I am so paranoid that when my lower line began weeping around the crimp I went:

and two weeks later I bought: motor mounts, two brand new oil cooler lines at the dealership, and a set of motor mount bolts, and a bunch of tools (LOT) to do the job. I found out that my lower nipple on the oil cooler was spun out, so I headed on ebay and bought a brand new Behr one for $160 less than retail, finally got it, installed it and was all set and good to go. I tried to see how much it would take to destroy the old hoses once I had them off....and I could not break them out of the crimps....they were still extremely strong

Those hoses are also VERY thick, you can saw half ways through them before you even get any oil leaking out....needless to say it was a heck of a job but I am glad I did it as now I don't have to worry about it for a looooong time. I also have no A/C belt

so I don't have to worry about that either.
