boost and valve cover venting i am running a carb'ed setup on my ls conversion, with a disc procharger-my question is the valve cover vent tubes-older gen 1 engines used pcv valves, which i used to tee off for the power brakes, and run a breather on the pass side v/c
the ls engines have 2 tubes, 1 each on their v/c's, but it looks like they dont use a valve-right now i have a hose from the carb to the brake booster, and tee'ed to the d/s valve cover tube, with the pass side open-but there is really no valve to stop the boost going into the d/s valve cover, kind of like a ck valve-i havent fired it yet, just trying to figure out how the engine is supposed to be vented-i thought of running the pass side into the air intake of the procharger, and use a filter on the d/s valve cover-under boost, i would still have some venting-any ideas, thanks
