Exploder coming together
All the pieces are in place, I have to install the last four plugs, add coolant, and back it out to the driveway and fire.
Which, of course, means that we have just received 2 inches of snow.
Why not? I mean, sheesh. What fun would it be working outside on a dry driveway.

Good news indeed! Did you ever discover what was causing the exhaust manifold to overheat?
