OK, I'm looking for some advice here. My VW recently started having trouble starting, but when it does start, I get a thick white smoke from the exhaust that smells like gasoline. There is also a liquid dripping from the exhaust that has an oily consistency. I checked the oil and it's clean, but I have noticed the coolant has gone down a bit. It's my second engine in this car, and I have 165k on it. Any ideas on what's going on ? Is it time to call the junk man ?
