Though the LMLs cast-aluminum pistons are similar to what is found in the LBZ and LMM engines, the versions used in the LML are void of wrist pin bushings (a major weak point in LBZ/LMM pistons) and the wrist pins themselves feature modified ends for improved piston support. I am guessing it's related. By injecting diesel exhaust fluid (DEF), a mixture consisting of 32.5-percent urea and 67.5-percent water, after the DOC (yet before the DPF) during the regeneration cycle, harmful hydrocarbons (NOx) are converted into carbon dioxide, nitrogen and water.

A new front cover, drive gear, oil pickup, windage tray and upper and lower oil pan were required to accommodate the new pump. On the LML, a ninth fuel injector is located in front of the diesel oxidation catalyst (DOC) in the turbo downpipe. The larger pump flows 11-percent more volume than the version used on 01-10 mills (the LB7, LLY, LBZ and LMM). You check the desired rail pressure with the LML Duramax had a block! What this meant was the LML Duramax had a stronger (and lighter) rotating assembly. Failure of this CP4 pump is usually catastrophic, causing instant contamination of the entire fuel system with metal particulates. Of course, it doesnt help that diesel fuel is prone to absorbing water and contaminants. Going to start walking home. About 5 miles later while taking a turn the truck died. By installing a lift pump with extra filtration from FASS or Airdog you will extend the life of the injection pump and injectors by allowing only the purest fuel into the system, and by feeding a steady supply of low-pressure fuel into the injection pump, it can better focus on its main task of generating high-pressure fuel. The 2011-2016 Duramax suffers from a high pressure fuel pump issue unique to this year range. We know it sounds confusing but dont worry well cover it below and with that said, here are some of the major changes that came with the LML Duramax.

For all the dirt and sunshine on the Duramax with the longest production run to date, keep reading. If you live in a warmer area where freezing temperatures are not an issue, you can largely ignore this problem. When cranking the injection pressure still shoes zero. A selective catalytic reduction (SCR) system joined forces with the rest of the emissions system to better help curve NOx, while a ninth injector was added to eliminate the oil dilution problems associated with the soot-burning, regeneration process on the outgoing LMM engine. It is deleted and has a bully dog programmer. The emissions-aftertreatment system uses urea-based Diesel Exhaust Fluid (DEF), injected directly into the downstream exhaust (behind the turbo) by a simple ninth injector that feeds raw fuel and DEF, which helps ignite and burn off trapped emissions particulates in the diesel particulate filter (DPF) during active regeneration. Then I noticed the when I was turning to the left on the freeway the noise goes away completely. That lasted about. Its clear that GM made an effort to get back to a lighter rotating assembly when it designed the LML. For a year now since 20000 mile mark I would be driving the truck either unhooked or pulling our living quarters horse trailer and for some reason it would just go into reduced power. The problem, which is exclusive to the 6.6L LML Duramax V-8, is a faulty fuel filter restriction sensor. 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. 177 sold.
