Turbo oil leak

Post by Fiodor » Fri Dec 20, 2019 7:32 am

I found out that I had a leak on my turbo, most likely from the oil return line with the nut facing the firewall.
Do you know what the part number is ?

Bonjour, Fiodor

I think the rear facing nut is coolant, the top nut os the oil line - see the diagram attached. You can tell the coolant lines by the rubber hoses connected to the coolant pipe of course.

The bottom metal line, about 2 cm diameter, is the oil return line with a paper gasket.

We didn't get the V70 model in 1997 in NA so I am using the 1998 V70parts list from here..
