I did replace the HP fuel pump head as a check valve failed. Truck also seems to have leaky injector(s), rail psi bleeds immediately on shutdown. I retorqued the fuel lines and tubes to no change.
Truck is also burning a TON of fuel if having to idle overnight. Like a noticeable amount on the gauge. Will also be able to manual regen in the morning from the switch. Turbo is also starting to hang up randomly. What a money pit. If it was mine it would be converted to ahem “less hassle”, but I guess that isn’t a option since I go to California regularly.
Lots of issues. Still runs fairly well. But with just shy of 600k miles go figure.

just an fyi: not encouraging it, but if the de-mandate you talk about is done correctly, the thing would pass those Cali inspections and sniff tests. There are plenty of of ppl here that visit the communist state and even have stickers where they get tested and all that stuff is hollow. Alternatively, the thing can be made much more lenient without removing anything via some custom programming to make it a lot less of a sensitive headache even if someone did want to leave it all in tack.

Everything your describe screams a lifetime of neglect and also highly likely the thing has been driven its whole life mostly below 1500 rpm (considered abuse) . - Sad indeed. Cannot blame the engine on that but instead a lack of education towards proper care and maintenance. Repair shops any more will not help you actually "maintain" a truck these days, nor will they do anything preventative. Our industry has changed into this deranged mentality of "Drive it till it breaks, put out the fire using the least amount of effort, rinse and repeat." That and this stupid narrative used by the mega-fleets of jacking up rear axle ratios, starving the engine of useful power, resulting in increasing fuel mileage (due to starving the engine of actual power and excessive lugging) thru false means, lugging a diesel engine to death, cutting its lifespan severely.

... all the while, everyone wondering why they have noting but repeating and major problems as soon as the truck gets a bit of age on it. It becomes completely left to the truck owner and/or driver for avoiding all that stuff and therefore 85% of why O/O's and small fleets chase their tails, fighting all the problems and premature engine failures more than they make decent money. That or they resort to perpetually leasing newer equipment where a huge chunk of profits do noting but make truck payments to already rich, greedy OE dealers$its.


600k miles on a lugged to death + neglected engine = an engine at the end of its life already.
