liter engine found in the Pontiac Vibe is considered an interference engine. This means that if the timing belt or chain fails, the pistons can collide with the valves, potentially causing significant engine damage. It's important to maintain the timing components to prevent such failures. Regular inspections and timely replacements are crucial for engine longevity.

After looking at the Gates website ( they make timing belts etc. ) I found ( 3 ) 1989 Pontiac models that were available with a 2.0 L engine The Grand Am , Lemans , and Sunbird and NO , IT IS NOT AN INTERFERENCE ENGINE
Yes, the engine in a 1998 Pontiac Sunfire is considered an interference engine. This means that if the timing belt or chain fails, the pistons can collide with the valves, potentially causing significant engine damage. Regular maintenance of the timing components is crucial to prevent such failures.
Interference,
Interference engine.
This engine uses a cam chain and no maintenance is required.THIS ANSWER IS TOTALLY INCORRECT OK FIRST OFF IT DOES HAVE A CHAIN THAT WILL BREAK AND YES IT IS A INTERFERENCE THE GM MANUAL SAYS IF THE CHAIN BREAKS TO CHECK FOR BENT VALVES.
