The 6.6 Duramax™ LBZ was manufactured from 2006-2007 VIN Code "D"

You will receive the long block, as pictured, along with the new oil pump & the long block gasket set.  You will need to follow the installation instructions found under the documentation tab on the home page.  A copy of the installation instructions (along with various other documents for your review) will be included with the long block shipment. 

PLEASE READ & REVIEW THE INSTALLATION INSTRUCTIONS WITH THE INSTALLER!

Our Remanufactured 6.6L Duramax Long Blocks are assembled using Mahle, Federal Mogul, Hastings, Melling, Silvolite, SBI, and Elgin parts.  New Piston Kits, Rod Bearings, Main Bearings, Cam Bearings, Long Block Gasket Set, Oil Pump, and several Valve Train parts are replaced.

We do not use Cylinder Sleeves to repair damaged Cylinders in the Duramax. 

 Some Remanufacturers may install sleeves in the LBZ, we do not due to the fact they will eventually fail.

 

The Long Block is assembled as pictured above to include the following: 

Cylinder Block & Rotating Assembly (Crank, Rods, Pistons)

Camshaft, Lifters & Timing Gears

Cylinder Heads (includes Valves, Springs, Seals, Retainers, Injector Sleeves & Locks) are installed.

Valve Train (Pushrods & Rocker Arms) components are installed and lifter pre-load is set.

Oil Pump (not installed, shipped with the Long Block)

Long Block Gasket Set (refer to product description or"whats in the gasket set" under the support tab for details)

The Gasket Set will Include the Following: 

Front and Rear Crank Shaft Seals & Wear Sleeves - Front Cover - Exhaust Manifold - Water Pump - Glow Plug O-Rings - Oil Indicator Tube - Oil Filter Gasket - Timing Cover - Turbo Charger.

ANY GASKET NOT INCLUDED WITH THE LONG BLOCK  MUST BE PURCHASED SEPARATELY.

All engines are blueprinted.  Blueprinting is defined as removing or narrowing the tolerances found in mass production engines. The rod, main, & cam clearances are measured with dial bore gauges & micrometers. Bearings clearances are set depending on application (truck, car, marine, performance, etc.). Piston & valve guide clearances are set with dial bore gauges. Cam timing events are measured and adjusted. A specification and build sheet are available for each engine.

We do not weld or repair cracked blocks or heads.  We do not weld damaged crankshaft journals. We do not spray weld any components in the machining process.

Cylinders are bored in  CNC Machining centers (unless they are wet sleeve blocks) & honed in a Sunnen CNC cylinder hones with diamond abrasives (OEM technology).

Main bearing saddles are align honed or align bored.  This is part of the blueprint process. We do not try and repair blocks with "spun" main bearings.

Block decks are resurfaced with CBN cutters in CNC Machining centers. This is the latest technology in surfacing cast iron.  We achieve single digit RA figures for MLS head gaskets which is critical. To ensure proper gasket sealing we check all surfaces with a prolifometer, a device used to check surface finish to ensure gasket life and efficiency. We do not use head gasket "shims" to correct block height errors.

Crankshafts are heat treated in our thermal convection oven, which is better and easier on the casting than the standard production rebuilder's thermal oven, shot peened to relieve casting stresses, and machined a maximum of .010 on rod & main journals. Our crankshafts are then balanced in a Stewart Warner digital balancer. No welded crankshaft journals! No rear seal "speedie" sleeves, which will leak over time!  Most all production rebuilders do not balance their cranks, rods, & pistons.

Connecting rods are also heat treated, shot peened and machined to OEM specifications. This is part of blueprinting process. Matched & balanced sets of rods. We do not try to recondition rods with "spun" bearings.

Cylinder heads are remanufactured to exceed OEM specifications in a Rottler or Serdi valve seat machines. Valve guides are replaced & honed in  Sunnen guide hones. Head gasket surfaces are refinished with CBN or PCD cutters, the latest technology in the resurfacing of cast iron and aluminum to ensure a proper gasket seal. Surfaces are then checked with the same prolifometer used on block gasket surfaces.

We do not weld or repair cracked or damaged cylinder head castings. We do not "shim" weak valve springs to increase pressure, they are replaced. We do not use bronze valve guide liners like some production rebuilders as they will commonly fail. We replace the valve guide we do not try to repair it.

All assembled long blocks are tested for compression before shipping. Our engine builders are ASE master engine machinist.
