Now if you have already read, the Pros and cons of deleting the PCV here (http://www.trafficjams.ca/Performance/PCVProsCons.htm) then its clear this system must stay in place. Now, the other discussion is people adding atmosphere filters on either the end of the catch can, the valve cover or replacement of the oil cap. If your SD or MAF tuned and have this ‘air leak’ tuned in throughout the rpm and engine load (because PCV valve is not open all the time), then you are good, otherwise, your loosing potential efficiency, therefore power and economy and really shouldn’t be running an open air filter on any part of the PCV system. Remember, on a closed system, opening to the atmosphere gives a 3/8” hose air to bypass the metered air the ECM calculates for combustion. Your volumetric efficiency will be incorrect and Im not a fan of those people that do it anyways and force the computer in closed loop to correct, it shifts all the tables and is NOT the proper means of approach.
Keeping the oil out of the air and in the intake track keeps your sensors clean, oil free, keeps the nice aftermarket intake clean and more importantly, avoids stoich variances and octane levels that oil vapors change.
I ordered the ‘split two piece system’ because the next phase is a procharger phase that requires TWO catch cans and will be showing you with check valves, PCV valve and the required tune.
This document is just a short step for installation of one for a stock car PCV system.
Lets look at the catch can itself.
There are many companies and self entrepreneurs that sell these oil catch cans. Many in my findings are just plain junk and are just empty cans. There is a science to this believe it or not.
Now, hands down this is the best catch can designer and manufacturer, period.
42 Draft Design is the company name, website here: http://www.42draftdesigns.com/categories/products/catchcans.html
I mean, a little dipstick for your can? That’s high class features. Notice the proper honeycomb mesh layers used.
So, if you’re up for spending 235US for a catch can, don’t bother looking anywhere else.
I strive to find the best product for the application.

Well, though its nice, I want something affordable but just as good.
Again, out of the dozens of cans I looked at, there is one that actually functions well and is priced very well.
The Saikou Michi Company specializes in mechanical design, metal fabrication, and general machining consulting.
Amazing service, fast shipping and very decent weld / metal quality.
Braided nylon hose not included.
Very straight forward installation, all you need is a 10mm socket and two 11mm wrenches (7/16”).
For now, I decided to mount the non-logo catch can on the fan assembly bolt on the passenger side. This of course will need to be re-located when the intercooler piping, procharger goes on.
I think the pictures will be self explanatory, enjoy.
REMEMBER the top of the catch can is the DIRTY side…
I have the braided nylon on the clean side.
It does appear to drain the catch can; there is little room, so removal of the can will be necessary.
