If that doesn't fix the problem then it's going to take more invasive work to solve it and depending on how much you love the car and/or want that noise to stop it may or may not be worth the time and expense to solve it. As long as you keep it filled with oil and it has good oil pressure (which I would definitely check with a mechanical gauge as the stock gauges are notoriously poor indicators of actual pressure) then the ticking will not actually harm anything. You should run an oil pressure test just for peice of mind - it should be no lower than 15 to 20 psi at idle after the engine reaches operating temp, and it should rise to 40 or 50 psi at about 3000 RPM. If it does not you may need to replace or reseal the oil pump and at that time it would likely be a good idea to replace the cam tower o-rings as well.

you meant to say 1988 right, not 1998?
lots of ticking information on here, it's very common and we're very familiar with it. don't bother checking oil pressure, that's not likely to be your issue. it's one of two things causing it probably. either the oil pump needs resealed to prevent air bubbles getting into the oil supply (the suction side of the oil pump block gasket gets sucked in), or the actual HLA's are dirty and sticking. the risolone/atf adding only works if it's the HLA's being dirty.
though in some cases the oil pump can't properly seal even with a new gasket and the oil pump itself just needs replaced so the gaskets will seal properly.
change your oil often on these things, the HLA's can not tolerate dirty oil well. the good thing is there's no valves to adjust, the bad is they can't tolerate poor oil change maintenance.
