If it has only been a week since they worked on it I would think they would check over there work and identify the leak.

The first time I took the car back after they did the oil cooler therm gasket, they confirmed it wasn't that and it was the UTCG and VCG. not sure how easy it is to have a good visibility of the oil cooler therm without taking bunch of stuff out of the way. their response was pretty quick. took them like 10 mins to call me into the shop to show me the problem.

I ran my hand down along the oil cooler lines and indeed I got fresh oil on my hand from around the thermostat. it would be a huge mistake to not replace the o-rings when they did the gasket!!

is it the same amount of work to replace the two o-rings?

thank you.

I was just thinking, could the upper oil pan be leaking? would the oil end up at the bottom of the front diff cover?

It is only one bolt that holds the oil lines into the thermostat housing. It is the easiest one to get to. Once the bolt is out the lines are easily disconnected. A mirror could let you see it. It would take removing the fan, belt, and alternator to get to it I believe. The o-rings should be replaced at the same time as that gasket. It is still mostly a blind job. If you could confirm the o-rings were the source of the leak I think you would have an argument for them to replace them.
