Oil leaks

Another leak point that often get's missed is the alternator bracket bolt that goes into the foremost hole. It goes into oil. Put some RTV on it.
When that one leaks, it pretty much goes everywhere.

Pulling the pan in the car to replace the gasket is not feasible, except for a serious contortionist. Wait to do that with the engine out.

The timing set cover can be done. Read up on doing that in the articles section on dot org. Check your timing set while your there.
Get yourself one of the rubberized valve cover gaskets. Make sure the valve cover bolt holes are flat in the cover before reinstalling, and observe torque specs.
The oil pump has an O-ring under the outer plate and a gasket under the pump body itself. The engine must be lifted up to remove the pump. Until your ready to do that, leave it alone. Don't be tempted to tighten the pump plate bolts. The crusty old O-Ring will break, and then you'll get a bad leak.
The pump bypass has a copper crush washer under the cap. It should be checked.

Hope that helps!
