Cyanidesid Posted May 7, 2016 Share Posted May 7, 2016 Hi guys and gals I'm new to all this so this may be a stupid question. i am currently doing a td04 conversion on my 96 ep91 and there is a pipe coming from the rocker cover to the intake manifold what's it for ? And could I take it off the mani and put it to a catch tank? Quote Link to post Share on other sites
5e colin Posted May 7, 2016 Share Posted May 7, 2016 (edited) leave as is for now as you seem to have only 1 feed on the catch tank ?? is there 2 filters on it ??? if so plum it in that feed its the positive crankcase ventilation valve ( gets rid of back pressure do not block it ) Edited May 7, 2016 by 5e colin Quote Link to post Share on other sites
