    Whats the purpose of oil catch can??

    Not sure what the purpose of puttin one on there is.
    Is this the 3/4 inch hose that connects to the intake right at the throttle body?

    I plan on puttin on a cai kit. Is this when i gotta do that mod?

    The factory crankase vent hose which is 3/4 goes into the stock air plumbing, and some aftermarket intake kits have a provision for the hose hook-up via nipple. The purpose of adding a catch can, is so the oil/gas vapors get captured/contained inside a can that can be drained easily in most applications so you keep the entire intake tract free from oily residue that will eventually lead up to gummed up air tubing and intercooler inerts!... There are several types of oil seperators/catch cans, 1 is vented to the atmosphere and the other type is closed loop where as the oil/gas vapors are contained in the can for draining, but is still hooked up to the intake tract to evacuate the crankase pressure...PR...

    DEEGee, nothing for you to worry about. There is nothing to "gum up" in a NA ski and the catch can seem necessary on some SC intercooled skis but not all.
    I don't run one and there is not one drop of oil in the intake. Some ski need it, other don't, wish I knew why.

    Ah yup, didn`t know you had the NA model, so Slpash is correct, you really don`t need it.The ski`s that are run hard at high RPM`s benefit from the catch can...PR...

    Pale Rider, thanks, maybe thats why i have no oil in the intake, I'm not modified much. Just a Vortec SC impeller and Riva intake. I only turn 8000-8100 so thats why no oil.

    Thanks!

    There is prolly also a mechanical reason why some machines spit out more fuel/oil, And it could also be contributed to aggressive riding, more full throttle runs, maybe!?...PR...
