Probably sheer age. There are two things that can leak in the areas you refer to. First of course is that valve cover gasket. If it is leaking its no great challenge to replace it. If you are not mechanically inclined then take to to a competent garage and have it done. Of more difficult note is the camshaft seal which is at the top of the engine and a bit more difficult to replace. Once again you will probably want to have that done at a good garage. Best of luck.

Does the timing chain have to be removed when changing head gasket?

Although I am not a certified mechanic....hell or even a mechanic , I would say no unless the timing chain is in the way of the gasket replacement, you should be able to on most motors replace header gaskets without the removal of the timing chain. ( timing chains are usually involved with the cam/rod repair and or replacement and such)

What is a timing cover and gasket?

Typically, "timing cover and gasket" refers to timing chain (vice timing belt) equipped vehicles. Timing chains need oil from the engine for lubrication. To make this happen, there is an opening between the timing chain area and the valve camshaft area. The oil the flows into the timing chain area, then down into the oil pan. In order to keep the oil from spraying all over the rest of the engine (and having the engine break down from oil starvation), a metal 'timing cover' is installed over the timing chain and sprockets. Then, a 'gasket,' made of a soft, oil resistant material, goes between the timing chain cover and the engine block to prevent any leaks. The timing cover is bolted to the engine block and the bolts tightened to a specified torque.

Possible cause is a leaking head gasket or timing chain gasket if the water pump mounts to the timing chain like on a ford 302 cid You probably are leaking into the crankcase through the headgasket. There is a slight possibility that the block is cracked.
