Caramanos2000 Posted January 13, 2009 Share Posted January 13, 2009 (edited) Ok guys read about it some on here and came up with this design to build it cheap:banana: more on how to install it later. Theory is crankcase gases enter the bottom and the oil condenses out as it enters a series of baffles, in this case coarse steel wool. Materials: 140 round paintball tube $2 2 of: 1/2" L shaped fittings male threads on one side, slip conector on the other $1.60 4 Steel wool sponges $1.68 6 of 1" screws $0.18 Chicken Wire -Free in my case Spare wire and Silicone/epoxy Begin my marking 2 holes on the outside of the container the size of your male threaded L fittings. One should be about 2" from the bottom and the other about 2" from the top. The bottom will be the input, the top will be the output to the intake. Make them slightly smaller so they can screw into the plastic. You can drill or even melt the plastic, make sure to go in small increments so you dont over bore your hole Next screw your fittings into the plastic and head for your car so you can find the correct orientation for your particular installation. Make sure you san and remove any plastic debris. Dont want any in your combustion chamber lol Drill 3 holes the size of your screws in a sort of tripod orientation about 1/2" above your bottom fitting, do the same at the top fitting except this time drill them below the fitting. The purpose of the screws is to retain a grille of some sort to avoid getting the wool close to the outlets on the consensator. I used chicken wire, I also made a handle for the bottom grille out of spare wire. This way it can be easily removed for cleaning. Put your bottom 3 screws in and place the grille on the top of them like so: Place the 4 coarse steel wool pads on top of the grille (I dont suggest using fine wool as its easier to suck into the engine, just to be safe) Next place your mesh directly onto the steel wool and insert the top 3 screws, this should keep the grille from popping upwards. It should also keep the wool in its place. Thats pretty much it. If you made my mistake and over bored the holes you can add some rtv or some epoxy to the thread of your fittings to make them snug and air tight. These paintball ammunition "pods" are pretty air tight, however I will make a gasket out of hot glue that will be airtight when closed and disposable when opened for cleaning. I will post more pics later of installation and the muck it collects.:banana: Do I paint it to look stock? or do I go crazy and do lime green or something? lol Edited January 13, 2009 by Caramanos2000 Link to comment Share on other sites More sharing options...
The Scooby Posted January 13, 2009 Share Posted January 13, 2009 so its a oil catch can, why not just buy a a water/air separator for a air system from a shop compressor, usually $7 and toss it inline and your done. Link to comment Share on other sites More sharing options...
Caramanos2000 Posted January 13, 2009 Author Share Posted January 13, 2009 The design of an air water separator doesn't seem to be as effective as these units are quite small and doesn't really allow the gasses to cool or slow down much. It is sealed, has a filter and allows the un-burnt fuel vapor in the blow-by that the catch can would hold to be taken back into the intake Link to comment Share on other sites More sharing options...
Skip Posted January 13, 2009 Share Posted January 13, 2009 nice job on the pictures and all There is a line on turbo cars that connects to the MAF to turbo pipe. This line lets a lot of oil vapor enter the tube. One of these would be perfect placed in line with this hose. Link to comment Share on other sites More sharing options...
