My first rebuild in 01' I thought I blew piston but it turned out I starved the motor of oil and I spun a bearing. I got a new crank and did a full perf. rebuild. I have the autometer ultralite elect. gauge right next to my steering wheel. You can get them from jegs. Very handy tool to have and one of the many "necesary" gauges to have and on the list for anyone doing performance mods, especially turbo! I know you don't have theat yet, but I'sure your thinking about it.
