If you replace the valve cover gasket and change your spark plugs it will go away... make sure to use silicone on the gasket as well if you want the fix to last. I've replaced the gasket on my car twice in the past year... and i'm sure it will come back again eventually... But it's just a valve tap... if it's annoying enough... theres your fix.

your best bet is exactly what pswirley said...

Also, I'm not sure if its a great idea to put synthetic oil in that car unless it has already been switched over. Leaks all over the place aren't so fun. And I wouldn't add an extra qt. over whats recommended. The car will just quickly burn it off. An oil additive such as lucas oil stabilizer MIGHT help a little bit.
The real problem is the ol' m20 engine just needs a little valve adjustment. Do one every oil change and you'll be good.
