Truck going in the shop when home too.
This oil consumption issue has gotten progressively worse and last gallon added was at 1500 miles and down almost a gallon again at 1500 miles .
Runs great , no smoke , mpg 6.9 to 7.3 over 3000 mile periods .
Word from Cummins is crankcase breather filter plugged forcing oil down thru the valve guides .
So we will try that and see what happens .
I tend to believe it cause it's pushing some oil out around the filler cap too.

 

Not at 555k lol...I've been documenting it tho .

 

No worries tony ,...it doesent level off .
Started at 7k on a gallon and down to 1500 now .
Cummins has updated the breather filters to a lifetime version and mine is probably plugged ...my non lifetime filter has 95k on it .

 

Well I hit Omaha today earlier than planned and the shop pulled me right in and I watched my buddy Jeremiah pull the crankcase filter housing off as about half a quart of oil poured out of it he said yeah this sob is completely plugged ...think we found the problem .
The updated version is just a flat plate with a pressure relief valve in it .
Cummins apparently knew they had a problem .

 

Wel see where the oil consumption goes now tho everyone is confident problem was there .
When I hit the shop today it had used 2 gallons in 2100 miles .
Shop is confident on the crankcase filter as the oil consumption has increased so fast along with filter housing full of oil .
Leave Saturday for LA and we shall see .
