Replaced the turbo oil line, gasket. Clamp. And o-ring on the T5

Chassis break on the oil line, be careful ordering.

These parts hide under lubrication system , not turbocharger category in Volvo parts apps

Tools and procedure

5 mm hex head M4 bolt hold flange of pipe to turbo
O-ring end into the crankcase is a hand press fit.
m6 ( 10mm socket) to release flange screw and nut on clamp which holds oil line and coolant line together
Vice grip to help release oil line


Turbo flange bolts released easily
Clamp bolts were very tough

To reinstall, put one bolt through gasket, raise pipe and tool together, hand thread onebolt. Use tang on gasket to set gasket into right place, insert other bolt

Torque on M4 ..I used 6 Nm as I couldn’t find a spec, so used a nominal M4 spec.

Look at all that material wasted on the gasket - why that big tang?

Look at the cool inspection ports for the piston oil jets - bet you didn't know that.

Let me know if this cures your intermittent leak on the rear of the block please =)

Hope so!

One thing about the diagram above. There is a deceptive line between the oil supply line ( double banjo bolt fittings) and the return line (simple flange and flat gasket ) that implies the banjo somehow mates to the flange..it does not These two connections are independent

Redlined it for clarity

I replaced the gasket a few weeks ago on mine, easy job once the car is on ramps and it fixed one of my oil leaks

I'd recommend fixing it asap when it leaks, p.o drove mine with the leak for a year and since it drops on the driveshaft it covers the whole engine bay in oil :roll:

Well, power washed the underneath and have a hot run on Tuesday next week, so we will know if that has helped the wet engine back (right side) problem shortly....

Follow up

This completely fixed this

Those M4, 5 mm hex head bolts can be a pain to release. One of them is obstructed by the drain pipe and is best done with a long hex bit.

Alternatively, release the oil line clamps so that you can pivot the blocking drain tube away from the fastener path, first
