Should I be concerned?
I have a very slight oil leak on the lower oil hose to the oil cooler. Not enough to drip on the ground. Seems to be coming from the metal-to-rubber compression fitting at the oil cooler end. Just a little oil running down the metal line and onto the cooler fitting. Should I be concerned about this? They don't normally "catastrophically fail" do they? Thanks, RT

If it has only started to 'sweat' you have some time (unles you lose a belt, which is a very good point, but hopefully will never happen). I drove my car for 15-20k with my upper hose doing the exact same thing, before I decided to change it. I could have left it for longer, but had it in the shop, so got it done.
I used 15wt dino oil... not sure what synth might do to these hoses, but I know that in my ZR2, which is notorious for seeping oil cooler hoses at the same spot, when I went from penzoil to mobil 1 5w-30, the hose started seeping, and has since... (and my truck was ok from when new, and it still seeps for the last 15k) JMH
