Default amw pcv routing?

I've searched and searched. I've seen different configurations. Once and for all, is this right? I came out of the valley, hit the top of the can, out the bottom, through the valve, then into the TB... is this right???

I used to have it that way. I recently switched to having the pcv valve BEFORE the can.

No noticeable difference. I just figured if it went thru the PCV first (as original) and THEN the catch can, the air going through to the intake will be as clean as possible. If you do it this way, you need it coming out of the valley cover (on the LS6) to the fat end of the PCV first, then skinny end into the catch can.

Easy to see if you follow this picture

I have it the way you do.. "Catch Can then PCV"... with the limited oil catching of the PCV.. It would seem more logical to have the Catch Can do its job 1st (IMO) and then have the PCV handle what little the Catch Can doesn't..

You can't drain the PCV but you can drain the Can...!? I think either way will work... (i guess the debate and the research is on ! LOL)

I'll confuse you even more.

According to AMW, we have the catch can right in that it goes IN to the top and OUT the side.

Another school of thought is to reverse that so you're pulling out the top through the screen. I think that's how rapidmotorsports has their catch can setup.

How did you guys mount the canister to the block?

Which of the three holes in the block did you use?

Thanks in advance.

Amw sells a bracket. It's the farthest left top and bottom holes.

Ok, this makes good sense to me... I agree!

I turned around valve boot, put it on the valley nipple, ran a hose to the top of the can, out the bottom with another hose, to a coupler, to the TB grommet.

I would think that it would HAVE to hit the top of the can first, so the steel filter would change the spray to drops that fall to the bottom of the can and would have to run up the can's sluice before exiting into the TB.



Here's a bender... wouldn't it be optimal to have 1 valve on each side??????

I agree. Here's the thread with it the other way. In defense of the deigner, it may have to be that way with THAT catch can.

https://ls1tech.com/forums/showthrea...ight=pcv+valve

Also in reference to the guy that asked about the bracket, I have the bracket that came with the AMW can and have it installed on the driver's side in front of the fuse box next to the radiator. The hose runs are long obviosuly and routed under the MAF.

I like your idea Steve of another PCV valve after it leaves the can, but I can say with my setup I get no oil in the intake.

Okay, here's another question. The PCV valve has one side you can blow into, one side you cant. Does the side you can blow into go toward the valley (LS6) or toward the intake?

I believe flow is allowed in(valley to TB) from the little end of the boot, which is the big end of the valve, if that makes sense. Someone correct me if I'm wrong. I have a 50-50 chance.

I have often wondered how it would work using the top as the outlet

I've used the top as the outlet, and it didn't make a difference.
