DIY catch can for $27 and a little time...
I’m about to buy a catch can, but was on the verge of building one. So, I figured I’d go ahead and build it to share with those that may not have the budget to buy (they are quite expensive). I decided to build one using materials available at any hardware store using a few simple tools.
I’ve used this design in the past with good success, it will serve the purposes of most anyone and will collect as much crank case goop as many commercial ones. The Design Basically the design is a can that's about 6" tall and 2.5" in diameter. At the top there is an inlet nozzle and outlet nozzle. On the bottom there's a drain pet****. On the output end of the inlet nozzle a cross drilled metal tube is attached that serves two purposes,
The Material The body of the can will be made of three PVC fittings, coupled together with short pieces of PVC pipe to make it appear as seamless as possible. PVC has a melting point somewhere between 320 and 680 degrees Fahrenheit (depending on the quality of the raw material), which should be fine for most applications but care should be taken to mount the can as far away from the engine as possible. An advantage of PVC over a metal container is that it's a poor heat conductor, this allows the can to maintain a significant temperature differential internally relative to the engine compartment. This will enhance the can's ability to condense the crank case engine vapors. In the following picture you'll see the parts/items needed to make your catch can, they are:
The Tools You'll need the following tools,
Making the Body The body of the catch can consists of the two PVC pipe caps coupled to the PVC pipe coupler using the thin walled 2” OD PVC pipe.
1. On one end, drill two 7/16” diameter holes on the cylinder’s centerline. These holes should be separated by about 1.5”. 2. On the opposite end of the cylinder drill one 7/16” diameter hole directly in the center. 3. Using the 1/4” NPT 18 tap, tap threads in the three holes you just drilled. 4. Using compressed air, or your mouth, blow the inside of the cylinder clean. Making the Condenser Tube The condenser tube is fastened to one of the inlet nozzles (i.e., 3/8" x 1/4" Bronze Hose Barb Elbow)via 1/8“ NPT threads, these threads need to be tapped into the nozzle.
Assembling the Parts

It looks rough w/o paint, but the semi-gloss black paint makes it look very nice. I'll post pictures of it painted soon, along with the mounting bracket construction.

Nice work! You have the correct principals so I expect it to work pretty decent. Go grab a clear glass inline fuel filter and instal it inline between the outlet and the intake manifold vacuum and see if any (or how much) is getting pulled through.
