When they are as discolored as mine, I would certainly not reuse them. The discoloration indicates an extreme overheating of the material which has changed its metallurgic properties. A significant loss in strength of the rods is very likely.

This is how your conrods look like after spinning bearings: Notice that only three failed after oil loss, the other two were still in good condition

I have installed glyco sputter bearings twice (before and after the previously described oil incident) and still running them now with CX conrods, never have had any problems with them.

Couldn't it be a blocked oil supply of some kind that have caused this? Last year an oilhose of the oilcooler in the radiator came loose on the higway, pumped all oil out in no time. Egine jammed. When I dismanteld it, only three bigend bearings ware damaged and the thee conrods darkblue because of the heat. Ofcourse I had to replace the crankshaft too because of the damage at the bigendbearings, but the rest of the enige was undamaged... main bearings, camshafts, cilinderwalls,, pistons, pistonrings... all undamaged. Even the turbo showed no damage. Clearly the bigend bearings are the first to go while running out of oil, long before other components are being damaged. When clearences where to tight you would have felt that while rotating the crank by hand during installation, I guess.

Damn, bad luck!
