Turbo oil leak - gasket?

I've been stripping the turbo side on my car to find the oil leak. I was going to take the whole turbo off so I can properly clean it all up and get the fire extinguisher powder off everything but I'm buggered if I can see how to get at the last 9/16ths nut that holds the turbo to the manifold.

 

I've found the oil leak. It's leaking from where the oil return pipe joins the turbo body. The flexi hose screws up to an alloy part that is bolted to the underside of the centre housing - the leak is either coming from the hose joint or from the joint between that alloy part and the centre housing body.

I was suprised to see that there was no gasket between the alloy piece and the centre housing. Is there supposed to be?

Yeah there is supposed to be a gasket there :)

 

And you have to take the intake housing off, then the centre section out of the exhaust housing, and then unbolt the exhaust housing from the manifold because you can finally reach the bolt.

 

Getting the centre cartridge out of the exhaust housing can be a bitch, as it force fits because of the heat. Blocks of wood and taps from hammers helps.

Bollocks. No wonder the fecker is leaking then. Any idea where I get a gasket? I suppose they are different for different model turbos, right?

Oh joy, that sounds like a right laugh
