Oil Leak Repairs

[Hamersley]

Hi D4 Drivers,
I wondered if anyone has had to replace engine oil cooler to fix a leak they say is the coolers gasket and quoted $900?
Also any info on leak from L/H turbo drain?
Much appreciated what I have gleaned from this great site.

Mine had a leak into the V of the engine which they thought was the oil cooler pipe, which appeared to be porous. They replaced mine with a free pipe that they didn't use off another car's replacement oil cooler. They also initially thought it was the rear main seal, but that has not been fixed and the main oil leak has stopped.


The worst leak that I had was failed O rings on the power steering pipes into the rack. This was due to the connector being loose, causing the O ring to fail on the very rough roads I had just been on. This looked like a major engine oil leak also until I saw that it wasn't engine oil and the power steering ran out of oil. It was coming from the same area as the engine oil leaks I had previously because of all the underbody guards so I was confused for a while.
