    2019 Cummins 6.7L - Oil Leak

    I have a 2019 Cummins 46K miles.

    I noticed a fairly substantial oil leak on the front of the engine.

    I was thinking of the seal on the crankshaft?

    Has any else this before?

    I noticed a 3 inch puddle from this area once.

    One day and never again.

    We all need one of those self healing oil seals! LOL.

    My advice would be to clean up the area with brake clean then keep a close eye on it to see where it’s coming from.

    A little oil can go a long way with the fan going.
