It's a non-interference motor. Many many many people have verified this when tearing down their engine. Inspect everything you can think of, and swap out every fluid you can think of (don't forget the often neglected break, coolant, diff / trans / t-case fluids etc). Inspect anything that looks rubber. A lot of people are quick to replace things without inspecting them... I'm not. I'll check out the plugs, wires, cap etc. If they look questionable at all, I swap 'em out. If not, I clean 'em up and move on with my life.
