Is the American turbo engine an interference engine?

I can hear the groans already, given that this thread goes back more than a decade, but a San Diego guy is shopping for an M100 and has seen conflicting opinions online.

If the cam belt breaks, does the American turbo motor break?

The only thing I see in the Lotus Service Notes for the model is in the Precautions section in "EC.4 - CAMSHAFT DRIVE BELT", to whit: don't rotate the crankshaft or camshafts with the belt removed or damage may be caused to the valves and pistons. (This has been previously quoted in this forum.)

Thanks,

Dave Ellis

PS: Being a belt and suspenders guy, I just had the 120K service (including cambelt) done on my car, at 98,000.

Update: after some more searching I found the "Timing belt" topic which provides the answer...from years ago. Thanks to Brit-Car-Nut, among others. -Dave
