[AT] Bad valve on an M- Update

[Wayne Snelling]

Dick: First impression is that the top end is not oiling and you may 
have some bad rocker arms/pushrods. That silver gray dust should not be 
there and it sounds like metal to metal results. Have you run it with 
the valve cover off to see if any oil is getting to the top. You may be 
lucky or unlucky depending on which way you think, but find the reason 
no oil in top-does the engine have good oil pressure?  New 
rockers/p-rods are cheaper than overhauls.
