Im new to this & im unsure what im doing.

I drive a Shogun di.d classic, ive been have mega issues with the engine. It's had 4 timing chains fitted in the last 8 months!!! These chains have been fitted by a reputable garage, on 2 occasions the chain has completely snapped, the other 2 has been becuse the chain was damaged & the nylon guides totally destroyed, the garage has covered the subsequent repairs through warranty but have now told me that if it happens again that they wont repair it.

I luv the car but im getting to the end of my tether with this as you can imagine, im unsure of what to do next, when it initially snapped i had contemplated putting a reconditioned engine in it but went with the repair. The garage was confident that it was fixed completely but it broke again after about 2000miles.

Does anyone have any ideas of what could be causing this as everyone i've spoken to does not believe that it would be possible for this to happen so many times.

Any imput welcome
