Had a look but its all a bit confusing as I dont know what its called :doh:
Found this picture on another site and its sorted one gasket part number but im still stumped on the other.
LR Centre Ltd - 300TDi Oil,Air,Fuel Filters with Associated Parts-Dis
Im going to change ERR3283 incase that is gone aswell but the main O ring and seal im after is between ERC5923 and ERR2241
Maybe it comes with one of those parts ?
