I decided to post this in Internal since oil is touching it. <img border="0" alt="[shoot]" title="" src="graemlins/gr_guns.gif" />

My old intake is completely oil coated, and as you can below see my heads are also coated. So much that it leaked past the intake seal.

I knew the old style pcv system was bad, but not that bad.

What should I use to clean up this mess and short of the LS6 valley cover what can I do to keep this from coming back?

Thanks,
Eric

you said short of the LS6 valley cover....however that is the best fix for oil consumption as even a catch can is just a bad-aid. If you hadnt done the LS6 I recommend doing so. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Do you see those plastic clips that attach the knock sensor wires to the old coolant tubes?

If you are installing an LS6 intake, you will be removing those tubes, but, also remove those clips from the wires. They are just large enough to interfear with your new manifold and may cause a vacumm leak due to poor gasket seal. It has happened to more than one person on this board.

Damn thats a lot of oil, makes me wonder what my intake looks like... I'm going through 1qt of oil in 1000 miles..

Yeah the LS6 valley has the revised PCV system on it where it pulls from the center of the valley and not the valve covers like the LS1 version. For $45 its worth while I think.

I was thinking of doing this mod myself... where can I get one?

I got mine from GM Parts Direct but I think you can also get it from www.sdpc2000.com do a search on it and you will find a good amount of info on the change.

Eric,

Did you have the problem with 3-4 degrees of timing being pulled between 3000-6000rpms at WOT?

Thanks

Nope, I've never had any issues with knock retard.

Anyone interested... just do a search in the external engine section... there's a good post listing part numbers there, I bought all the GM Stuff (just over 100 bux.. beats going to hardware stores trying to find the right parts and making them work)

All I bought was the LS6 Valley cover ($45) and you can re-use your old PCV valve. Just get some caps to put over the parts on the valve covers, some 3/8" ID hose and thats it.

As you'll find out, installing the LS6 valley cover on an LS1 block requires a little dental work. There's a boss on the block that interferes with the baffle on the new valley cover, and it must be (carefully!) removed with a Dremel tool or similar implement of destruction. Check out www.ls1howto.com for an outstanding, step by step guide covering this swap.

For cleaning it, I would suggest carb cleaner.

My site (ls1howto.com) actually doesnt have an LS6 valley cover swap YET, but I think it'll be one of the next things I do and document. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
