Obviously, the first question is whether this procedure can be done in my car and if so, I would need advice to do it correctly.
I don't understand very well when it says the following:
“NOTE: You must have the 2001+ style coolant vent tube as well for the LS6 valley cover to fit! All 2001+ LS1's will have this, and any LS1's that have upgraded to the "LS6 manifold" and pipes will also have the new coolant vent tube.”
I don't know if it's related to the above, but I have the doubt if my engine looks or like the pictures published in the note or like the one attached at the end of the thread, and if so, should I do some extra step?
I received my C5 a couple of months ago with 24k miles and it´s running really well except for this problem that the PCV valve sucks oil, sending it to the admission. I found enough oil in the throttle body and in the PCV valve to want to make the modification.
Didn´t drive a lot of miles yet but probably the engine used ¼ liter in 500 miles. I read this is “normal” but I really don't feel comfortable with my car using that amount of oil.
On the other hand, I am pretty sure that I have no piston rings problems. No smoke from the exhaust and original spark plugs look really good for the miles (picture attached also). No leaks either.
At the moment I´m using an oil catch can but as said, I would like to upgrade to the LS6 PCV.
Living outside the US, I must bring (15-20 days) the necessary parts from there and I would not want to disassemble and find that in addition to the mentioned parts in the article, I will need something else.......
The car is 100% stock.
From already, thank you very much for any advice!!

I need to do this to my car, and I have a 2001. Because you have a 99, I think you have a notch in the block that will need to be shaved in order for you to use the LS6 valley cover. I viewed your link, which is good, but I've also seen another link that illustrates with a little more detail where and how you can shave the notch on the block for it to fit. If I find it I'll post it. It's a great idea to do this as my car suffers from excessive pooling of oil. I run 2 catch cans and if I do a couple of track days they end up almost full. I'm hoping this will help reduce oil waste.

And I still haven't been to the track .....
If you could find the link and post it, I will be very grateful
In fact, my biggest question is whether when I disassemble, I find myself with something different from what the pictures indicate in the link. The one I attached looks different, there are some small pipes that I suppose are from coolant and I and I don't know if these are easy to disassemble and put back or if I need new ones.

Here is a better visual of how it looks below the cover and what you need to modify.
After searching and reading several threads, I will rephrase my question.
If I install a LS6 valey cover keeping the original intake on my 99, can I also keep the old style coolant crossover or should I update this to the LS6 style too?
You should be able to keep your 4 way coolant crossover that way. The reason the LS6 and later LS1s went to the new style coolant crossover was the flat bottom of the LS6 intake doesn't allow the 4-way crossover to fit.

the 4 corner crossover will not fit in it's original form, one of the tubes will make contact with the fitting on the ls6 valley cover... you can gently bend it and form it to clear that fitting but it is a pain in the @ss to do and get the coolant fittings to line up properly without being in a bind

Possibly I wil take the risk and bend the crossover so I can use the ls6 valley cover because I don't know how and what part I should buy to change the original lines.
Thanks for the advice!
Reformulated query. Need advice in a PCV coversion
