I am having the Aux belt, cam belt and oil change done on my 182 at k-tec on wednesday. The car appears to be running rough at the moment, ticking noise coming from engine, not LOUD but enough to be noticable. Also from around 2,750-3000 rpm, the ticking noise re-appears, just sounds rough. I have my fingers crossed the service will sort it. Anyone had any experiance of these problems. Dont want an already expensive service to escalate any further! Any advice is much appreciated.
