Personally , I would wash her down, brake kleen the general area you think the leak is coming from, wipe it down and fire her up while she's on the hoist/ramps and watch close.

I like the latter comment; not so much the former.

Edit: I misidentified the connectors, so the following doesn't apply in this case. See 1slow370's comment below. Sorry about that.
The main reason compression tubing fittings fail is because of improper installation - usually over-tightening. A close second is over-tightening during reassembly. Follow the manufacturer's procedure for installing the fittings (usually hand-tight plus 1/8 to 1/2 turn depending on size) and you will have very few leaks. When re-assembling, just snug the nut up - it doesn't have to be as tight as many people think.

Needing to bring this back up again. My car recently had it's 90 000 kilometer service (or 56k miles). The dealership said they found oil on a spark plug while replacing it as part of the service. They advised that the valve cover gasket needs to be replaced, however, the parts are only set to arrive 3rd week in December. I wanted to know if the vehicle is safe to be driven around until the parts arrive. Thanks
