Oily Turbo on Fourtrak '98 TDX


Hi, does anybody have any advice before I investigate oil around the turbo compressor exit pipe on my 1998 Fourtrak TDX which is dripping onto the oil filter. I'm hoping it's only a blocked oil drain but would appreciate any advice on any problems I need to look for while stripping down for a closer look, and any tips for removing and cleaning the drain pipe. Many thanks.
