guess that is a livable repair at 170,000 miles
but have you checked all the stuff up top to make sure it is the oil cooler?
mine has leaked from the big plastic part that attaches to the turbo and holds the orange seal
the seals leak but often the plastic piece is cracked and that is where the leak comes from
you have to disconnect that from the air filter housings, pull it all out and check it over good
the first motor i had was really cracked badly, the second one it was micro cracks all around the part that holds the seal
the new part is updated
and also the small orange seal on hose next to all this leaks, it was leaking on my GL, i change both orange seals about every 12-15,000 miles
sooner if anything leaks
would be great if it was one of these things and not the oil cooler, much easier to do
