Quote »Bunta: You name it, I've done it. (Well not really, just seems like it.) I've done the timing guides & tensioner, clutch, brake pads and rotors (not calipers yet), fuel pump, water pump, fuel injectors, muffler, belts, even the spark plugs. The tapping sound I'm guessing is due to low oil pressure, I'm gonna pull and check the pump and replace the gaskets, it just sucks to do it in the school parking lot. Also, the exhaust is white no matter the temp of the car, but I don't think it's the head gasket. (praying it's not)[/quote]
What's the mileage on your 89?
Some of the stuff you mentioned is stuff that needs to be replaced as far as routine maintenance goes. Such as the belts, rotors, pads, clutch (for the mileage you have it was needed) etc etc. I feel your pain though...
It's one of the drawbacks about having an older car, but as long as you replace with high quality parts it's not a problem. It sounds as though you do your own work, which makes it relatively less pricey. Nissan parts aren't cheap but it pays you back in driving enjoyment!So i plan to keep my car indefinitely.

(of course having another car as a daily driver in the future)
