It's actually harder than a v8, but still very doable if you are careful and pay attention to what you're doing. First things first you need to get a Chilton or Haynes manual. You'll basically have to take the entire top end of the motor apart, including manifolds, alternator, ac pump, water pump, radiator, etc to get to the timing belt. One of the hardest things I remember was the crankshaft pulley belt - a royal PIA. Ended up hitting it with the propane torch and a cheater to get it. Reassembly is pretty easy, just keep everything clean, follow your manual, and pay attention to torque specs. Any questions let me know. I know I had about 1000 when I did mine, but it's all worth it when you fire her up for the first time.
