So i was getting tired of my old catch can filling up every once and a while and spilling over into the engine bay, i decided to make a new one. As long as you have a welder this is pretty easy to make. The dimensions for the can are 6x4x7 and it fits right behind the windshield washer fluid. The part list is as follows:

Thin sheet metal
2 3/8 brass barbed fittings
1 drain valve
5 feet of 3/8 hose
2 small filters

Here are some pics:

Don't forget Andy, he's running turbo and there is more blowby. No sense in making the small Kobalt catch can if you have to empty it pretty often.

I believe that in the end, after it's touched up and polished it would look good. Good job on DIY. Cheap large catch cans can be gotten as low as $20 though, no name, and no time investment..

You just don't get the experience and pride though, if you buy one :).

How are you going to weld that brass barb to steel though?? If you don't seal it you will have a boost leak..

Damn that thing is huge like a battery box!
