    That looks identical to the pair I bought from Kentucky Speed. They are doing a nice job on both cars. Catching about 1/2 of an aerosol lid full of oil on every oil change. Easy to drain, no issues here.

    Ive seen a polished one in person before. A guy got one for his turbo kit he got off ebay. They arnt that big. Im not sure where yet though. Gotta get it here and mock it up and see where it will look good and mount correctly while doing its intended job. But im sure i can find a good place. I still have an EGR/AIR setup on my car so setting it up off the passenger side head is probably out.

    Usually they are for the PCV system and keeps engine oil from making it's way to the intake manifold..

    The term "blow by" is originally referring to a case of worn rings that allow cylinder pressure past the rings and into the crank case, and the excessive pressure pushes oil up through your pcv breather system. This is not what a catch can is designed to cure. The motor is in need of a rebuild.

    In the case of the LS1's, it's a simple matter of a poorly designed pcv system that actually sucks the oil into the intake track. Has nothing to do with worn rings. In which case a catch can is a worthy addition.

    Yep, it helps to keep oil out of the intake track which ultimately means, out of the combustion chambers.
    Oil in the combustion chambers delutes the fuel charge, causes detonation, coates the intake valves as well as the intake runners and the inside of the intake itself. It kills HP in extreme instances.

    There,,,,have I scared you into buying one yet??

    yea that is weird...autozone has them if you want the cheap fix compared to factory ones, just match up the letters on both plugs b/c the one you get from autozone has all same color wires

    I've read it does help reduce it, but that was on a different car forum.

    But you learn something new everyday.

    No biggy. With all the kids nowadays and these new phrases they are using, I don't know what people on here are saying half the time anyway

    You say, "I have a woody" and I think you are talking about a car.
