chances are it has not been done due to mileage, you can tell by the bolt on the side of the engine
if the rusty old bolt on the back of the engine, next to the timing chain cover hasnt got the little cut outs from the corners, you have the old type oil jet that is prone to block
and if it is the original then it will need replacing as the old style timing kit had various weaknesses
our resident mechanic / member [benny] offers timing chain replacements supplied and fitted for around 50% less than what dealerships charge using OE equipment
