**** SOLVED! I'll post pictures after I finish for anyone who wants to see how it's set up!

Alright so after months of seemingly endless videos and pictures of people's catch can installs, I sacked up and bought a Motion Raceworks catch can. While the price difference compared to other cans is certainly one point that is not to be overlooked, I really could not be happier with the way it looks and the level of customer service that Motion Raceworks has. I gave them my year, make, model, and modifications done to the truck to figure out how it should be routed, they told me what I needed and sent everything to me in a matter of a few days. Upon attempting to install it (the first time... six months later) I realized that where I was attempting to run the lines to just simply would not work. - PCV Valve to catch can and intake manifold pcv port to catch can - The AN fittings were too large. According to Procharger's install instructions (without a catch can), they say to connect a 5/8" hose that loops the valve covers - then tee from the loop to another small 5/8" hose section that connects to a 90 degree fitting on the back of the filter for the Procharger. Thus, I was getting a fair amount of oil and etc. getting pushed right back through the Procharger and into the motor. Nonetheless, as you can see below, this is how I ran the catch can per the instructions given over the phone by both Motion Raceworks and Procharger.

I also included pictures to show the vacuum line from the intake manifold. Soon this will be rerouted (yet again) for another vacuum manifold so I can hook up my boost/vacuum gauge. Reason for this was that I must have bumped the previous vacuum line into the serpentine belt and it began cutting into the hose. Therefore it needed to be fixed in order to drive it.

According to both Motion Raceworks and Procharger during the catch can install, the PCV valve 'must be plugged'. You will see my attempt (or temporary solution) to plugging the valve below. I simply purchased a new PCV valve and kept the green cover on the port that came with the PCV valve. Do note, this is not an airtight seal. I am able to feel a very small amount of air moving from underneath the cover. It is likely that I will source a brass or aluminum plug to fit in place of where the PCV valve threads into the motor (I believe it's 5/8" but have yet to try with an actual fitting.) Before installing the catch can, I had the PCV valve just venting to the atmosphere with nothing connected to it and ran just fine despite continuing to see oil in my intake.

I then used a combination of 3/8" hose and 5/16" hose and 1/4" fittings to connect the intake manifold PCV port to the bypass valve. Procharger's install instructions say (without a catch can) to route a 3/8" hose from the PCV valve to a supplied vacuum manifold (that I lost when installing the cam) and the vacuum manifold is then routed to the pcv port on the intake manifold along with a 1/8" hose that is connected from the vacuum manifold to the bypass valve. Believe me if that sounds confusing, it looked just as confusing in the install instructions provided by Procharger.

Moral of the story is, Motion Raceworks catch can is designed to be connected to the ports on the valve covers. It was literally that simple.

Hopefully, if you are looking to install a Procharger or centrifugal supercharger and a catch can on your truck, that the pictures will help.

As far as installing the AN lines, I highly suggest purchasing aluminum blocks that fit into a vise and an adjustable AN wrench. I sourced them from Amazon. I marred up one of my fittings pretty good when I was attempting to use a normal adjustable wrench and resulted in me buying another $30 fitting to replace it. It was my first time messing with AN lines but now, I feel I want to replace everything I can with AN lines (I would if it weren't so gosh darn expensive!)

I know, I've been going on and on, so without further ado here are the pictures!
