Hey Doc! I remember you saying something about
concentricity between the crank and the rear main
seal, and that sometimes its way off. Also, that
sometimes you're better off using a rope seal
because of this.

What is a good way for checking this, so that
you use the best seal (rubber or rope) for your
motor? (note: my motor is still in the car, if
this matters).

Thanks
Mike

This is hard to check with the engine assembled and in the car, I check the main seal receiver groove and cap position as part of engine "blueprinting" before the engine is assembled.

For an "in car" re-seal, I would go with the rubber type seal. They are easer to install and more forgiving for your in car reseal job.
