Oil Leak

[jt24]

I have a 2011 duramax and it has develop an oil leak on the drivers side of the engine. I found drips hanging off what I believe is the engine oil cooler. Am I correct? If so is there O-rings that I can replace and how much of a job is it?? See example photo. Red arrow explains where the oil is dripping from. Thanks

yes that's part of the oil cooler.. should not be oil there as that's a coolant pipe. It's coming from above that more than likely

The oil cooler is in the filter housing.

Could it be power steering fluid?

Yep I looked again and now the oil isn't black. It is yellowish in color. I can also see a little of oil on the inside of the hood from the oil flying off the pulley. How many bolts are holding the pump?

Well it seems the shaft seal is bad and you can't get just the seal. GM must of got it from some where but I can't get one. I have checked numerous parts houses and implement dealers. It has a AC DELCO number but it comes with the ID to large. They want to sell me the whole pump for $245. Does anyone have any other options???
