Here is one I haven't heard of before...sorry for the long story:

On my Supercharged Car the tuning took a dump on me and I backfired through 
the motor  which hair-line cracked two pistons (5 & 6.)

I replaced the pistons with two from a parts motor.   Present rodbearings 
looked good and installed/torqued them to spec.   Buttoned her all up.

Fired her up and got a rod bearing knock (insert cuss words.)

I eased her 10 miles over to Texan Tony's house.    Pulled the two rod 
bearings out and they were almost melted/very coppered.   Luckily the crank 
was not scored.  Pulled no. 2 bearing out and it was fine.

Tony put in brand new rod bearings on the pistons/assembly lubed etc.  
Buttoned her up to spec and same rod bearing knock again.

?????????????????????????????

Thanks mucho,
Murph
