Now im confused, i just saw a post 07softail posted.

PCV line from under the Throttle Body goes into the catch can and the outlet goes to the side of the intake manifold.

PCV side goes to the inlet, and outlet to manifold.

The line under the throttle body connects to the inlet on the catch can. The outlet hose connects to the side of the manifold.

Correct. Think about it like this:

If you place filter media in the provided area, you would want the dirty air from the throttle body to enter there (inlet) and exit through the suction side (outlet) going to the manifold.

Installed mine 3-1 and was somewhat startled by what I found in just a day of driving...

 

Here is by bracket... If anybody has access to a water jet, laser or HD plasma I can send you the file.

My last truck was an '05 Duramax

I blocked the EGR at 40k miles and added a finger stick (eliminated codes)

Sold that truck with 390k miles with the original injectors and still ran very strong and smooth. These mods are key to achieving higher mileages in my humble opinion. Thanks to all that provide the knowledge base here.

Wacko can you hear a suction sound under the hood now after installing the catch can. Just wondering after my install mine did.

I recently installed mine and I don't have any suction sounds. Is anyone adding any filter media or are you using the can empty?

I had some scotch brite pad in mine for filter took it out still had suction sound. I could hear the suction with the hood closed also.I used 3/8 fuel hose could be trying to suck together but couldn't find where it might be. Had the can mounted at the battery box and all hoses were hooked up correct.I also could hear a slight buzzing sound in the cab when starting off slowly.Took off hose put stock hose back on and all sound went away. I always have problems that no one else has oh well.

I do not have the suction sound and I am using Stainless Steel scouring pad material in the small chamber filter area. I would check for a vacuum leak at a connection. The quick disconnect fittings did go on further than I originally thought they needed to. I did catch it before I put the air box back on but I would check them first.

 

Fyi mine is a 6.2L

5.3L here all the connection were secure I checked all 6 conection points clean and dirty side (are secure and snaped in place) and felt around each one to see if it would make any differance in sound. I checked the can it self to make sure the inlet and outlet were clear and open. I loosened the dip stick in the can and pull up on it and it was very good suction there. My hose lenghts are 24 inches from the crackcase and 21 1/2 inches from the intake. I think the crankcase side is sucking to just enough to cause this and when it gets 90 degrees and its over 200 under the hood the hose is just going to be softer. If a go back with a can going to use trans oil cooler hose or hydraulic hose.

I was surprised at how much suction there is when the dip stick is opened. I used 3/8 Napa PCV tubing. Maybe since mine is further inboard and lower it is helping with the noise.

I do have a suction noise...but I can't hear it in the truck or after I shut the hood. I have Gates PVC hose and used thread tape on everything with a thread.

    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back. 
    • That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed. Why not updates as well, especially since some of those can be safety related also?
    • That's good to know, but I don't think I'll even be running them under 45 in the rear  unless it's on the sand or something but will only be for a short distance anyways!    I didn't read all the instructions in the booklet yet, but do you know let's say I set the rear psi on the placard to 45, will the warning light come on soon as it drops under 45 or is there a percentage it has to drop from the set value before the warning light is triggered?
    • That's bad.  Like, its probably destroying the stub axle the CV slides into.   Do you have a proper lift installed with differential lowering brackets?  Did you install AT4/Trail Boss factory CV axles?  
    • Hot? New Jersey? Today? I was working on my old 2000 Silverado 1500 today. Believe me, it was boiling hot today. As it has been.
