Toyota Repair: Oil in spark plug tube 92 Camry 2.2L, valve cover gasket, autoparts store

Question
I recently acquired a '92 Camry LE with the 2.2L 4 cyl. engine with 92K on the odometer.  When changing the spark plugs and removing the #2 plug from the spark plug tube it came out covered in engine oil.  It doesn't seem to be burning any oil so I think the oil is leaking into the tube from the head.  Is there any way to fix this without replacing the entire head?

Answer
The spark plug tubes are removeable and can be resealed.
Remove the valve cover, remove the large 32mm nuts on top of the tubes you can then get the valve cover off.
The tubes thread into the head and can be removed with either an internal or external pipe wrench, once the tubes have been removed clean the threads on the tubes and in the head, get some silicon RTV sealer from the local autoparts store, make sure it is for high temp applications and apply to the threads that go into the head, reinstall them, put on a new valve cover gasket and you have fixed the oil leak.
