http://www.dsmtuners.com/forums/articles-parts-fabrication/263685-2-oil-catch-cans-setup.html. I fabbed up a couple catch cans, but want to use one. Currently I have one catch can from the breather to the catch can, then other hose back to the intake. Can I. . . Plug the intake hole for the breather line, and plug the breather into one catch can port, and plug the pvc with a check valve into the other fitting, and of course add 2 filters on the other two fittings? What would I do with the existing hole in the intake that the pvc pipe originally went to? What could I block it off with?
