[DeTomaso] BBORR engine failure clues

[John Taphorn]

Michael

I believe that you stated you were running a solid roller lifter cam.  The 
excess lash occurs as the needle bearings in the roller's wheels turn to 
dust.  The base of the roller then rides on the cam lobe and the wear 
rapidly against one another.

Welcome to solid roller hell from one who has made the journey.
