    Catch can...

    How hard is it to hook up a universal catch can to an ls1? Does any company make a direct bolt on for our cars?

    Cutlass: I take it that one end plugs into your existing factory PCV line and the other to your throttle body. Do you have a pic showing the connections at the side of the throttle body and PCV?


    Anyone interested in asking about a GP on these?

    am I seeing that right? Looks like your pcv line is still going into the TB?

    That's why I asked for another pic or explanation of how it is set up.

    In retrospect of the can the hose that connects to the top port comes from the LS6 Valley cover tray. The hose that connects to the side port connects to the Intake. the hose connecting to the TB does not change

    The catch can has an IN and OUT connection. The intake manifold vacuum creates suction through the catch can and into the LS6 valley cover which sucks on the crankcase from less oily place then the valve cover. The result is less oil consumption through the PCV system. The catch can will catch any oil that does get sucked in the PCV system (if its a decent catch can, don't go ultra cheap on a catch can. It needs to have some sort of oil separator material in it.)
    The other PCV line from the valve cover to the TB is the "clean" air make up back into the crankcase. Others choose to use a breather filter for the clean air makeup.

    And what if I don't have the ls6 valley cover, just the intake?

    You can hook a catch can up into the stock PCV system

    Same here. Makes a whole lot more sense to me now.

    I like how the bottom just screws off. After 6000 miles, this is how much oil I saved from burning through my intake. I'd say about 1/4 to 1/3 cup

    I will see if any of our sponsors are interested in a group purchase. Look for a thread in a couple of days after I have a chance to research what is currently available.
