New guy here from Arkansas.  Grew up on the farm and been around heavy equipment and diesel engines my whole life.  I bought a 2004 Dodge Ram 2500 about a year ago.  It has the 2004.5 5.9 Cummins.  I started noticing recently that I was getting quite a bit of white smoke from the blow by/breather tube under the truck. I bought the truck with around 130,000 miles on it and it currently has around 180,000 miles on it.  I changed the crank case vent filter on it thinking that might help.  While I expect the motor to have some wear and show some blow by for it being this old and for me hauling with it on a regular basis I am a little surprised at the amount of smoke. I did the oil cap test, and while it bounces around more than usual it doesn't just blow the cap off.  I have had equipment that we have rebuilt, and it not have this much smoke coming out of the blow by tube. I have done a lot of reading, and was just wondering if anyone else has seen this before. The smoke is really only noticeable while sitting still, and I don't smell an excessive amount of burnt oil while driving, can only really smell oil while outside the truck with it idling and it still isn't that strong. Truck is not using any oil and it isn't making any oil (such as fuel or water getting in the oil) and not smoke out of the exhaust.  Still have plenty of power and my fuel mileage hasn't changed any either. I would like to try different options before going to the extreme of overhauling it. Any suggestions???

Have you tested the injectors? Good bet they are starting to hang open and wash the cylinders down too.
