Besisdes the overall visual, what are tests that can be performed on an assembled 13TT when it is NOT in the car?

i.e. look for rust in the coolant
test the oil (sniff test or lab analysis?)

Any suggestions would be appreciatied,

garfinkle told me to look into the exhaust ports and push on the apex seals to see if they are stuck or broken rotate the crank slowly do not pinch a finger as I did .This saved me from buying a bad motor at the junk yard .I saw the bad seal with a flashlight. thanks to the gar

Take oil pan off, make sure housings are not blackened, as this is a sign of the motor being overheated. You can actually perform a "poor-man's" compression test on the motor to make sure all seals are in proper working order and that all faces of the rotors are holding compression. Rotate the motor via breaker bar, or the like, attached to the eccentric shaft, and make 3 full turns with it. Every half a turn (top and bottom) stop. You should here a "chug" of the motor releasing compression. If you don't hear 6 "chugs" of the motor (2 rotor), you don't have compression on all faces of the rotors. Hence, the motor needs to be gone through. Like the other guy stated, you can use a flashlight and look in the housings to see if you can visually inspect any damage.
