    It looks like it's the seals. I would get the service bulletin for doing them unless you want to get the service manual. All the best

    seals are bad. When you put new seals make sure to have TOP writing(its on seal) up...

    I took it to a shop. They ended up doing an injector too. Think it cost around $3,500. Had the truck around 3 years and had to get those seals fixed twice.

    So it didnt give you any issues While you drove like that? I gotta used truck and the 2nd day the seals were leaking. I was wondering if I could drive about 3 weeks before I put in a shop

    Oh ya you can drive it that way for a while. I never really did have trouble with how it ran with the leak. Mine was that way for several months.
