whenever I drain my Provent it's about 1/2 to 2/3's water so there's condensate there - and I'd expect the folks up north to see some freezing (not a problem in Austin)

Hi!

I have read through the posts and all I can tell is that somebody rigged their own catch tank and it gathered water and froze?
This worry was brought up before anybody tried out my OCC.
I have dealt with customers from all over the world, including Canada, Norway, and Iceland (cold places) and nobody has brought up these concerns or contacted me about any problems encountered.
This is new to me, but I do not want to minimize the concern. I just haven't encountered a situation where the system would accumulate so much moisture that it could freeze up solid.

If I can make a comment, the provent is a different system all together.
It is an air oil separator and whatever gunk is trapped is supposed to be returned to your oil pan. It has a very fine fabric filter which is more prone to clogging than stainless mesh..

My OCCs are a trap. The stainless mesh helps condense fumes and gunk and traps it in the occ so you can drain it. The mesh works like hundreds of tiny baffles but still allows good flow.

The 951 type occ happens to be the right size for the Jeep since the hose nipples are the 3/4"

I got mine today, it looks like a quality piece for the money. I gave it a good blow through the top nipple and it's got plenty of flow. I'd be surprised if you could really clog this thing solid with ice. I did a quick test-fit and it fits quite nicely next to the radiator - just enough room to sit it in there with clearance, but not so much room that you wished the filter was bigger.

I may take the easy route and just try drilling a hole and mounting it on the body next to the radiator with a self-tapping bolt. If that strips out, I can enlarge the hole and try a nutsert.

Hi again,

Thanks for your quick, replies.

One thing people in the forum are thinking of doing is putting the
device on the car and then routing the outlet side into a clear jar or
clear hose and run it for a few hundred miles in order to determine
how much oil vapor is actually being cleansed vs no device. The folks
in the forum are nothing if not thorough in their investigations.
Have you done this kind of testing on your product? Any tests or data
(beyond anecdotal evidence) you can provide would be very helpful.

In my own experiment to determine how much oil goo was actually coming
out of the hose, I rigged an 8" long 5" diameter clear can filled with
steel wool and a hole at one end. After 2,000 miles there was lots of
black goo caught inside - scary that there is so much of this stuff
otherwise going into my turbo! However, I did note that even with a
long can filled with steel wool - which has a great deal of surface
structure for condensation sites - there was still a fair amount of
oily vapor coming out when I revved it up. Besides the obvious
longevity issue, how would your can be more effective at removing the
oil vapor if it only has a series of mesh plates vs the thousands of hairs in a tightly packed can of steel wool?
Thanks!

Hi!

That sounds like excellent testing! What we did when we were working on this idea was to build a catch can prototype made out of lexan so we could see what was going on.
It did collect the goo, so we were satisfied with the test. After that we received alot of positive feedback from customers.
Almost all of our business is by word of mouth.
When you use fin type baffles, you are limited to the number you can place inside and have less surface area.
A normal catch can does collect some oil just because the fumes collect on the walls, but alot of it passes through unchecked.
That is why I like the mesh system. You can create alot of surface area and still allow good flow.
Of course, some fumes will make it through especially when you rev. The solid oils are what is more harmful to performance.
It would take a really large occ, with several layers of filtering and some active cooling to really stop all the fumes from making it through.

Chris, are you talking about under the fuses (driver's side)? It seemed like I'd need to remove the battery to remove the fuse holder which would make cleaning out the filter harder than I'd like.

Very nice! Mine's still in the box, but I did buy a self-tapping bolt to attach it. Do you have pictures of your install? Where did you use the tubing adapter you mention?
