Instead of paying $100-$200 for a name brand catch can, I decided to start a project of building my own from various parts and vendors, some of which I already owned.
I started off purchasing a generic catch can from amazon for around $25, then going to the local auto parts store and purchasing the correct size rubber hose to attach to the PCV valves and to the catch can. I believe I used 3/8" diameter hose. I purchased copper tubing which I cut to size and used JB Weld to hold together, although I shouldve brazed the metals together (copper to copper and copper to aluminum can). I wrapped the drilled copper tubing in steel wool. All of this created a baffle for the oil vapors to be trapped inside the previously empty can.
I then attached the baffled can to the drivers side of the engine because that was basically the only free space I could find to mount it. On the passengers side, I used a K&N breather filter.
After about a month or so of using this setup, the catch can caught a decent amount of oil vapor just from the drivers side! While checking to see how much was caught, I also realized that the JB Weld did not hold up against the anodized aluminum can with the high temperature and oil vapors. It had completely broken off and was just hanging around inside the can, (i.e. no more baffle).
I decided it was time to figure out how incorporate the passengers side to my design. I did this by drilling out a 3/4" hole on the lid of the catch can because that is the same diameter as the bottom of the K&N breather. I fitted the breather in and it was very snug. I sealed it by using silicon. I routed 3/8" rubber hose from the passengers side to the other inlet of the catch can. I now have both sides of the engine's PCV valves hooked up to the catch can with a K&N filter as a breather on top. For a baffle now, I just filled the can with steel wool to provide some type of baffle to catch the oil vapors.
All in, I spent a total of ~$40-$50 on new material for this entire project.
