    Oil on the intake tube !!!

    LAST WEEKEND MY INTAKE TUBE KEPT COMING OFF. I USED A "T" CLAMP AND IT STILL CAME OFF.
    WHEN I TOOK THE AIR TUBE OFF IT WAS VERY OILY.........
    SINCE I HAVE THE CRANKCASE VENT TO THE ATMOSHERE, THE ONLY WAY TO GET OIL IN THERE IS THROUGH THE SUPERCHARGER THRUST PLATE.
    I REMOVED THE S.C. AND REMOVED THE HOUSING, THERE IS SOME OIL RESIDUE IN THERE, IT IS LIKE A LIGHT COATING IN THE HOUSING.....
    THERE IS NO FORWARD OR BACK MOVEMENT ON THE SHAFT.

    IS THIS WHAT I NEED TO REPAIR THE PROBLEM?

    R&D FZR/SHO Supercharger Rebuild Kit for C3/C5 assembly




    IF IT NEEDS A REBUILD KIT I MIGHT AS WELL ADD THIS TO MY LIST TOO......

    Are you using the stock oil breather box or a catch can?

    I am using the stock oil breather box with a catchcan......
    and my oil level is in the middle of the hash marks on the dipstick.
    i had a dry catchcan all weekend, also the catchcan does have a filter on the top so it can let the crankcase vapors escape.

    With the C5 & offshore racing you do, it might still be venting some oil vapor into the hull. I had that problem when I was using a can in place of the breather box. I had a light oily film on the whole intake tract. You might want to rinse your IC with some soapy water too, just to make sure it's not losing efficiency from being coated with oil.

    Probably not a bad idea to replace thrust washer. It does require some machining to your housing. R&D offers the service or they will send you specs to bring to a local machinest.

    the hose going into the ic was dry.

    the oil vapor breathes to the open air on my setup.

    in the parts description it does not say anything about machine work being needed for the s.c. rebuild kit !!!

    I have an engine 101 question. Where does the oil catch can go? I blocked off my beather hole on the intake and stuck a breather on the tube.

    anywhere you can find/make a mount for it.
    i would suggest having it so the escaping vapors do not get stuck in the hull.

    Yep, I think Glenn quoted me $150 for the machining.

    That's good that the IC hose was not oily. If it's not enough to make a mess off the entire tract, I probably wouldn't worry about it. I remember Rossnemo came up with an evac system to pull vapors from the case but don't remember how it turned out.
