There are a substantial number of overhead engines that
are non-interference. The four cylinder Toyota Camry and
many of the other Toyota/Lexus engines are non-interference.
I understand that the interference engines were designed that way in order to get more power and increased efficiency.
Honda switched to a chain, probably from many complaints from owners that failed to change the belt when required.
As long as the belts are changed at proper intervals, it
doesn’t really matter if the engine is interference or not.
And timing chains will stretch over time and their replacement is a lot more work than a belt.
How do they get the compression for needed fuel efficiency without being an interference engine? The Camry 4 cyl is 10.4:1 compression.
As long as you make sure you keep the oil at the proper level, you should never have to replce a timing chain; or least not for over 200,000 miles.
