    LS6 valley plate

    My catch can is catching a TON of oil. I've heard of upgrading to the LS6 valley plate which is said to eliminate PCV oil consumption all together. Is anyone using or has anyone ever used the LS6 valley plate? If so, is it worth the swap?

    doubt that will work, cause you'll still have the same blow by and crankcase pressure as with the ls1 valley.
    '00 Silverado, '98 Trans Am, and a couple other toys.

    I understand the blow-by part, but I'm trying to reduce the amount of oil that gets pulled through the PCV. I have to add a quart of oil about every month and a half.

    do you have your oil cap vented? that may help a little with pressure.
    blown transmissions are about as useful as 97% of the guys on this forum

    i run the ls6 valley cover and my two valve covers vented. all tie into a -10 line that goes to my breather/catch can. My can had next to no oil in it with this setup.

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    That's the answer I was hoping for, thanks Quik.....and where can I get an LS6 valley cover?
