I agree, pull the motor.
I bought a 92 Stealth TT at an auction that smoked so bad you saw nothing behind the car. A police officer actually followed me for 5 miles on the way home and didn't stop me.

The first thing I did was check the plugs and do a compression check. All cylinders were 155 except #2 which was 30.

Number 2 spark plug looked exactly like yours and the two middle ring lands on the piston were destroyed, plus the cylinder is screwed up.

On this car the kid didn't monitor knock or anything else but installed a MBC and wired the wastegates shut. The two middle main bearings were down to the copper also.

You a have a really nice car, fix it right with forged pistons and don't get cheap on any internal parts.

Good luck
