Oil leak near distributor?

Hi all,

This morning on the commute in, I blew out the water pump gasket. I was limping in to work as best I could, trying not to overheat the engine (the temp gauge managed to stay in the "safe range.")

At some point, oil started leaking from near the distributor. It is oil, not coolant (if I'd blown a head gasket because of overheating, there would be coolant, not oil, leaking out right?).

This is the 3RZ-FE (2.7L) engine with a manual transmission and 4WD.

I think there's been a minor leak coming from this vicinity for a while, and it just now "blew out" so that there's a lot of oil leaking now. I haven't had a chance to get it cleaned up and see where the leak is, but can anyone give me some guidance as to whether a leak near the distro is a common problem? Where should I look?

This old truck's got over 371,000 miles on it. It doesn't owe me a thing, but if it's relatively cheap and easy to get it up and running again, I'd like to do it (especially since I have to get it out of my office parking garage now).

Thanks.
