Re: High Mileage Cummins??

Blow by could be high, it just depends on the engine. When you start it, remove the oil fill cap and see how much "smoke" comes out of the fill tube. 12v's also have a breather with a road draft tube. It is nornal for these to be wet and to have a little haze coming out at high mileage. If it's dripping oil out of their continuously, or smoking worse than the exhaust, it has an issue.
