hi, again. i noticed last week one of my plastic pipes had snapped clean off both ends with oil deposits around the connections. im not sure what the pipe does but the car appeared to run fine. i replaced the pipe this afternoon(pic 1), 35 quid! upon fitting i noticed, looking at the engine head on, at the bottom of the pipe there is a t piece then runs left to a plastic curved piece (pic 2, taken from my mates 20v golf) mine is not connected. it doesnt look like it has snapped off but it doesnt fit back on. could anybody enlighten me as to what this pipework does and if the disconnected pipe needs replacing or how to reattatch it. any help again will be very much appreciated.
