When a broken belt will cause severe damage. It's my understanding a non-interference engine will Not have as much damage when a belt breaks.
Honda Q&AAsk Your Question
2003 Honda Accord Question: Why does Honda keep making an interference engine?
Answer #1pushrod October 29, 2012, 08:27Master
GOOD QUESTION. I WOULD LIKE TO KNOW ALSO. SINCE OTHER ENGINES PERFORM AS WELL AND ARE JUST AS DURABLE.
NOT JUST HONDA EITHER. NOW ANY ENGINE IN THE RIGHT CONDITIONS CAN IN FACT HAVE INTERFERENCE WITH VALVES AND PISTONS IF IT GETS OUT OF TIME. WELL MAYBE A FEW EXCEPTIONS.

Technicians answer: To teach consumers to perform preventative maintenance
Consumers answer: To keep auto shops busy
Automotive Engineers answer: To get a small engine to deliver the power and performance of a large engine while reducing emissions and improving gas mileage

Have you ever seen the converter set-up on a rotory engine? Insane for the actual displacement.Alex , I'll take answer #3- Engineers are catering to what the public is being 'programmed' for, POWER- and for that you must sacrifice something. I believe it was ferrari , back in the '70s had a near zero-emissions V12 , but it had no lower-end torque power band was somewhere starting over 7000RPM red line around 13K. All valve train related , no smog controls (EGR , A.I.R. ,or converters).

the idea of closer tolerances is due to preformance and smog but they could have put a chain like most do now.

OK got all the answers. It's still as clear as Mud!! There's a lot of cars out there that get very good mileage, perform well, have low emissions, and non interference engines. I never claimed to be a genius, maybe I'm just stupid, and you can't fix that. Thanks for all the answers!!

Wetry is ok in my book too, if I wasnt a technician I would let him fix my cars. I would even buy a Honda!

I HAVE NOTHING AGAINST HONDA IN FACT I THINK IT IS A FINE CAR. I JUST WONDER WHY SOME MAKES ARE INTERF. AND OTHERS ARE NOT WITH EQUAL PERFOFMANCE IN EVERY WAY! BUT THIS COULD GO ON & ON SO I GIVE UP.
