GURU's come inside.......... I was reading up on the LS1 to LS6 PCV conversions, and in my reading/searching I found that some instructions have a note stating you NEED to use the LS6 steam tubes (aka coolant lines) in order for the LS6 valley cover to fit.
I wanted to swap my LS6 steam tube out to the LS1 "X" style lines to improve the cooling in cylinder #7 and posibly #8, and upgrade the to the LS6 PCV system while incorperating a catch can.
Does anyone know why when doing the LS1 to LS6 PCV conversion, why the LS6 valley cover will not allow the LS1 steam tube to fit? Or has anyone done the LS1 steam tube inbetween the LS6 valley cover and LS6 intake manifold?
Apparently all you have to do to make the LS1 "X" style steam tube to fit under the LS6 intake manifold is to grind down some of the stiffening ribs on the bottom side of the intake. I'm assuming that the newer LS6 valley cover also impedes the lines some how. But I don't know......

Oh, and by the way Cory could get you an extra 5+RWHP with his port work on that manifold....

But what about the LS6 valley cover? Will it get in the way of the LS1 coolant tube?
Just when you think you have all the answers, they change the question. 
Perry may have further info on this, as he had a little on us about the PVC and seemed to be schooled in this area.

There might be away to re-route the coolant lines though. Someone posted in another one of my threads about how he used two of the LS6 style coolant tubes in the front AND the back of the block. And he routed some tubing around the manifold to conect the two coolant tubes. It sounds odd to me, but it might just work. I asked him to post up some pics. As of tonight he just posted up a drawing he made with microsoft paint.
Hmm I just did this the install wasn't too bad but I used the LS6 coolant lines with the LS6 manifold at the same time. The top of the covers doesn't seem too different unless the coolant tube interfears with the tube that comes off the front of the new valley cover.....
If I sell my LS6 intake I'll let you know if it works or not....

I remember seeing a pic of the LS6 valley cover in the LS1howto.com website. The LS6 compared to the LS1 had little elevated circles all over it which looked like they might get into the way.
I'll try to find pics of each and post them later.

Verdad Gallardo I just don't remember really the top of it seemed to look just like the LS1 cover. If you get in a situation where you really need to let know, let me know and I'll take it off it only takes 20 minutes.
I don't think all blocks require the clearancing as much as it shows on ls1howto mine didn't seem to although it can be hard to compare to the pictures.

What do you think about that idea?
I didn't think it would. But I was hoping I could get it to fit. I have heard of people using the front style LS6 coolant tube on the back and connecting the two with some tubing.

So the LS2 and the LS7 both have their steam tubes (coolant tubes) capped in the back just like the LS6?

I guess I'll just go with the PCV upgrade only and leave the LS1 intake tube as is. I guess I could check to see if it'll fit when I swap the oil valley covers.
Just to see......
