Just stopped by 7-11 and guy had his D;)uramax running. I notice blue smoke. I asked him how many miles on it. Almost 200k. First Gen with 5 speed. Good looking truck.Said leaking and using oil.I had my 92 Cummins with over 300k. No use of oil or leaking.But body full of rust from all the Blizzards.lol

Well that proves it...Duramax'es are no good.I'm going out right now and get rid of mine.....:)

Few week ago in town I saw a pick-up truck (diesel, but don't know what brand it was). The owner modified the exhaust so it came out the bed of the truck with 2 pipes that were higher than the cab. Really a show off. It was belching black smoke like an old freight train. I've been told if you mix oil with the diesel it will make the smoke black. I was really irritated by the smoke. I do remember the day when diesels did belch black, especially the semi's. I think anyone who does this is a pure idiot. But leaking oil is another matter. That's not a deliberate attempt to show how much of an idiot one is.Hope the guy you referenced to above can get it fixed.

So, if Chevy switches from D/max to Cummins, they will have a rust free 300,000+ mile truck?Isn't that what we all want :@Was the Duramax a local truck or an out of state visitor?

Sounds like more of a lack of maintenance than an inherent defect. Any motor that is not maintained is going to wear, and one indication of wear is blue smoke from the exhaust.

When i'd be pull hard through the mountains or jumping on it trying to get up to speed after a turn about, my old f-350 would put out quite a bit of smoke. I had a towing tune of 60 hp(higher boost, better fuel mixture, adjusted shift points). But then there are the goofballs that put those crazy tunes on their trucks just so they can coal roll through traffic thinking their "cool".. That **** needs to stop
