Hi all I have an 84 Dodge D-50 with a 4D55t that I rebuilt I have about 15,000 on it since rebuilt and I have had a oil blow by situation from the beginning I keep getting oil out of the breather on the valve cover is this normal for these engines? I’m new to these Mitsubishi diesels it’s usually not a lot in about 3,000 miles which is my service interval I have to add one quart usually is there fix for this?
