all the vacuum hoses has been sorted out except the ISCV intake and the one at the back of rocker cover, which the rocker cover one I can block it no problem, but the ISCV one I cannot block it as I tried yesterday and the engine would stall, so should I connect the ISCV inlet and the rocker cover one together with a oil breather in between? any suggestion? also would like to know where do people hook up their oil catch can?
