wankers ... Think you are on firm ground mate, you are selling a used car, not a new car, what the fuck do they expect?? Even if the tappets had to be adjusted, so what? things wear, especially if he has thrashed it or run it low on oil .... not your fault if the garage are that bad they have to take the shotgun approach to finding a fault is it? ...... and why do all that work BEFORE putting it on a code reader to find the relativly minor problem? reeks of incompetence to me.....
