Lost power steering and had to grab a handful of wheel to not hit a light pole. About 5 miles later while taking a turn the truck died. Come join the discussion about modifications, towing, classifieds, troubleshooting, maintenance, and more! NOx emissions were reduced by at least 63 percent compared to the 2010 LMM according to GM. Much beyond that, its our opinion that both the stock pistons and factory rods are on borrowed time. Whats the easiest way to diagnose a cp4 that shit the bed? I may be able to register the truck in Utah if push comes to shove. That shit the bed warranty policies and more squirts out the injection (. Took to dealer and they replaced two sections of fuel line that looked a little kinked and thought fixed it. Im Having same issues. That, regeneration intervals are less frequent with the longest production run date. The electrical gremlins have taken over! The LBZ injector nozzle has seven holes for fuel to spray out of, but the LMM has six which means there are two opposed streams of fuel directly above the wrist pin area of the piston, which causes hot spots directly on top of the weakest area which can lead to cracking. Openpyxl Load_workbook Keep Formatting, ive had the following repairs done in the last 6 months: fuel injectors twice, fuel rail, high pressure fuel pump, every sensor in the truck related to emissions. The electrical gremlins have taken over! I reset disconnecting batteries each time but same problem. In addition, there were some noticeable improvements in the form of a stronger motor and a fuel system upgrade. Redesigned pistons, and a stronger block GM decided to go from (! When driving Ive noticed that if your in a higher gear and are in a since lugging it, when I give more fuel sometimes it cuts out out and comes right back. I have a 2001 6.6,,engine will turn over but will not start without a little starting fluid.Then it will run fine. On paper, higher fuel pressure sounds good, but you cant talk about common LML problems without mentioning the ticking time bomb of an injection pump. So what improvements were made to glean nearly 400hp and 765 lb-ft of torque out of the Duramax? The pistons in the LBZ and LMM are very similar, but casual observation would point out the LMM pistons break a little easier, but its not due to the emissions system, rather the injectors. Power is reduced for about 100 feet or so then it takes off and runs fine. the truck seems to be regenerating all the time ie it smells like def fluid all the time, rather than just now and again. The introduction of common rail injection powered by the Bosch CP3 injection pump made the LB7 Duramax stand apart from other diesels of the day with excellent power and efficiency. Fortunately, it is not a costly repair, somewhere in the neighborhood of $400 to $500. 24 miles later same thing. The LML Duramax improved upon what was already regarded by many as a stout motor.
