1995 Chev Tahoe four wheel drive 51 000 miles.

Why do the oil cooler line hoses always seem to leak where the metal tube is crimped to the hose part. Are Dorman cooler line hoses as good as Delco? Look same to me. Should I have the 2 fittings with the plastic clip replaced that hold the line replaced or just get the 2 lines. Do the lines come with clips or do you buy them separate?

I think this is the 3 rd set of these, last ones made 3.5 years...seems like a poor design.

Thank You
