So, Thursday engine 2 was back together and the gas skid was "mostly" working. Ran E2 most of the day, as we screwed around with programming the PLC on the gas skid.
1:30AM Thursday Night/Friday morning E2 dropped a valve.

The piston was beat to crap!
Fortunately, we stock all of the parts and had the crew onsite for the top end cleaning. E2 was back on-line around 1PM.
E1 was nearly complete on Thursday and was on-line before 9AM.
