ok so i have a 72 240z that i just swapped a rebuilt l26 into with 1971 round top su's the car is running awesome but something sorta weird is going on. the tube that comes out of the crank case to the pcv valve isn't exactly the same as on the l24 and their is a rubber line that went to it on the l24 that that is about the size as a vac advance hose that no longer has a place to hook up. it comes from the drivers side fender well. there is one hose coming in from the back of the car to a splitter and two coming out. the bottom one was never hooked up but the top one went to that crank case tube. now that this is not hooked up my breaks seem bad almost like the break boost is not hooked up. is this related? thanks in advance for any input
