    I understand the details as far as adding grade to your line so that it will still drain in a downward motion but that wasn't explained for the guys with not as much mechanical knowledge.

    Good mod.

    Totally understood. In all honesty, if I had seen your post I would have done it that way. Less chance of clogging the filter from the inside.

    In fact, I'll probably modify it this week to run the drain straight down. I'll post another pic when it's done.

    Thanks for the heads-up.

    great Write up. I agree that the filter should be up from the drain but you could leave it in the same location just rotate it up so the oil flows under the filter.

    I'm wondering now if there's a way to put a couple of schrader-valves on this setup.

    One near the filter, to only allow fresh air in

    The other near the drain, to only allow oil/dirty air out.

    It would basically make a one-way downdraft airflow circuit. Would eliminate the need to drain the valve, still allow the system to breathe, and not allow debris back in.

    Maybe I'll pick up a couple of schrader valves today and see if I can fit them inside the tube.

    Any thoughts?

    That is an interesting thought. I'd like to see if that can be done.

    Used a single 3/8 nylon T and 3' of gas hose from Napa Auto. Used one of the "old" pieces of tubing to plug the cover holes-similar (a U) to what is shown in the pic. Nothing on the end..just terminated it at the muffler outlet. Havent seen anything drip from it yet and if it does, the exhaust pulse will simply blow it outwards away from any possible contact with the tire. Easy job-took maybe 1/2 hr and it does seem to idle smoother.

    Wulf,

    Read the entire post before commenting. Great idea though.
