After searching on oil separators/ catch cans I am still unclear about hose routing. Do both DS and PS pcv valves tee into one hose to enter oil separator/ catch can and exit to either the intake before TB or after TB, meaning one would have to be blocked since there are two. I was also wondering if an oil filter relocation unit might serve as a suitable oil separator/ catch can mounted upright "somewhere in there". Thanks in advance for any and all input.
