When the LBZ was introduced to replace the LB7, the LB7’s injector issues had long been solved and the overheating issues associated with the LLY were a thing of the past. This engine’s beefier block casting, stronger connecting rods, higher pressure common-rail fuel system and updated ECM arguably made it the most powerful, drivable, reliable and tunable Duramax to date. Right out of the box, the LBZ produced 360hp and 650 lb-ft of torque. During this time frame (’06-‘07), these numbers not only outperformed the 6.0L Power Stroke’s 325hp and 570 lb-ft, but they beat out the 325hp and 610 lb-ft figures put up by the 5.9L Cummins as well. The LBZ was also the first Duramax to be coupled to the six-speed Allison 1000 automatic, which proved capable of handling more power than the five-speed version that preceded it.

Diesel enthusiasts longingly remember the LBZ as the last Duramax built before the modern day emissions crunch kicked in, which spawned pollution control technology that reduced fuel economy and greatly hampered long-term engine durability.  Arguably the most highly sought after Duramax ever built is the LBZ Duramax.

  • More meat exists in the lower section (big end) of the rod than what you’ll find on LB7
  • The beefier I-beam style rods bring more mass to the rotating assembly
  • Connecting rods were the strongest found in any Duramax up to that time
  • GM cast slightly more webbing into the main bearing regions of the LBZ’s gray-iron block for added horsepower and torque

Unfortunately nothing is perfect and in this case the LBZ pistons weren’t up to the task of surviving in higher horsepower applications.  The cast-aluminum pistons are highly susceptible to cracking.  The LBZ piston’s use of wrist pin bushings is also believed by many to be a contributing factor in OEM piston failure, along with a thinner wrist pin being utilized.

When a piston lets go, you definitely know it, as it’s accompanied by a nasty miss, excessive blow-by and smoke out the exhaust.

Looking at a couple of upgrades that would make it more my truck and what I want.

Ceramic Coating - DONE 3/24/2020 by Ceramic Pro

  • Clay bar service (strips all the impurities that were on your car previously)
  • Buff wax
  • blackout of exterior trim
  • 5 Layers of Ceramic Pro 9H
  • 1 Layer of Ceramic Pro Light Applied as a Top Coat
  • 1 Layer of Ceramic Pro 9H on Rims and Plastic
  • 1 Layer of Ceramic Pro Rain on Front Side Windows and Windshield
  • Lifetime Warranty

AMP Power Steps - Installed by Al on 4/5/2020

Tow Mirrors

GM OEM Tow Mirrors (boring.. no front facing turn signal) and run about $400 each (GM Part# 15904035 right & 15904034 left). Word on the reviews is they still shake just like an after market mirror does so not sure its worth the high price tag for GM Camper Mirrors.

GM_OEM_TowMirrors_2006.jpeg

BOOST Auto - $550 - purchased on 2020-04-07 (not received yet)

(Thought is bring over mirrors and Pop & Lock tailgate to Al)

 

Cab Lights

 

Truck Bed Accesories

 

Dark Tinted Windows

 

Body Repair

  • Right rear of bed is pushed in. Have Clarkston Auto Body see if they could fix it and put in rear window
  • replace rear sliding window with GM OEM (use clarkston auto body), or instead GM OEM use CRL
  • Get quote on fixing scratches, swirl marks
  • Get quote on rust proofing before winter
  • Remove chrome moldings from doors
  • replace plastic bed side covers with line-x spray

Interior/Electrical (Radio Knobs Speaker and Things)

  • replace radio (or figure out how to connect phone to an aux port)..  new radio means backup camera. -PRIORITY so I can get backup camera
  • replace rearview with compass/temp.
  • Upgrade gauges with LED lighting at Circuit Board Medics - avg $350

Misc

  • Fix headlamp (passenger side has condensation)
  • replace fog lights (worn out, dull, faded)

Saturday (2020.04.11) performed Trans Filter (internal and spin on external) replacement as well as 3 gallons of new fluid and the internal trans filter lock and a new deep sump pan. Miles: 104,000

Added EFI Live DSP5 and a TCM tune all from calibrated power (duramaxtune).  Now just trying to get the truck to find its groove.  It doesn't feel like it knows what to do. I have been keeping it in Position 1 which is the stock+ tune and I plan on keeping it here until it feels like its regained the normal shifting and driving and then I'll kick it to Position 4 which is the Eco mode to get those high miles per gallon (especially driving back and forth to Detroit for Kate's Chemo).  Then Position 2 and 3 are for towing which will also come in handy.  You can tow with Position 1 (stock+ tune) but position 2 and 3 just add some benefits you only really need when towing and its based on load. Position 2 is Heavy Load (over 8000 lbs of weight your towing) Position 3 is for Light Load (under 8000# towing).

Position 5 is for race tuning with stock equipment but could still mess up some crap so the suggestion is not not use it often if you can hold yourself back..  we know you won't be able to.

Now getting a Check Engine light when the glow plugs are trying to warm up the engine to start.  Checking for codes it shows ECM P0672 which is a bad glow plug in cylinder #2 which is about $20 for the glow plug and looks like its a do it yourself type of job.  Its like changing a skinny, tiny spark plug.
