HAHA, good question. I just recently replaced the sparkplugs, added new ignition wires, and had to put on a new valve cover gasket.
Yeah, its a pain. whoever designed the NA supra engine bay layout was nuts! If you want to replace sparkplugs you have to take off the intake manifold, which now makes the small 10 min job of spark pulg replacement an hour and a half. Its pretty tricky. Just search the net for diagrams if you really want to try it yourself. I suggest goin to a shop that know what they are doin. Good luck
