Catch Can -- AOS/PCV System Installation

[Kiko]

Hello!

I thought that I would share my recent mod -- the installation of an AOS (Air/Oil Separator) system, or, in other words a "Catch Can - PCV system".

Until now, I ran with two breathers -- one on each valve cover. These were Billet Specialties with washable filter elements. Driver side had a breather with PCV in the valve cover with a 5/8" hose to the base of the carb. Passenger side had just a breather inserted in the valve cover. Having done some research on Catch Cans, it seemed like a good idea to install such a system to help the engine breath better and eliminate foul odors. There are numerous systems on the market -- all of them do their job more-or-less. Cost is not a guarantee for quality nor functionality. I chose the Mighty Mouse offering due to its esthetic appeal, "made in the US" and positive reviews.

Attached are some pics of the install. I'd like to get feedback/comments regarding your experiences (if any) with Catch Cans, as well as input regarding my install -- mistakes, options, or anything else.

Thanks,

Well, I just kind of think catch cans might be a great companion to spark plug 'non- foulers' .

Is it catching oil on your engine?

I did something similar last year.
I already had one of the ME Wagner Dual Flow adjustable PCV valves installed and tuned ;

Dual Flow Adjustable PCV Valve – M/E Wagner Performance Products

Then I added a Trick Flow catch can;

Trick Flow® PCV Air/Oil Separators TFS-51400850

It does catch oil,although it didnt collect a whole lot,so I'm guessing that mine is a tight engine.

Did you use a vacuum gauge to set up the M/E Wagner valve?

I haven't driven with it all that much, so can't say at this time how well it's performing. I'll let you know as time goes by and I put more miles on that engine.

I ran a catch can on a 5.3 in a GM truck
Here was my first drain amount and what happened. After a day you can see the separation. Final pic was a surprise as to what it did to the container

I don’t even want to think about how corrosive that is to metal if it can degrade plastic so easily.
