Thanks bram for the detailed pic, I know where they all go now, my car is a 3 dr with a 200block and 4x4 head and someone has kindly already welded the oil return off a 4x4 into my 2wd sump, so I can pipe it all up using exhaust side instead of rocker cover etc but my next problem is melnei engineering won't answer their phone for the 2 block adaptors I need!!! The vent to the atmosphere won't (shouldn't) leak oil as the bailey tank is a separator and that should only be vapour .
