OK, ive taken off the air filter and checked for oil in the intake section of the turbo (ive been reading up ). Theres no oil but it does seem quite sooty. There is play in the propeller shaft but it is very little, mybe 1/2mm at the most. The propeller spins freely and doesnt catch at all. At the underneath of the turbo i noticed an orange colour substance building up on and around what i think is the oil outlet but i dont know if this is normal or not. Where the turbo bolts on to the manafold there is a white substance building up around the gaskets again im not sure if this is normal. Im considering taking the turbo off completly for more inspection but not sure if theres anything i should do first, or anything i would need to have in order to put it back on i.e new gaskets, seals etc.. any coments more than welcome cheers Guys!!

P.S does the turbo need to be opened up in order to inspect the oil seals?
