X35D turbo replacement / oil leak ???

[nikpottala]

I've been to two indy bmw mechanics who won't touch my X35D which leaves the dealer as my worst and only option.

I have oil leak on passenger side at the intercooler connection. The charge pipe and seal replacement seems straight forward from everything I've read aside from the cramped space and being under the car.

My concern is the quantity of oil I have leaking. I've cleaned the plastic belly cover and in 1 day of basic in-town driving it's saturated again and I have a dollar coin sized drip on cardboard overnight.

Has anyone replaced the turbo on these? I'm curious if my turbo has an oil seal leak internally and causing excessive oil to enter the boost hose? Sound plausible?

The last indy said the turbo replacement required all sorts of special tools but I want to know if its a DIY job? I think he was afraid of the diesel.

If I find excessive oil in the charge line when I attempt to replace those seals I may just want to replace the turbo to solve the issue once and for all as it seems like a bolt on item. Right?

Advice and instruction is welcome.

BTW its a 2009 with 121,000 miles.
