Well, as committed... the good, bad, this is the ugly. I took the car out Mon. evening ...simple cruise...think I hit 1 psi. After driving ~ 5 mi I stopped for gas. After filling up she wouldn't start. Multiple attempts...cranked strong, but would not start. Thought to let the engine cool. After some time while waiting I looked underneath and saw a pool of coolant generally...under manifold area (recall I still have the ex mani leak). So, popped the coolant cap and was topping it up. As I continued to periodically crank the engine I could see wafs of smoke emanating from the coolant overfill bottle coinciding w/ when the engine was being cranked. After ~an hr of cranking, waiting, and getting jumps...finally got her started... white smoke billowing everywhere, and was able to drive directly home. Since...she starts, but has rough idle and fair amount of white smoke. So, I'm reasonably confident, unfortunately, that whatever happened last Sat ruptured the coolant o-ring in the rotor 2 housing. :sad: I was logging last Sat when the initial "event" happened and AFRs repeatedly drove to ~10.6 in boost, coolant and oil temps were ~205F and 190F, respectively. After the event coolant climbed past my alarm threshold (215F) to 220F before dropping back to normal range. So, given that data my presumption is this was simply the product of boosting a 65k mile reman'd non-built engine, which btw I expected to "go"..., but not so soon.

So, currently considering options, cost, and time frames for next steps...
