In the data I'm collecting (for a thread to be), I've found (so far from photos of oil reports & bearings).
19 oil reports did find bearing problems & it was confirmed.
3 oil reports said that they were ok, and although they hadn't gone through to the copper their was excessive wear in the lead layer for their mileage.
2 oil reports said ok, but their was major wear to the lead & slight/small amounts of copper showing.
4 Oil reports said ok, but pb & Cu levels elevated + shells heavily worn or failed (1 owner).
3 oil reports said ok, but with 2 of them, 1k & 1.5k miles later the bearings were pulled & at least 1 bearing was mostly down to copper! And the 3rd his engine blew up 1k after the report from a spun rod bearing!
Here's the info/links I've got for those last 3:-
Confirmed analysis missed bad bearings
delirium330 - https://www.m3post.com/forums/showthread.php?t=1300528 - Cu/Pb at 1 & 2, yet 1 bearing to copper!! Oil life 3092 miles. Bearings changed just ~1500 miles after report.
IIAp3x - https://www.m3post.com/forums/showpo...3&postcount=11 (no photos, but states that engine blew up 1k after report!). Pb/Cu 12/2 ppm. His extensive thread - https://www.m3post.com/forums/showthread.php?t=1119912
sv848evo - https://www.m3post.com/forums/showpo...&postcount=736 - unknown mileage on oil, but more than 2800 miles. 1 bearing mostly worn through to copper! And a few others just gone through to copper. Oil report, pb 7ppm, Cu 3ppm, bearings changed 1k miles later.
I'll post links to the rest when I post my thread about it. |
Thank you for this. If this doesn't prove that a Blackstone is worthless, I don't know what does.
