So I have my Evo 0 I am still working on and I have a breather catch can (wrong type for this car) that was included by the previous owner. I'm a poor teenager that doesn't want to spend $15-30 on a branded/ebay catch can and I don't know how to do any type of fabrication, I know oil catch cans are easy to fab. I was wondering if I could simply take off the air filter from the top of the catch can and hose clamp something over the hole to make it a sealed catch can, like a piece of rubber tubing and obviously tighten the hose clamp a lot so it doesn't get sucked in. It has two hose ports which is what I need, it's just that I don't need the breather. would this cause any air flow problems, or affect the way the oil gets caught in the inner filters?
