It sounds like you may have an engine problem causing the oily plug condition. A compression test and leakdown test will determine that. You may have a ring problem or a valve seal problem. Changing the gap willl not help with this. Sometimes running a plug with a higher heat range can help with minor fouling. You want to determine the underlying problem that is causing this first. Good luck.

Example: For my 86E the stock plug is AC Delco R43TS. The R45TS is a hotter plug. Your 84 uses the AC Delco R45TS stock. Not sure what # you would need to be hotter, but I would just stick with the stock ones and fix the problem and not bandaid it.
I believe you would use the same gap as me...035. I would also stick with that.
As stated above, do a cylinder compression test...adding oil in the cylinder on the second test. Do a search on the net for the proper procedure.

you can buy non foulers you screw on the end of spark plugs and then screw into head. gas milage suffers a little, but it keeps your car running until convenient to fix. i have used them in past and they do work.

any parts store in your area should sell them. ask for spark plug non foulers. if they dont know what you are talking about, explain it to them. a hotter spark plug wont help much, so dont let them talk you into a set. non foulers are sold individually, so just buy as many as you need.

I would try Autolite plugs, normal range, .035 gap. Back in the old days, my big block Chev(way too much cam) would gas foul any other plugs in a few weeks of street driving. An old drag racer told me to try Autolites( I know, Ford plugs), but they did the trick. Might work until you can fix the problem.
