The chain really loosens (stretches) a lot with wear. As do the chain guides. These factors, combined with a worn tensioner, can lead to the chain becoming so sloppy it shears off. I've heard of it happening to several people. Updating the tensioner will prolong the time before the chain and rails need replacement though. You're right; the timing chain issue is a bit overblown. The tensioner is really the critical item.

I must admit, I am becoming more inclined towards your thoughts Stan. I have still to meet or hear directly of someone who's chain has actually broken. I think the tension is the thing, if the chain is that sloppy it jumps teeth then wave by by to loads of cash to sort out bent valves, re-profiled pistons etc. I suppose the other thing is that if the sprockets get worn then they could be just as likely to cause the same problem even with a nice taught chain.

..tensioner as required. S14s are not known for chain breaking. Keep the tensioner in good shape, go with later improved versions and the chain and related bits will last and last. IMO the chain issue is overblown by some.
