I'm guessing the chance is close to 0 without some other contributing factor.In that case, I'd be putting this to Ford, get them to explain how it could happen to a car where the chain hadn't jumped.Also, ratter how come the chain jumps? It sounds like it's more common than I first thought? Link to comment Share on other sites More sharing options...

Since then I take my foot of slowly rather than "letting go" of the pedal, it avoids the clunk which sounds and feels crap. Link to comment Share on other sites More sharing options...

What part makes the sound? It always sounded like it was coming from the back rather than the transmission or anything. Link to comment Share on other sites More sharing options...

In all the threads I've seen here, I've seen hardly any issues with Ford HQ, most are with the Dealers. Link to comment Share on other sites More sharing options...

When I asked for it in writing it seems that Nuford alone has decided its not a warranty claim.I also had my mechanic pull out a inlet valve and in the lathe it showed an slight bend easily seen to the eye.
