I was recently driving home last week and I accquired this evil knock from 
the engine.   I have since removed the oil pan and valve cover checkin what I 
could for loosness and clearing.  Everything seems intact and no visual 
problems.   Yet when under a load the knock appears.  Anything over 30 and 
you can hear it very prominently.    I am hoping I wont have to remove the 
engine again but its looking that way.    Any suggestions or remarks to what 
it may be that I should check befor I really start to take things apart would 
be greatly appreciated.
