Thanks for your response Jake. I hope your apprenticeship goes well. Not that many people getting into this trade anymore. I've had my license for 37 years now, both 310S and 310T. I worked in dealerships for a number of years, and it got to the point where I couldn't make a decent living fixing cars anymore. I went to a transit company about 3 years ago, and I'm fixing buses now. Probably the best career move I've ever made.
Sounds like you've covered most of the bases with your car. Not trying to be skeptical here, but are you sure that there's absolutely no degradation in any of the suspension bushings? If they're original, they're close to 35 years old now. Those bushings were never really designed to last this long, and if the car has been oil sprayed as regularly as you mention, the oil could start to cause the rubber in those bushings to degrade. Combine that with the age of the bushings, and it can cause problems. As for suspension parts, your best bet is to stick to a name brand (i.e. Moog), as others have pointed out. Most reputable auto supply stores (Carquest, NAPA, PartSource) should be able to help you. If you need to have control arm bushings replaced, you're going to have to do a bit of shopping around, to find a place with the proper equipment (a press), and some experience for a job like that.
If you're sure that the ticking noise has nothing to do with the exhaust system, then you're probably looking at an issue with the valvetrain. Are the valves adjusted correctly? What kind of camshaft is in the engine? Do you know if there are any special valve adjustment procedures for the camshaft or lifters? Is the oil pressure OK? Once again, I'm just thinking out loud here. Hope it helps.
