I have a 2007 Mack granite quad axle dump truck with a MP7. Bought it from its original owner. Truck runs solid with 390k on it, no loss of power. Oil pressure holds around 40/idle 60-70/driving but major blow by & oil leak from the blow by tube(literally puddles under blowby tube after it warms up & leaves a steady drip trail while driving) & getting worse!! Going thru about 3 gallons a day between leak & oil burning!!! Ordered a inframe kit from PAI. Hopefully that solves my issue. Has anyone seen anything like this before?
