hey everybody, im in need of a catch can. I've seen a lot of options out there and i was wondering which ones people are goin for. they all look very similar. are most of them 2 chambered? my friend was telling me about someone that makes some, but i cant remember the name. something like drrx?
They are A few diff setups but I myself would either have a can I can service (element) or on that doesn't have a filter element. I have a friend with a fbody and he uses a eBay unfiltered can and I am supprised by the oil it catches.
If I understand the process, the "filter" is to trap vapors from leaving the catch can and entering the intake anyway. Without a "filter", the can isn't as efficient. The typical metal "filter" mesh is easy to clean...
I have the Elite Engineering Catch Can on my 1997 C5. It was a little expensive but in my opinion it is well worth the money. It is a very quality piece of equipment and very well designed. The top portion of the catch can is filled with a filter medium.

Reason: left out the filter part
Unfortunately, even a typical "metal mesh"-type filter will alow oil droplets in the sub-micron-20 micron range escape and slowly but surely coat the intake.
Any catch can that does not have a filter is essentially a liquid oil trap. Lots of airborne oil droplets sail unimpeded to the intake. This is like having an air intake filter with .1-inch holes in it. You'll catch the large stuff but plenty of small stuff will get past the "filter".
