    Default Fuel in oil

    Ok to start bought the truck after 6 years of sitting. What I know from previous owner..white smoke at idle..she had both heads replaced due to a cracked head. Injectors and return lines were also replaced at this time. I cleaned fuel system with diesel purge and replaced fuel filter. I replaced pmd due to self acceleration..almost crashed lol..has lots of white smoke at idle. Checked coolant levels and all good there...check oil levels and it will build 4qts in less then 100mi..smells horribly of diesel...paper towel test shows definitely has diesel...no external fuel leaks...no codes...can injectors cause this much fuel in oil?...what other cause could there be for this much diesel in the oil? Thanks in advance for any help provided. Also when it does warm up it will not crank or start untill it cools back down under 160.

    Hi
    Welcome to TDP

    Injection pump is likely toast

    Fuel leaking out the front of the pump and into the crankcase.
