I have an 05 LLY Crew Cab 4x4 dually and my mods should be in my signiture. Last weekend while hauling my airboat to the coast at 65MPH the truck started rolling white smoke and I am talking about 1/4 mile long two lanes wide! When I pulled over the engine was covered with oil from the crank case vent. I removed the oil filler cap and she was blowing white smoke in the air like a train. The tuner I was using was a hand help PPE Standard and I had it set at level 3. It looks like I burned a hole in a piston. I drove the truck home 210 miles and used 4 gallons of oil. I am going to pull the engine and rebuild it but i am done with the PPE tuner. I used HPtuner on my C6 corvette but I have never used it on my Duramax. The truck still runs, should I try and get a scan before I pull it apart?
Oh the airboat weighs 4600# but it has a great deal of air drag.
the truck has stock size tires and a 110 gallon fuel tank in the bed.
When I rebuild it I will be adding a lift pump, new oil pump, new water pump and injectors if needed. I will also replace the drivers side exhaust header with a non restrictive one, new after market down pipe and weld the EGR pipe shut on the back Y pipe.
Where is a good place to get a config file for my truck and a beginners lesson?
