So i've seen the diagrams that one of the members drew up for all the possible combinations but I still don't trust myself with not messing it up.

I have an ls6 intake with a stock ported throttle body. And im assuming the stock ls1 valley cover? Where exactly am i going to run my hoses? :x

Its a billet catch can pictures of connections would be prime, thanks

anybody? the install tells me to run a hose from the top of can to the passenger side valley cover. and another from the side to the pcv valve.

but the diagrams online: https://ls1tech.com/forums/11059703-post70.html

are showing the 2 lines going to the pcv and to the intake, nothing to the valley cover

im confused.

Vroom!

If you have a LS1 valley cover, then use the first picture in that post and run the lines accordingly.

Only LS6 valley covers have a line going to them because of the built in PCV valve.

How do i know if I have the ls1 valley cover, its a 2000 and I just put an ls6 intake on.
Also in those 2 diagrams, does the ls1 valley cover determine if the pcv is external or coming out of the intake?

I really don't wanna route these lines wrong

Vroom!

If you haven't installed the new valley cover, then you have the stock ls1 valley cover.

Yes, the valley cover determines if you run a external pcv valve or not.

I used 405HP Z06's diagram when I installed my dual catch can. Seems to be working great for me and is definitely catching oil.

Okay, so with my stock ls1 valley cover, I have an external PCV valve, so according to his diagrams for a single can. The 2 red lines are what I connect and thats it?

PS. how did you block off the port on the back of the passenger side valve cover?

Vroom!

I'd run the green line also. I used a rubber vacuum cap to block the port on the passenger side valve cover.

is that also 3/8 ID tubing?

also did you run hoses all the way from the drivers side through the pcv like he has shown? or is that line already there as well?

Vroom!

Yes it is

Could you point out exactly where the connections need to go? I grabbed some pics

Vroom!

the hose near the throttle cable going into the port on the throttle body is the green line and underneath where the original pcv valve connects to is the red line.

Vroom!

I ran a new hose from the drivers side rear port to the catch can and then to the intake port. All the old pcv stuff on my car is gone but i did reuse the factory pcv valve holder.

so from the drivers side rear port does it just skip all the pcv stuff, instead of running a hose form the pcv to the catchcan

Vroom!

The hose coming off the driver side port has the pcv valve in it and that goes to the catch can

alright, so yo usaid you ran a new hose all the way from the rear port, did you just push the pcv valve into the new hose? Im assuming its got male connections that push right in? I haven't taken anything apart yet to look

Vroom!

I just reused the stock holder for the valve and used whatever i had in the toolbox to hook it up to the hose

thanks for all of your help vroom, I'll be hooking this up tomorrow!

I did a Home depot Husky mod, I put my pcv valve after the catch can thinkin that would make it (the valve) last longer. Actually the thing that prompted this mod was oil dripping out of that stupid strap thing on the pcv.none since doin it my way...is there any reason to put the pcv valve before the catch can on a ls1 system (dirty loop) as shown in the diagram?
