Okay, so when i drive in the city everything's fine but when im on the highway and i take it passed 65 mph for like 45 seconds or more, the engine starts to smoke, you really don't notice it until you've come to a stop and you see the smoke coming from the wheel arches. But last night i stopped at a gas station and there was LOTS of smoke coming out and this guy took a quick look at it and said it, its definitely burnt oil smell, and could be transmission oil, coming out the dipstick and landing on the exhaust manifold. This car is completely stock, for now, im just wondering if this has happened to anyone before.? and how may i fix this? im kinda new at the car thing, but i know enough to fix a minor or mid range problem, theres no warning lights or anything and the emergency brake is down so PLEASE HELP ME. This is my first post on any forum so please bear with me. Thank you.!
