The guy ran straight water in the engine (and the cooling passages show it). None of the other bearings show anything similar. The head gaskets looked okay, but I don't think the guy torqued the heads down properly as it was easy to remove 1/2 the bolts and I practically had to stand on a 5' cheater pipe to get the rest off (impact gun didn't even make a dent at 90psi).
