Replace the remote oil filter lines as soon as possible. They may last for a
while with a slight leak, even years like mine did, or they could go out
tomorrow. The leak will eventually get much worse and as a worst-case
scenario, the line could rupture. I left one hell of a stain on our old
driveway and in a couple of parking lots when my slow leak suddenly got
worse over a week or so. I was lucky they didn't blow completely.

Replacing them isn't as scary as it looks if you don't mind removing an
engine mount and jacking the engine up slightly. Oh and if you go with OEM
parts keep an eye out on the ends of the lines. My old ones had recesses for
o-rings (another common leaking point) which the new ones did not. I used
special washers with an o-ring attached to the ID. We call 'em threadseals
at work, I've seen them in the oil drain plug isle in parts stores.
