Blue Smoke At Normal Operating Temperature
I've read of people having blue smoke at startup especially when cold, usually indicating an injector problem, but I'm having blue smoke at normal operating temperature. Could injectors cause this also? The oil level has been exactly the same between oil changes. I run power service at its recommended dose every other tank. The engine has not been worked hard for awhile. Maybe just need to go pull something heavy?

Thats what I would think too, black or white for injectors. Always thought blue means oil but some here seem to think injectors. Guess I'll have to hook up something heavy and drive this weekend.

I sure hope that isn't the case here. The motor runs strong as ever, sounds normal, doesn't get beat on much, and has never had any sort of programmer, chip, or pressure box installed. Also only has 44k on it. At least it would be covered under warranty.

I'm new to diesels and cummins. My transplant engine blows some blue smoke on startup if I've let the truck set for a couple of weeks. Once on the road and starting every day there is virtually none. Does use a small of oil between 4500mi changes. Truck seems to have plenty of power and getting flat 20mpg in dually body. Normal? Hope its not inappropriate to ask question here.
