I know that blue smoke is because of burning oil or a blown head gasket. I'm live 60 miles away from where my car is because I'm at college so it hasnt been started for about 2 and a half weeks. I only got to run my car today for about 5 minutes because of time constraints, but when I would rev it up (only to like 2300rpm) the exhaust was pretty blue and scared me a bit. Is this because it just hasnt been runned in a bit or do I have problems???
