We just picked up '05 Mack granite with the AMI-370 Mack motor, today when I was backing it up my driveway a splash of oil came out of the crank case breather tube. It did it 2 trips, it's not much oil just enough to leave a little streak in the driveway, and then drip a bit after it's parked. The oil level it perfect and there is nothing foreign in it. My buddy is a diesel mechanic and says it's OK.Why is this happening? My driveway is kind of steep, is that what causes it? Thanks, I will post pics soon!
