Catch tank ideas
Hey guys, I searched and couldn't find any solid info. Could you that have made/installed catch tanks successfully please give me some help on the best solution that will give me reusable oil? I read that Tony made one, but I couldn't find it with a search. Thanks

Hey Mark,

Try typing in the word "separator" as your search term, I think you'll come up with more hits than "catch tank".
There were a few different posts on the subject over the last year.

Getting usable oil is a difficult trick. There's so much water vapor in the blow-by that the oil will be contaminated. If the blow-by was at a constant rate and temp one couid be engineered, but the cars aren't used like that. The separator needs to be sized for the hgihest flow rate so at slow rates the water will condense and precipitate out.
At the track the drainage on my car looks like new oil. On the street it looks like 95% water.
I recently changed my separator to a pretty simple home-made unit. The housing is a (used) water filter. An under-sink model for 1 foot (abouts) cylinder filter elements. Thats got two ports on it. One comes out it the middle on the inside. There's a piece of hose (3/4" by 8") clamped on to that force the incoming mix towards the bottom. The body is stuffed with copper puff ***** like for scrubbing pots. At the bottom, on the side, is the drain which is just an NPT-to-1/4" hose fitting tapped in.
The separator sits in the left fender where the cruise control was. It's clamped to the wall. The inlet line goes to the stock vent fitting on the oil filler. The outlet from the separator runs to the air box where there is a fitting on the lower half. The unit isn't just vented as that would stink around town.
The drain line runs to a valve that's hidden at the bottom of the fender. The handle and a bit of tube stick out so it can be drained easily.
The old hose for the PCV system is capped and otherwise left in place. I can go back to stock if the system starts to leak or whatever.
Anyways, about $15 for hoses, fittings and a valve. Had the housing laying around. That'd be another $20. A nice separator loks to be $75 or more. Looking on them (like eBay) check the sizes. Lots are really small like 6" by 3".
