Thread: blown 355 problem

Tweet

all going good except for oil leak. installed cranckcase vac kit. the one with the bungs welded into headers. breather on drivers valve cover. pass valve cover no breather. passenger header POURING oil out when running. any ideas anybody?

well the crank case e vac will not work if your running a EX are you ? you still needed breather s with it but they just do not work on the street .you are better off with two open breathers on the valve covers one on each side of the engine

no disrespect but what do you refer to as EX? can remove and add breather. and it has full exhaust. i loose 2 quarts in 60 feet a low rpm w/no boost. thanks

you can not use the vac pan breaters on a full EX .they have valves on the headers that screw on the niples you welded in the headers they will stay shut from the ex back pressure in the EX. the crank case will vent and will blow out any were it can.EX that would be EXHaust they just plane do not work. if you are loosing that much oil did you do a compression check. sound like a hole in the piston or burn down
