lol as if, k12 and QG timing chains are cr*p nissan blame poor servicing something on the lines of this "the escaped combustion gases over a period of time induce excesive wear on the timing chain" bascially in lamens terms the chains are no good and are prone to stretching (elongating)
i can get the bulletins and post them up if people dont believe me.
the main expensive problems on k12's are:
timing chain stretching
valve seats burning out
