Default What cars have interference engines?

What are some cars that have interference engines? Just curious if they are common in one brand or if it's a hit and miss type thing? Also what precautions do you have to take when working on one?

Wrong. Toyota 22R is most definitely interference.

I don't care if it's a rope. If the pistons hit the valves when whatever is connecting the camshaft to the crankshaft breaks, THAT is an interference engine.

As is the 944 and 968 4 pot. I looked for a picture I have from my old 944 that aptly demonstrates it

That's a neat list but it doesn't have anything in the 2000+ years, is it just out of date or are no newer cars interference?

This is an interesting subject, every engine I've ever heard of breaking a belt/chain has at least kissed a valve, I was under the impression that interference valve gear had been almost universal for many years.
We live and learn.

That's a belt manufacturer's website, therefore chain driven motors are not listed (as far as interference goes).

I do not know if there are non-interference motors with timing chains, though. Does a chain always mean interference?

Not necessarily.

Unless you need a full list of every engine, it's probably simpler to just google on the particular engine you're working on at the moment.

So it's "fairly" safe to say most newer cars are interference engines?
