is that vis 5.6 @ 100C thats what ate your pistons but at 40K it was fine, did you find out what happened.

"Maybe he would have never knew he had a problem if he changed the oil every 3000 miles."
One might have detected diesel when checking the oil, which hopefully is done at more than 3000 mile intervals. But as peviously mentioned, with fuel in the oil it doesn't matter what oil of filters or change interval was used.

I was doing fine until I decided to warm up my diesel chasing a import. . .

The failure occurred during the last 7k miles...there is no question that the fuel dilution was NASTY! No oil would have held up to that amount of fuel. It's a tough break for sure. As for the comment about UOA's being run to failure mechanisms I'd have to politely disagree. UOA is a conditional maintenance tool that is detection based to help ensure continued reliability. If you use UOA for trend analysis and change out the oil prior to "failure" then you have done it right. Now if you push the limits every time to where acidic corrosion and abrasive soot become a reality then yeah you are running to failure...that option definitely does get expensive.
Hi,
in another Thread the visual appearance of a lubricant via the dipstick was questioned
My reply was that the visual appearance of a lubricant can tell much when used as a blotter test. The rising lubricant was your "indicator" and a blotter test would have picked up the fuel dilution - confirming it
On some diesel engine families internal fuel channel/line leakages can cause lubricant dilution issues - it's not only caused by leaking injectors
Sad it turned out this way - as Bruce indicated fuel dilution (from?) was the cause of your engine failure

were the top rings broken? since they are not in picture would broken rings be a detonation or fuel metering problem? that would be the cause the broken rings the result and high fuel in oil.

the grooves cut into the cylinder is how the fuel got into the oil.
the grooves were put in there with my heavy foot and my 7.3 that was apart who knows how many times before I took it apart.
the root cause was turboed non turbo 7.3 with 6.9 heads I put on that I had to shave .007 to get straight, soooo that means it lasted 120,000 miles too many.
a little less compression would of helped me...

Hi the rings were good no breaks except for the oil ring stuck to the piston, as you can see.
my engine ran fine before I yanked it. I went from 20mpg to 17 and that was enough for me to park it and figure out what was next on the list
