    I thought my rear main seal on my M1008 was causing my leak but I've now found I have oil leaks at the rear of both heads. I may purchase the UV dye to make sure, but my questions are:
    1. Does this sound like more than just a head gasket change?
    2. If I have the heads removed what else should I do while they are out? (60,000miles)
    3. Is the only advantage of 6.5 heads on a NA 6.2 better cooling? Or would it be worth it If I plan to add a turbo in the future to make a swap now?

    My truck runs fine otherwise, just want to get rid of the little puddles.
    Thanks in Advance.

    Are you sure the leak is not from the vacuum pump gasket located at the base of the vacuum pump?

    It's possible but the oil stain is from the head mating surface straight down, like it was masked off or something. I probrobly should get the dye.
