2006 Cat Eye Chevy Duramax – After weighing down the pros and cons of each Duramax, it’s time to pick a favorite—but it’s an easy choice. The fact is that each variant of the 6.6L V8 diesel engine has its strengths. The LB7 was the most basic in terms of fuel efficiency, but the LLY came with the largest turbocharger offered. The LBZ was equipped with many improvements, including more power, and the LMM is almost a mirror image except for its use of a diesel filter. The LML brought higher fuel efficiency, cleaner emissions and nearly 400hp into the lineup, while the current L5P upped the ante even further with 600rwhp capacity in ’17-new GM trucks.
To touch on what’s covered in our Duramax History Lesson series, let’s run over a few of the flaws associated with each reel. Then we reveal what we like best and why. While you may be biased towards another Duramax RPO code, we don’t blame you. Regardless of generation, you can’t go wrong with any version of this engine. The hard part is, it’s very stable. When properly maintained, they can easily give you 300,000 miles of use, but they can certainly go 500,000 miles (or more) if you’re willing to keep one that long. The Duramax platform has made GM a viable competitor in the diesel car game since the turn of the century and there is no indication that will change in the near future.

It doesn’t get much simpler than the previous 6.6L: the LB7. With the exception of the California models, the original Duramax was largely free of any engine control problems that would be introduced in the years to come. . No more exhaust gas recirculation (EGR) and certainly no diesel particulate filter (DPF), just a turbocharged version. The LB7 also used a geometry turbocharger—only the Duramax does it—which means no turbo vanes or compression problems.

Forging the common-rail injection path in the diesel truck segment hasn’t come without its implications for GM. Cracked and/or leaking injectors can fill the crankcase full of diesel fuel, producing heavy smoke out of the tailpipe and causing Engine damage if left unattended for long. Today, the LB7 injector issue has been resolved (thanks to improved design and materials), but if we were in the market for a Chevrolet or GMC HD before, we wouldn’t be interested in buying a mile. low. ’01-’04 models.
With a large factory Garrett GT3788VA turbocharger attached to it, the LLY (available on ‘04.5-‘05.5 trucks) is sure to make plenty of power. a Duramax manufactured between 2001 and 2016. Thanks to its 62.6mm inducer. compressor wheel and high turbine vane height (15mm) of any GT3788VA, enough intake and exhaust to support 530rwhp in 2500 and 3500 models Chevrolet Silverados and GMC Sierras. On top of that, the LLY-spec’d GT3788VA sports a 360-degree boost boost for longer turbo life.
Unfortunately for LLY, it’s notoriously hot on the heels of the draw. This is due to the combination of a straight turbo mouth, a small radiator and a dirt cooler that blocks the flow of air, which is not it is common to see the coolant temp crest 230 degrees when working on this engine. Over time, with most LLY trucks being used for most of their lives, buying a 200,000-mile model could mean you’re pulling heads for new gaskets later on. .
With a stronger block, meatier rods, higher-mounted hoods, a revised, higher-weight common-rail fork and 360hp straight out of the box, it’s hard not to Dislike the LBZ, available on GM trucks during the ’06-’07 model year. While working to meet many of the NOx and food safety regulations set to go into effect in 2007, GM made the necessary changes to ‘ 06 allows the LBZ to become the LMM (‘07.5-’10) with a few changes. . As a result, the LBZ is a LMM without the exhaust after-treatment (such as DPF, and the mileage-and-long-specific-kill) regeneration cycle).

There is no doubt that GM’s use of wrist pins (and a thin protective wrist pin, to boot) weakened the ability of the LBZ pistons to handle tire pressure (ie torque), but the quality the use is also suspect for some. this year. If you’re in the market for an LBZ, just know that the factory piston failure rate is higher as you approach 650rwhp. At the power level near the dealership, we liken the cracked pistons in the LBZ to the piston pin hitting the 5.9L Cummins. It can happen at any time unless you dig into the engine and remove the gap – but it probably won’t.
In order to stand up to 765 lb-ft of torque in stock, GM revised the power block of Duramax and LML, offered in GM HDs from ’11-’16. So, the box is now used as a base in many of the operating systems that are built in the market. In addition to that, it needs improved horsepower—and a fuel pump that flows 11-percent more than the ’01-’10 engines used in the LML. To free up more horsepower (it put out 397hp, buy), the LML also sports the lightest assembly of any Duramax.
For propulsion purposes, GM was forced to move away from the Bosch CP3 on the LML, which uses Bosch’s CP4.2 instead. Although the small pump is rated at 29,000 to 30,000 psi and is easy to install, it is prone to malfunctions whenever it is not. a lubrication is present or debris is present in the high pressure oil system. The pit-in-the-stomach double-whammy is that, when the twin-piston CP4.2 destroys itself, it is usually taken with the injectors. The first thing to do when picking up a used LML is to put the CP4.2 in relation to the CP3 (if possible) or install a lift pump (for installations with low oil supply).
No other Duramax in history has offered what the L5P does. The Bosch CP4.2 has been ditched for a Denso HP4, Denso modern solenoid-style injectors replace the Bosch piezoelectric units used in the LML and for the first time the injection pump is supported by a lift. pump. Different aluminum heads flow a little more air, the variable geometry turbocharger is produced by BorgWarner (not Garrett), sports a 61mm billet compressor wheel and is all controlled and operated electronically. As a result, the latest and greatest Duramax on the market delivers 445hp and a mountain-sleeping 910 lb-ft of torque off the showroom floor. Check out the table top scrolling!
Common 6.6 Lly Duramax Problems And How To Fix Them
Now, the worst part for L5P is that it is very new. Although we know that the new Denso injection system has a lot of performance, we don’t know how reliable it is. The same can be said for the best, all-electric BorgWarner turbocharger that sits in the valley. Although everything looks good on paper, it has not been proven that it can be trusted, day by day, like its predecessors. Only time will tell.
For its use the standard Bosch system has been tested based on the long CP3, pre-DPF exhaust system and its use. performance alone, we are big fans of the LBZ Duramax. It improved on the LB7 and LLY base with a stronger block, stouter connecting rod, higher pressure setting (26,000 psi vs. 23,000 psi) and came equipped with an automatic transmission that six-speed Allison. With an LBZ-powered ’06-’07 Chevy or GMC HD you got double the mileage, you saw an increase in fuel economy. u, very happy with the reliability and still has a clean body (and looks better). Without a turbo or afterburner mods (other than tuning), you can throw in the 12s in the quarter mile with a ¾-ton 4×4 crew cab. Trust us, there’s a reason these 13-year-old batteries are still bringing in $20K on the used truck market. Do 20×12 -51 wheels on 33″x12.5″ tires fit on a 2006 Chevrolet Silverado 2500 HD 4WD with OEM Stock?
Yes they do! This 2006 Chevrolet Silverado 2500 HD is running Vision Rocker 20×12 wheels, Federal Couragia Mt 33″x12.5″ tires with OEM Stock suspension, and needs tuning the metal is small and there is a slight drop throughout. As you can see from the pictures the wheel and tire combination is doable!** On this 2006 Chevrolet Silverado 2500 HD, the setting is Super Aggressive 3″-5″. Also keep in mind the fit of the spacers effect, this ride runs No front and No rear.
