My spare motor is supposedly a rebuilt 2019 R motor. The number ID tag has been popped off it which is typical of motor rebuilders, it has the smaller R turbo but has the larger RR injectors. Both map sensors are off it also.
I have a depth gauge that I can put down in the spark plug hole and check for piston height, but is there a simpler way to determine which motor this is?
