Under heavy accelleration, my 05' LLY blows some black smoke until at normal RPM's for wheel speed. Is this normal? The truck has 5800 miles...

Blow a nice cloud right in the window as you roar by! jermstyle 07-20-2005, 09:24 AM Yep... The Duramax is very smoke-free compared to most diesels. A friend of mine has a Cummins that has blown black smoke from day one without always being at WOT even. | ||
