Hello guys, new to the group. Just bought an 04 GMC 2500HD Duramax; now have 1500mi on it. Yesterday while stopped at a light, I noticed blue smoke coming from the exhaust. After a few moments it stopped and I haven't seen it again. Since this is my first diesel, I'm not sure if that was normal or not?
