PCV catchcan
https://ls1tech.com/forums/generation-iii-internal-engine/512297-found-while-changing-pcv-valve.html
since my car is an 02 SS with the LS6 intake, do I need one of these catch cans or did gm fix that problem with the new LS6?
also, if i do need one, i can just go buy that $12 thing from home depot, hook up the 2 hoses to it, and thats it? nothing more complicated?
• 21 SCFM flow capacity @ 90 PSI
• 150 PSI Maximum Pressure
for a few dollars more they have ones that say
• 57 SCFM flow capacity @ 90 PSI
• 250 PSI Maximum Pressure
i have no idea what "scfm flow capacity" is but my question is would the more expensive ones do a better job of filtering out the oil than the cheaper ones? also, how pressurized is the air that will be flowing in to it? since these are pretty powerful engines would the air flow ever exceed the 150 psi rating of the cheaper can?
But to answer your questions anyway... Even with the LS6 intake it couldn't hurt to try the cheap oil separator/catchcan mod. Just stick with the cheap one. No need for the more expensive, higher flow one. I don't have the part number for the Husky one, but the part number of the Campbell-Hausfeld one that I'm using is MP513810. I think the Husky one looks nicer...unfortunately, they didn't have any in stock when I was looking for one. The SCFM flow capacity is so you can match the proper filter to your air compressor setup. When you buy air tools they have a SCFM rating...e.g. a die grinder might require 3.5 SCFM @ 90 psi. You would want to hook the die grinder up to an air compressor that would provide at least 3.5 SCFM @ 90 psi in order for the die grinder to work at it's peak efficiency. Long story short, I don't think you'll be running those kind of flow rates through the hoses that connect to this type of "catchcan" setup that utilizes the water/oil separator.
