[Fot] Dreaded Thrust Washers in the Oil Pan

[Charly Mitchel]

Hey, a better fix is to have the cap machined to accept another thrust 
washer on the flywheel side.  Then have the thrust washer pinned to the cap. 
This doubles the surface area and is very effective.  I've done this to my 
race motor and have virtually no wear to the thrust washers.
