I've searched around and I've seen a bunch of posts about the oil cooler line hoses themselves leaking at the crimps, but my issue seems to be where the oil cooler line goes into the fitting on the radiator. I do have the e-clip on there as well. Neither line is missing the clip.
Lately there's been a nice oil leak under the blazer in the driver's side front end. I traced it down to the connection between the oil cooler line and the radiator. The upper line is tight when it goes into the radiator with the clip, but the lower line is very loose and i can push it in and out about a 1/16th of an inch. Below this fitting there's a nice collection of fresh oil.
Are there any gaskets in there that could go bad? Or is it just a metal on metal seal(which seems very strange) and is held on there by the e-clip?
I pulled off the good and tight upper line and did not see any type of gasket on cooler line. I couldn't see inside the other side that goes into the radiator.
The hose itself looks good and so do the crimps. So if all i need is a gasket that'd be great. I don't mind spending the money on a full set of new front lines like the link the have below as long as it comes with the fittings that go into the radiator as well because i'm not sure if that side has been enlarged from all the moving around of the cooler line in it:
Any advice or direction would be great.
