i'm planning on getting a 2004 LS6 Valley Cover (PN 12577927) for my 2001 LS1.

being that the RevXtreme catch can has a built in PCV, would this cause issues with the 2004 valley cover (which has the fixed orifice instead of the PCV)? and should i go with a Saikou Michi instead?

my concern is that it would be like running 2 PCVs and maybe it would cause some weird vacuum issue

You could run 5 PCV valves in line, and no issue as the valve only allows x-amount of vacuum in. The restriction is the fixed orffice, and it has no one-way check valve feature so gasses can flow both ways.

Agree^^^ No issue with the RevX PCV valve.

Didnt know if you know. On the 01 block you have to notch out a section of the block for the new valley cover so it doesnt hit.

ok, after much internal debate, i decided to order the 01-03 LS6 valley cover, and the RevXtreme can. i couldn't find any comparisons of the oil separators between the early/late ls6 designs... only that the late design has the fixed orifice pcv built in.

with the 04 cover, i'd be stuck with the fixed orifice, which i read can potentially cause vacuum issues if i do a H/C setup down the road. with the 01-03, i can use the PCV in the can, which will keep the clean appearance, and i can always add the external fixed orifice later if i feel so inclined.

just did my 1st oil change after the LS6 valley cover & catch can install.

although only 500 miles passed since the swap, the catch can was completely empty. not even a single drop came out. While doing the swap, there was a significant amount of oil pooled behind the PCV valve on the stock hose, so i was expecting at least SOMETHING in the can.

Looks like the LS6 Valley cover really works. can't wait to see if oil consumption really improves this year.

Which part number did you end up using for the Ls6 valley?

the pre-04 valley cover is 12568002. you also need the plug for the drivers side valve cover: 12568011
