There seems to be a mixed bag of people who have done the LS1 to LS6 PCV conversion... With an even bigger mix of results.

My '01 camaro would burn through about a quart of oil between changes (not a big deal as long as I kept up with it).

This year, after coming out of storage, I noticed on the handful of times I did run it that it noticeably smelled of burning oil.

So I'm thinking with a new cam, there's going to be even less vacuum to the PCV valve which may lead to even more oil suction?

Would converting to the LS6 Valley cover have any merits? Or is it a waste of money?

 

I changed mine over and it works wonders.. I dont have to add a quart between oil changes anymore and it also cleans up the engine alot.

 

I loved doing the conversion, because you get rid of a bunch of hoses and potential leak points. I feel it lets less oil through than the LS1 PCV. The best solution is both the LS6 valley cover AND the catch can

 

Does the LS6 valley cover have a PCV valve already? If so, why do people also use the LS1 valve.

 

yes, the 04 ls6 valley has the pcv built in

 

So pull the old valley: trim a piece of the block off for clearance, put ls6 valley in, replace PCV hose, and plug the valve cover? That's all?

And no change in performance?

 

yes thats pretty much it..

you will also need the LS6 coolant crossover line and the two plugs to block off the rear ports on the heads

 

Would a 2001 already have the ls6 coolant crossovers?

 

no they came on LS cars after 02 ( CTSV, GTO, Corvette)

 

I may be wrong: but I was under the impression that all cars 2001+ came with an LS6 intake... Which I'm assuming means they came with LS6 steam tubes.


I think the ls1 steam tubes connect from front to rear. All mine has is a single front crossover.

 

Honestly not sure on the steam tubes. Mine has the 4-corners tubes. I have some pics of the LS6 valley going in - didn't get one of the thing I ground off in the block. When you grind it off, you'll be like - why was this even there? You'll see what I mean.



5. PCV vomited oil into intake. LS6 PCV and valley cover just arrived



8. LS6 valley cover installed



9. Freshly ported heads installed. In retrospect, I wish I had installed the 918 valve springs while I had the heads off. Saved them until I did the cam 6-months later.



10. I kept the LS1 crossover pipe. THis was the hardest part. Major interference from the PCV vacuum port.



10. Crossover pipe routing figured out.

 

Thanks for the photos. Here's a pic of my motor right now. I'm guessing those are LS6 steam tubes on there.

I'm thinking about the LS6 valley cover and catch can also.

 

Yes, that's the LS6 tubes. I wasn't sure if they also come on the 01-02 f-body, but I guess they have to. GM ran the different tubes due to less space under the intake manifold. Personally, I like the LS1 style for preventing trapped air, so I did what I could to keep it.

 

Mine has the LS6 tube as well and also came with the block pre tapped for the LS6 chain dampener.

 

Every 01-up motor has the ls6 tubes to clear the ls6 intake so if you have an 01-02 car then you do

 

That's another thing I've been looking into... Whether or not I should get the damper. It's not a race car by any means...

 

I have read of stock LS2 chains with a LS6 dampener out last high dollar dual setups with no dampener. Read this a few times on the Vette forums. So I figured it was well worth it for the little extra cost. My car is a garage queen that only gets driven 1500mi a year, so no race car here but I do like to rip on it once in a while.

I also think a good SFI balancer is a great investment as well. Get a stock size powerbond or ati with a chain dampener and you will be dialed.

 

Before going with a LS6 valley cover try going with a fixed orifice style pcv valve first, that's what the 2004 on up LS6 valley cover has, along with everything gm 2004 on up has (fixed orifice valve).

 

If I'm in there for a heads/cam swap wouldn't it make sense to just do it now?
