[Fot] Thrust washers

[Greg - Lunker Hilyer]

Hello all,
Tear-down of my race motor revealed a peculiar failure... top half of  
the front thrust washer badly hammered. Other 3 halves OK with only  
normal/minimal wear. Thrust area of crank looks OK.  I suspect "junk  
part syndrome" but am interested in any other explanations.
While I'm at it, I'll also solicit recommendations on QUALITY  
replacement parts:
Thrust washers
Crank & rod bearings
Timing chain

Thanks in advance,
