Nice!

 

I did this mod last fall before I installed the maggie. Cleans up some of the PCV hoses running around your engine too. I found a plastic plug to fit in place of the PCV. Gm makes one also and it is plastic but was like $6 at stealership.

 

I'm learning here so bare with me. What's the purpose of this LS6 valley cover swap? What is the gain/advantage/fix to the problem for the money spent?

 

Reduced introduction of oil vapor from crankcase pressure into the intake manifold. As well as somewhat better relief of positive crankcase pressure for the bottom end. Any type of Forced Induction drastically increases the chance for piston ring blow-by thus increasing crankcase pressure.

I think I got that right!

Hope this answers your question.

 

Thanks for the explanation. I just wanted to make sure it's not something I should have on my N/A 5.7.

 

It doesnt hurt to have on any LS motor, without the LS6 Valley cover they are prone to pulling oil vapor back into the intake. However as mentioned being FI only compounds matters.

 

What else do you need to do when you swap to the LS6 valley cover???

 

Just some vaccum hose if you dont have any and some vaccum plugs, both available at local parts store.


Update- No oil at all since doing the swap. So far so good.

 

how exactly do you have your pcv lines ran?

 

You can still run an oil catch can with the LS6 setup too...just extra insurance. There's a company that makes a bracket so you can attach the catch can to the r/s head, it's real clean looking. (AMW may be the company that makes the bracket, they also make great catch cans but their priced out of this world. I have an AMW that I bought when they were "only" $90)
