Non interference engine!

[Firestar_3x]

Regarding Cambelts and the such, according to several sources the 1.8 lump in my MX is non interference by design, so if the cambelt snaps I just get stranded someplace and don't wreck the engine, can anyone else confirm this?

Thats the general idea, MR2's are the same but still dont think its worth the risk.

Funny you should say that mike, i just googled your mr2 before you posted

The reason for this is that every 60,000 miles, Toyota recommends a cam belt change for the car and this is an engine out job. A Toyota main dealer can undertake this job for around £400. Fortunately the MR2 engine is whats known as a non-interference unit, so even if the belt does go, your valves wont collide expensively with your piston.

Great engine design tbh, just an extra safety net i suppose

Reason i'm asking is the MX is a 99 on a V, mazda recently revised the cam change interval to 53k or 6 n a bit years, its coming up for a cam change soon but i was wondering it i could wait till its next service and do it all at the same time, its just had a mazda main dealer service 600miles ago.
