I work in a main fleet garage and i have a 2009 cv713 granite sent to me by county service garage for "making oil". Was brought in for same problem month and a half ago found torn o ring on #3 EUP, put new o rings on all unit pumps and replaced lift pump test drove truck 3 days no problems return to county garage. 4 weeks later truck is 3 gallons overfull on oil again. unfortunately i am the last to get info on the truck like " when did it start again?" because our drivers pre trip every morning and "it just showed up overnight" or "it wasnt like that when i checked it this morning" any ideas on where it is coming from? definitely diesel because of the smell.
