OK, I know what the upside is to the delete... but are there any downfalls?

I recently took my intake of my LS2 with 5K miles on it and there was oil all over the intake ports on the heads... I was disappoint b/c I have had a catchcan since the begining.



So since I am putting brand new heads on... I figured now may be a good time for an entire delete.


Now I need to know exactly what I need to do...


Refer to the picture for the following:

In red there is a hose coming off my passenger valvecover and dumping into my intake tube.

**my solution:

A. cap the intake tube and cap the valve cover. user a breather on the oil cap fill hole.

B. cap the intake tube and put a breather on the end of the hose coming from the valve cover.


In green the hose is coming from the valley cover going through a catch can and dumping into my IM.

I dont know what I can do to delete this.


In blue I am not sure what this does.


PLEASE HELP ME FIGURE THIS OUT!

 

bump.

 

you prolly would get more replys in the LS2-LS7 section.

 

if you dont know what it does or why its there, do you think its wise to just arbitrarily remove it?

 

and that's why I posted here before doing anything

 

A or B works, that hose has to have a breather on it or another one in the system.

The green hoses to your existing can... cap the intake manifold end. Next, take the hose from the valley cover and send it to a catch can with a breather (something like the plastic 1 Qt ones summit and Jegs have) Get one with a drain, it will make it easy to dump. You will be shocked at how much crud makes it out.

On the other lines, leave them alone, not sure what they run in your application.

In my car, I ran both the valley cover, and the valve cover hose to the same catch can w/breather. I originally had the valve cover one capped, and the excess crancase pressure popped the front crank seal out!
