Im looking at buying a catch can for my 08 vette. I see CCA has some pretty decent prices. But what is the best catch can out there.

One that looks like this:But since it doesn't look cool it's not too popular

If you Google Conceptual Polymer you will find something similar but a bit more professional. The key design issue is to swirl the air inside the catch can, this will separate the oil from the air better than a simple static filter (like a mesh used in practically all the others). Like a centrifuge but with no moving parts. It's the same concept as the air/oil separator on air compressors and other industrial equipment.

Its a drip catcher, I wouldn't over think this one,

Mark2009, thats what they use in Manufacturing and it works great, plus you cna see the bowl. in my industry its called a filter regulator

ok ii did have one of these on my cobalt turbo but just thought I wouldn't cheap out on the vette lol

I got mine form Cajun, good guy

Do you guys have any install pictures?

Mark2009

What is generally marketed as a catch can is indeed a drip catcher. However, a true air/oil separator -- and the one pictured contains no regulator function -- is needed if you want to do the best job of keeping oil out of the intake manifold.

Even if it is cheaper

timd38

Have that one also.

Z51vette88

how does it, work any complaints?

timd38

My works fine. No oil in the intake.

Z51vette88

perfect thanks guys

To make any catch can more effective, mount it someplace where it is cooler. This helps cool the vapor so the oil can condense and fall out of vapor. I mounted mine way up front and also used a copper line on the intake side. By doing these two things I virtually eliminated all oil vapor entering the intake tract. The can stays dramatically cooler as is the return line to the intake.

It's also amazing at how clean my exhaust tips stay now that I did this. I can drive 1,000 miles and my tips still look shiny. Before I moved the can and added the copper line they used to get black MUCH sooner than they do now.

I had this setup on my 406ci 85, it worked fine, I liked seeing the glass bowl oil level, with that said, "best" is a relative word, there is no way to measure the micron level of filtration, so this is why I say don't overthink it

timd38

Makes sense. What does the copper line do that helps?

Thanks!

JRHAWK9

The copper line adds to the heat dissipation of the vapor. Think of it has a heat sink. That copper line gets hot to the touch while the can and return rubber line are warm at best. Anything you can do to cool the vapor will help the oil fall out and condense.

Here we go again! Do a simple search and there are loads of good reads with discussions. As far as what is best, well........

These are a few of my attempts to improve with what I have at where it sits, not everything is shown in details but you might get the idea:

Z51vette88

thanks for the help, I understand now

VICTORF; where did you get that heat sink on your can? I would like to do that too!

victorf

There are two. The one at top for the incoming was something I made, then, mirror polished to resist corrosion.



The one on the reservoir, was modified from an commercially made, normally used by attaching to an existing oil filter housing, to aid, for the purpose of passive heat radiating.
