JASON: Dustin what are the signs of a faulty engine? DUSTIN: Oh jeez, it can get real scary sometimes you hear a knock knock knock knock or click click click click click click! Or you're driving down the road and you smell something funny, you know or you see smoke, which is a big scary scenario when you want to pull over immediately. Or if you see an engine light start flashing, that means pull over right away, because you don't want to cause any more damage. Or if your vehicle's overheating, you want to pull over immediately, shut it down and call for a tow truck, or call somebody for some expert advice. JASON: Awesome! Thanks for the answer!
