i have a 98 legacy gt 5 speed with 141k on it. the head haskets were done at 126 and there are no drivibility issues with the engine at all. If im driving normal when i pull into my garage and open the hood there is a slight smell of burnt oil. The other day i was beating on the car and when i got to my friends driveway and opened the hood the smell of burnt oil was present and there was a little white smoke coming from the back left of the engine. Anyone have any thoughts?
