I bought stock 02 heads for cheap b/c my 98 had a miss shift and bent valves so this was a cheaper route. I already have the valve covers coming but what I dont know is is the ls6 pcv upgrade necessary? I mean i know ill have it all apart already and could change the valley cover and complete to this system easily just wondering if i really need to or not?

nope you can keep your ls1 style. i had some oil consumption issues so im upgrading to the ls6 pcv.

How bad was the consumption and how did u u notice the issue? Ive been trying to read the best i can about this system what are people using for a catch can and the details of how this works are simple im sure but could u school a newb like me?

well you can tell if youre using oil just by checking it (duh) i was using about a 1/2 quart every oil change and it was all over my TB and on the inside of the intake. Im in the process of reuilding my motor now and I was originally planning to just run a catch can, but when the stock pcv lines broke I said **** it and bought the LS6. The LS6 draws from the valley with an oil/air serperator, some people have good results of using less or no oil, otheres dont. So im gonna try it anyhow, besides, I get to get rid of all those ugly black hoses.

LOL yea i knew checking it but I was more curious of if you were seeing more oil in your intake or what. Also if i get an ls6 intake does this change the pcv conversion any?

nope, I run an ls6 intake. I had more oil in my intake, it was almost like puddles of oil.

Great thanks for the help pretty much answered all my questions the conversion looked pretty straight forward to me and i agree on the ugly black hoses everywhere.

I had the same problem my self on my 01 and i did away with it all , i cap everything off and put a breather were the oil cap was and put a 5.3 pcv valve with a small piece of hose on the end of it. And i it solved my oil problems . My oil level hasn't moved on my dipstick for a month and i am a daily driver. It only cost me $4.99 for the breather cap, and $3.99 for the block off caps. If you need pictures ,i can send them to ya!!!!! just pm me

I would skip the LS6 valley, I did this mod years ago and got just as much oil in the intake as before. I run a catch can now, problem solved.

Or you could do it the way i did, and save money both ways and don't have that excess under the hood, and only cost 10.00 at the most.

you might have to modify your engine block a little for the valley cover. i know on some of the blocks you have to grind a spot down a little bit because the cover wont sit down all the way. i think it's the some 00 blocks and older. i have the ls6 pcv on mine but i didn't have to grind at all cuz i have an ls6 block. i'd try the 8 dollar pcv valve from gm first before you try the valley cover. it might work

Ya I had to cut the casting boss off my 01 block to fit the valley cover. Definately wasn't worth it. I say skip it.
