Here's my first UOA after a rebuild. It failed California smog because of visible smoke, the oil control rings wore out. On tear down everything else look good but I put in new parts because I purchased a rebuild kit that included pistons, bearings, seals and gaskets. I also had a valve job done and no valves needed to be replaced. This car is a 30 year daily driver and has never let me down except once for a dead batter a few weeks ago. Most people look at the carb and all those vacuum lines and warn me about problems. There has never been a problem or even a hing of a problem. The system works well and has never given me any trouble. I have no plans on ever selling the car and I hope it last long enough for me to drive it to my own funeral.
Blackstone misread my notes. It wasn't 480K miles but, 420K. And the engine is an EW1, 1500cc carb 3 valve engine, not a 2.4 FI 4 valve engine engine.
I gave up on uploading the pdf file and converted it to text, instead. I hope it's not too confusing to those familiar with Blackstone reports.

ADDITIONAL INFO:
COMMENTSLARRY: Wow, you had 480,000 miles on the last engine?
That's impressive! What's your secret? It lookslike your new rebuild
is off to a good start as far as oil analysis is concerned. Universal
averages showtypical wear for this engine after about 6,800 miles on the oil.
Your run was a bit shorter, which is finebecause all metals read on the low
side of the average range, showing some really nice wear trends goinghere.
The viscosity was a little low, but that shouldn't give you any trouble.
The TBN was fine at 7.2. Bringon the next 480,000 miles!
