Totally Dead #1 Rotor
Received a call from a local auto shop specializing in foreign cars. The owner was doing a freebie checkup for a friend's single turbo FD which was having idle problems; idling very rough. He was unsure of the problem.
I grabbed my laptop, digital compressor tester, DL, spare plugs, and some tools and went over to the shop. The problem was the front rotor had "NO COMPRESSION". I tested it two times and it logged 0psi. I then logged the #2 rotor and it had 115 PSI. Went back to the front and 0 again. I even logged me blowing on the pressure sensor and it recorded above 0 psi. (yea make a joke!). Then I used a mechanical gauge and it also read 0 on #1 rotor.
Afterwords with the plugs cleaned and put back in, the car started up without any problems but was only running on #2 rotor.
This was the first time I seen such a total failure of a rotor.

I've torn down a motor that had severe carbon inside and all six apex seals were basically gone (out the exhaust). It spun over very quickly because it was making zero compression on both rotors.
