Jake and Charles, somehow we knew that we would get back to this subject. We never expected it would be so quick

Our customer has installed LN bearing "upgrade" along with AOS and a new clutch, cost $4000. 2 years and nearly 30,000 miles later he found metal shavings in his oil filter and on his magnetic plug. He sent his engine to our shop for core credit after he purchased one of our 3.6l rebuilt motors. He's out total of $16,000 because of his "upgrade", and now regrets he ever touched the original bearing in the first place.
Luckily, he caught it in the beginning stage, bearing is loose, but no major engine damage yet. Metal shavings from inner and outer races were circulating inside his motor and managed to wear out main and rod bearings, we also found tiny shavings from the bearings in oil.
Here are links to 3 videos, 1 shows bearing still in his motor, 2- when it's being removed, and last one once it's out.
If anyone else doubts which bearing is better, now you know. This is the exact reason why we use only roller bearings in our rebuilt motors. We have customers who have been driving their cars with our bearings for years, and they have no problems. They are far more durable, and have 5x more load capacity than ball bearings, even with ceramic balls. Every time we try to speak about it publicly, we get shut down. Maybe now people will see for themselves. Everyone deserves to know how much it costs to have LN bearing failure.
Please do not take this as provocation on our end, we did not expect this to happen. Our customer will be happy to confirm this in case anyone will question our post. Please take this as a warning, and hopefully a lesson.
