For the last 4 days on starting my 200tdi defender the turbo sound has changed, it now sounds like an electric motor whine rather than the usual woosh sound, the new sound gets far weaker and barely noticable once the engine has warmed up and still boosts to around 14psi. I took the inlet hose off the turbo to have a look and there is a bit of upwards and downwards play in the bearings and the light oil around the housing seems to have been disturbed at the bottom making me think the blades have dropped and could be brushing the ali case, is this a likely scenario?
If my turbo is indeed knackered does anyone have a good condition one for sale or know of a cheapish reconditioner in the UK?
Thanks, Fergus
