VR1 20-50 in a small block chevy used at the track in 20-40 minute sessions over a weekend. Oil looked like gold paint when I drained it so I sent it in for testing.
This sample came out of the oil filter, I cut it open with tin snips.
Scariest looking oil analysis I've ever seen. I was expecting to see widespread bearing damage, but was the wiped rod bearing the only one you found?
The numbers in the UOA probably are exaggerated because it was taken from the filter.
With the aluminum and tin in the sample, it may indicate cam bearing distress. How do those look?
Yeah, when I saw those numbers expected to find catastrophic damage to the engine.
I plan to pull it over Christmas shut down and get a better evaluation done.
The plan is a full rebuild regardless.
