If distributor and power steering fluid and valve cover is leaking, can you still drive your car?

Go for it. Just bring some extra fluids with you and check the levels when you stop for gas. 

No! the power steering can get you by but you'll have to use your own strength to maneuver the car. The distributer will cause misfiring--backfiring. The leaking oil valve cover will lead to a possible engine damage due to losing oil by the time you arrive to your location. 

Kieth: Production cars  had electronic ignition in '72; but Still used distributor. Our '78 El Camino did. So did the '80. Even an '86 Toyota did.  Its just that Most that went to el. ignition put Coil inside distributor cap, so no coil wire.

 Last production car with distributor was 2008.

Please get your car fixed.  Or get a rental car.

A distributor contains no fluid and can't leak. Also, unless you have a very old car, it probably doesn't have a distributor.

Do not drive the car, have the car towed. Leaking power steering fluid overheating would mean disaster.

With all of those problems, you should buy an AAA membership.  Automobile Club of America supplies tow trucks anywhere needed.

Keep an eye on your fluid levels whenever you stop somewhere, and replace any fluids as necessary. Distributor? How old is your car? Since everything went to electronic ignition, there hasn't been a distributor.

Depends on the severity of the leak...
