If you do not over fill the crank case, you should not have any oil coming out the breather tube. The problem Cat had with their engines was that on the 3126-E and early C-7 engines originally instructions were that it took 24 quarts of oil. When the problem got real bad and oil was getting on some radiators a new revision was put out by Caterpillar that the engine required only 19 quarts of oil.
The problem was solved.
Mine come out of the factory with the slobber tube already extended all the way down to the top of the mud flap and I never had any oil coming out of the tube. But I did read and I wittnessed an AirStream coach that lots of oil sprayed all over the bottom of the engine. It was ugly and that is where I first saw the revision that that gentleman got directly from Caterpillar.
Not sure if they had the slobber tube problem with the Cat 3126-B which did have the deep oil pan and it took a lot more oil.
I also heard Cummins also had a slobber tube problem, but again not sure what their problem was.
