My question is.. is there any problem with routing the two small nipples together? The heater core bypass also allow for the large pipes to connect so couldn't its two small nipples too? I've already done the coolant bypass for an NA however further along the reroute that leads behind the engine has developed a huge coolant leak from behind the engine on a small rubber hose I cannot comfortably reach. This is my daily and I cannot pull the engine. Is connecting the heater cores 8mm inlet and outlet nipples be okay?
