    Hi,
    I have a 6cta 8.3 450 diamond with 1700 hours on a 35′ BHM downeast hull. I am getting an oil leak from the connection from the turbo to the pipe to the aftercooler. Tightened clamp, but still slight leak 2200 rpm or greater. Oil level is ok. Any suggestions?
    Roger

    Roger, where exactly is the oil leaking from? Are you getting oil into your aftercooler?

    Pictures always help with stuff like this so we can all “see” whats going on…
