    My friends 2011 Pete blows air OUT of the air cleaner every once in a while-this some sort of self-cleaning function?

    Just the standard quick blow off? every ten, twenty or forty minutes: normal.
    Happening every minute? Leaky sense line to the governor or unloader.
    Oh wait a sec. you mean it's coming out of the air filter housing?

    The engine has a hard time running if the intake airflow is interrupted to force outward.

    Sure its not just the waste gate dumping to prevent overboost?

    Where is it coming out? The air dryer will discharge a little bit of air when the governor kicks in and shuts off the compressor, this is how it blows out the water.

    Well,I haven't seen it myself,he says every few hundred miles or so the canister blows dust OUT,as if its cleaning itself-it doesn't affect the engine any when it happens.We haul rock out of quarries,so it's pretty dusty conditions

    Could you elaborate a little,magoo? would that cause a back surge out of the air cleaner?
