Which would be the most effective?
the cover is about the same price but more work. However I dont mind the work just want the best bang for the run.

I dont know, i say if your going to fix it do it right. LS6 valley cover. Especially if you are taking your manifold off, replace the valley cover at the same time. If your looking for easier to install, they are both easy catch can takes less time because you dont need to remove your manifold.

LS6 valley cover is a better PCV system. The LS1 style is pulling fumes form a splash lubrication area, so it's gonna suck up oil at high RPM. In the cam valley, there is no splash lubrication so there is MUCH less chance of sucking up oil.

However, the LS6 valley does not eliminate the VC to TB hose. That is still taking fumes from the VC. I'd put a catch can in line with that (and I will soon) to help eliminate as much oil as possible from getting ingested.

This is from my swap. (We've got mice here. Mice won't chew thru steel wool)

Thanks thats what I needed to know. Ill start with the valley cover and later down the road ill only have the easy catch can install left.

Does the ls6 valley cover come on any other blocks than the ls6 such as the lq9 or anything else?

^ Comes on LS6 and up blocks. LS2,6,3,7 and 9 (9 might be a modified version for FI.) LS1 was the last design to use the "crappy" PCV system.

It's just an updated style of PCV system that is used now. Not specifically the "LS6 valley cover."

Im running a Rev Xtreme can & 04' ls6 cover.. I'm still getting oil in the intake, I'm fed up with the pcv system.. Ordered a Metco breather today & taking off the pcv, problem solved.

I have the LS6 valley and it was a total waste. Got just as much oil in the intake as before. I'm now running a catch can with the valley and it stays bone dry. I say skip the valley.

i have the Norris PVC Catch Can(installing in a month or so) anyone run just the can and no valley cover with any luck? and i hear that the ls6 valley cover is NOT a direct fit and yo have to notch out the block on 02 and under ls1's for the internal pcv valve to fit. is this ture?

so if your only going to be using a breather and removing the PCV, what could the issues be with this? i ask only because i bought a norris catch can and am thinking of geting the ls6 valley. i want the best affective way to prevent from smoking/ blowing out my exhaust at WOT and oil in my intake.

let us know how this turns out - that's a great price and i want in if they're selling the correct part at that price!

Some say it makes your oil dirty faster, doesn't get all the oil contaminants out & can sometimes mist oil past the breather filter.. Others say it's just fine as long as you stay on top of your oil changes & drain the oil while the motor is hot.. I'm actually going to add AN fittings to both valve covers & run them to a vented breather tank.

I spin both cars pretty close to 7000 well one i spin to 7000 and just normal driving I am definately throwing oil. I plan on eventually doing a catch can on the vette for sure. Looks like an easy install from this...

Also its the exact same part number I ordered.

The only thing I dont look forward to is possibly shaving the darn valley or cutting it. Since its an Lq9 IRON block im wonderring how much work I have cut out for me. Has anyone cut the IRON block for this to fit?

Definitely get the 04+ LS6 valley cover. I'm not sure how people don't see results with the mod. I certainly did. I used to add almost a whole quart between oil changes. Now I don't add a drop after the valley cover. I had my TB off last week, and the inside of my manifold looked pretty clean.

I've seen cars run both LS6 valleys and catch cans and they still suck a bunch of oil into the intake.

We did with my LS1 block. A few minutes with a sawzall, no big deal.
