Hi guys I have an old Terex loader with the 671 Detroit and it’s been a great runner we had the pan off not long ago and everything looked wonderful in there there was no metal in there anywhere and things were just looking great anyhow recently this thing out of nowhere has gotten wild crazy crank case pressure and it’s blowing oil out the vent on the side of the block like crazy and I’m at a loss I’m not sure where it’s at does anybody have any ideas I’m leaning towards some thing with the blower maybe because it’s Massive volume of air
