Off the subject, one thing we did notice, Mr Hagg was over at the house, was the difference in the new pistons Cummins is supplying. They have changed the bowls in the tops of the pistons, which is changing compression ratios. Bowls are shallower, and piston ring placement has been lowered. If I remember the conversation correctly, the compression is going up on the lower HP motors, shallower bowls, and down on the high HP motors, deeper cut bowls. But, we then have these anti-carbon rings, which throws another variable into the equation, as those sit taller than the liners. Rawze was talking with Mr Hagg about this, and that they will have to start compensating for this on the programming. And I would assume this would be done at the time of an in frame, as there are no notices as of yet from Cummins on these significant changes.

Another off topic thing I saw, or should I say an owner that I met up at Mr Hagg's shop, had an oil pressure issue. CM-871 motor I believe, still had the mandate. He was back to Mr Haggs for the second time with the same issue, a sudden drop in oil pressure in his low mileage Freightliner. Turns out the mandate was the issue, so much carbon had built up internally, that it was busting lose and clogging his oil filter. I guess he did not want to hear that on his first visit and refused the fix. The second time was the charm. You can lead a horse to water...

The oil filter that was removed off of this man's truck had collapsed from the build up of the carbon and soot. He had just had the oil changed... They fixed the mandate issue, changed his oil and filter, and hopefully this owner will take the time and spend the money to change a few filters and his oil in the next few thousand miles to flush his system of the soot and carbon. It was really bad, I am surprised he did not blow the motor after speaking with him.

If you still have the mandate, after what I have seen down here in GA, is that you should not even think twice about removing it from your motor. The carnage I have seen in Mr Hagg's shop is quite surreal. Just saying.

Waterloo, can he deman a DD13 Detroit? Gotta get something done soon. I'm over 75% on the filters now?
