As for the pump, that can simply be a separate thing but coincidentally happen at the same time. Maybe just a bad wire (hard fit when wiggling the cover over the big fuse box.)

I was thinking a minor head lift could be possible. However, I doubt it as I'm on spring pressure at like 7.5 lbs. I plan to drain the oil and see if it comes out milky to confirm that the coolant and oil are not mixing.

Off to dream land I go. Guys /gals, keep brainstormin for ideas while I'm snoozing.

I agree with the low battery issue. The puff of black smoke is from the injectors firing during the starter slowly cranking the engine. When it starts you have all that unburnt fuel pushing through your exhaust. Good luck!
