RE: OS 91 VRDF experts wanted
lfinney....not good news, but thanks for the info.
It sounds like the rear bearing just doesn't have the size needed to put up with the forces applied. The best remedy besides running the highest quality bearing would be to remove as much dead weight from the piston as possible and to use the highest oil content the engine is happy to run..
I would consider this engine a great candidate for one of my full complement bearings.
