This hose which appears to take coolant from the auxiliary radiator and connect it with the big engine to radiator hose is swelling from oil and leaking under it onto engine oil cooler hose part # 17117521066. The problem I'm having is discerning where the oil is coming from- is it coming from the power steering fluid cooler push lock connections, or is it coming from the charge air temperature sensor hole... I scanned my camera by the temp sensor hole one day and I could see the gap where the o ring wasn't sealing the hole, and as I still have plenty of oil coming through my intercooler, I'm thinking it's mostly coming from here.

Has anyone else noticed this problem? If so what steps did you take to fix this? I know I'm going to need a new temp sensor o ring or just replace the part completely which is what I'm leaking towards, then I may get the hose and hope that the power steering lines just aren't as bad as I think they may be. Those run quite a bit more than other parts in this area. If anyone has any advice I thank you prematurely.
