Have bought a second hand engine, got all pipes sused out but have noticed tat the previous owner has taken away the swirl pot and ran the pipe from the sump breather to the rocker cover. The only problem is there is an extra pipe from the t piece i cant find a place for. Any ideas. One of the ports at the back of the inlet manifold has been blanked over too. Perhaps the original place for the pipe? Bit of a puzzle
