I agree with you, Doug.
My first reaction to the original question was that all diesel engines, by the very nature of the high compression needed for ignition of a diesel, are interference engines. I couldn’t recall any diesels in my experience that used a timing belt instead of a chain or gear train. But I forgot about the Pathfinder Diesel, which is essentially a marineized version of a VW Rabbit engine.

With the compression ratios of diesels I would imagine they are all interference fit engines. Meaning that the valves open into the space of where the piston will be at a different point the the cycle.

A club member had his break recently and it destroyed his engine which he choose to replace rather than repair....and not sure if it actually could be replaced. I'll get more info on the exact type of engine and the extent of the damage. He said some marine diesel engine 'timing belts' can break but not cause the kind of damage his did.
