I have a Cm2350 with 560k miles oil pressure is at 42ish cold start. But once truck fully warms up it idles like at 19psi. At 1500 rpm it’s at 38ish. Is this normal? What should I check for?

sounds fine to me.

What is your oil change interval and what is your typical fuel mileage?

When is the last time you did 3 oil changes at short intervals (like 3,000 miles apart) to rid the engine of built up soot levels?

has the fuel pump guts been replaced?

I was at Mr. hags yesterday .... this is 2019 ..... You would think that there would be no engines left with ceramic plungers in them....

He found a 2015 CM2350 with ceremic plungers in its fuel pump. - There is a factory invoice where the "ROLLERS" were changed and updated recently by the stealershit!... YET they left the ceramic plungers of instant engine death in the pump when they did the update.

Shows how stupid they really are and how little they care about someone's engine of livelyhood.

I change oil at 10k intervals and average fuel MPG is 5.5. I have never done short interval oil changes. This truck is demandated.

With it de-mandated the oil should not be getting very sooty.

10k intervals is about right for a truck that only gets 5 mpg or so. However, I have no idea how people make money in trucking with such s#hitty fuel mileage!... more than 70% of your profits are going straight to an already rich oil company -- your doing nothing but giving away money.

if the truck is demandated, then I hope like hell you learned your last lession (mentioned {Here} ) and used one of the top people recomended to inspect and/or make the program.

The oil at 10k looks decent. Doesn’t look sooty. As far as the file, I ended up getting new files for all my trucks from a guy that has good reputation doing deletes. All my trucks ran way better after the delete file. The truck gets 5.5mpg at 80k lbs in the Southwest where there is hills pretty much every direction. Ive had about 15 trucks over 20 years and best MPG I can get is 6.8 out of cm871 and 6.5 of a cat c15 Acert.

You have a bad delete, I would bet on it. "Some guy with a good reputation" has ruined a lot of engines. We see it here literally every week.

A guy with a good reputation did this engine. Timing too high. Vg closed too far to compensate for not removing the scr.
