A coworker of mine today threw a piston rod today. We were taking bets as to how much the repairs were. Anyway...the subject of engine types came uptoday and the question was whether or not my coworker had an interference engine or not.

My question is does anyone know if E46 engines are interference engines or not?

What is an interference engine?????
An interference engine is when the valves and the piston head occupy the same space at different times. It's a higher amount of precision that non-interference engines. It improves power but if your timing belt/chain breaks then oh brother, you're ****ed. :eeps:
