The reason for the rebuild... well... some people are going to balk at this.
I bought some nice shiny parts - JE Pistons, in particular, but there were a few more. When I started the new job, I stopped driving to and from work... and with the missus away most of the summer (she spent most of it with her folks, on pregnancy leave) I had access to our other family vehicle.
When I realized that I had started up the car ONCE in three months, I figured I might as well use the downtime. So, in august I tore it down to put in all the new bits.
Realistically, I could have waited... but hey, I had spare time and wanted to wrench.
