TB42S Rear Main Seal

Hi All,

Have the motor out of the car, rear seal is not leaking but thinking while it is out I should change the seal. Am I potentially creating an issue with the seal by attempting to change it even though it is fine at the moment or am I better to change it while I can. Appreciate your thoughts.

Get a good seal, not a cheapy. I usually change any welsh plugs on the rear off the engine as well, especially if they're steel ones.
