1975 Ford F-150 - checked the spark plugs and noticed oil on the threads. Does anybody know what this could be? Head gasket, or some other valve gaskets or something? Haven't checked any of that, just noticed oil on them when pulling and checking everything out.
Any input is greatly appreciated.

probably valve cover gaskets. Those plug wells can hold some oil easily. Hit it with some degreaser and a pressure washer. Make sure you put plastic over the distributor and carb so you don't do any damage though. Clean it up nice and it will be easy to see the leaks. Buy the rubber FelPro gaskets. The cork ones just don't last and its worth the few extra bucks to not have to deal with it anymore. Post back with any more problems
