1993 F250 I6 4.9L 170000 KMS This truck has had a hard life. It was always pulling heavy loads and constantly idling. Recently it developed an insatiable appetite for oil to the tune of 1/2 quart in 2 days. Its driven about 200~ KM in that time. There are no obvious leaks. Gaskets were changed a year ago and nothing drips to the ground.
I must confess I'm not too familiar with the inline 6 engines. Do these things have a PCV system? I know there is a breather hose that goes from the valve cover to the air box. The air filter with less than 20,000 KM looks awful. Something is very wrong here.
Old filter with the darker oily residue which lines up with breather hose.
Old and new side by side.
Holding up the old filter against a lamp.
