Chevy & GMC Vans

so an oil leak raised its ugly head last night. the fitting at the top of the Radiator where tue clip goes into the threaded fitting. anyone dealt with this before ? any ideas i have not taken it apart yet . so any help would be awesome. Thx

I was able to take the clip off, and reclip it which solved my problem, but it could also be a hairline crack on the radiator itself which would mean replacing the radiator....so I suggest you take off the clip as they sometimes get loose. I didn't have to replace any orings or seals, I was able to just reclip it back on, the link below shows the clip I am talking about.
