I have oil leaking from injector drive shaft area. Is this a bad o-ring. Its not running out just dripping from shaft.
I would tend to agree. The seal is aound $10 from Cummins. Or go to DODGE DIESEL VACUUM PUMP REPAIRING /TRANSMISSIONS REPAIR . His kit is pricier, but is complete, and also has a nice little how-to DVD in addition to instructions. HTHI'm betting your looking at the vaccum pump.
