I had the misfortune, a year ago, to have my 2.8SS rip a piston in half on the chassis dyno. The motor had less than one hour on it. I finally got it completely torn down. The Glyco main bearings, which were coated by Calico, looked fine.
The rod bearings did not.
Of course, the wear pattern on the rod on the blown up hole looked uneven, and the Pauter rod was a bit twisted (but they sell singletons). But no such abnormal forces affected these bearings, and all five sets look like this. I am pretty sure, from memory and from examining where the two bearing shells abut (which seems to be where no wear at all usually occurs), they look to have had the same coating as the mains, though now basically gone.
I think someone, within the last year or so, sent in a photo of a similar mottled wear pattern. And from an engine prematurely torn down for some other reason? I don't know just what to make of it, especially since they were coated, but most of that is gone. Crank looks fine.
Because this is the 66mm crank (2.0-2.2), there is no option to use GT3 rod bearings. Leaving me wondering what to do for replacements. The plain old Glyco intermediate shaft bearings look just fine, as one would expect for less than an hours use. But these don't.
