[(92)cummins]

my trucks od doesn't work but it feels like my truck is burning a lot of fuel and i have noticed a considerable amount of blow by then usual, its a stock IC with bout 380xxx miles

If its the auto you can put OD on a switch to get it working while you trouble shoot why it wont kick in by itself. Mine is operated threw a floor mounted light dimmer switch.

It just comes with mileage and wear. Rings showing age and mileage probably letting more past them.
