OIL COOLER LINE LEAKS, HOW TO FIX

1994 GMC Sierra • 126,000 miles

Replaced engine oil cooler lines but the bottom inlet still leaks. The plastic sleeve has too much movement. Tried to replace the sleeve, but still is loose. Is there a permanent fix/

It sounds like that one line is bad. I would take it back and warranty it for a new one.
