    My 2000 caterpillar was doing that tore it down and it was number six piston was bypassing oil horribly I was using about 4 gallons every 20,000 miles !
    If I idled excessively in the winter it would actually leave a puddle on the ground !!!

    Yeah that's not good. Take manifold off and find what cylinder its coming from. Then tear down. To find problem. Could be anything from bad head to a piston issue. Had n14 do that it was a bad valve guide.

    That turbo looks like an N14 turbo? I'm wrong more than likely.

    You don't need to take the manifold off, run it until warm and use a forward looking camera to see which cylinder is cold.
     
    Intothesunset Thanks this.

    The advice is it's not good. Oil shouldn't be there. You have an internal problem. Pull the manifold off to determine which cylinder is the problem. And start tearing down.

    Does it matter? The head is going to come off anyway.

    Well I didn't read that from the op, the op is looking at an engine so using an filr camera will tell you more than what the seller is claiming.
