Default V70 T5 engine oil leak

Hi all,

My V70 T5 has started to drip oil, and smells of burning rubber/oil after a run.

When I check and top up the engine oil from time to time, I haven't been seeing any dramatic change, so I thought it might be ATF. ATF levels are normal.

But getting down underneath today, I can see it is engine oil not ATF.
The whole subframe, engine and gearbox is wet with oil, but mainly on the gearbox side.
There is the usual seepage around the bottom of the intercooler.

Photos attached.

As far as I can see the turbo is completely dry, and there are no leaks from the turbo oil return pipe (at either end).

The oil is dripping from a bit of the engine casting that is quite high up, just to the left side of the exhaust manifold, and just above the bottom of the turbo and also just above that metal heating tube that runs across the back of the engine.

Is it difficult to see or to get at from below or from above.

I am trying to think what is up there, that might be leaking? When I have a chance I will take off the spark plugs cover plate and see if there is much oil up there.

Thanks
Steve
