Industrial Injection 5.9L Cummins Race Heads

The Industrial Injection 5.9L Cummins Race Heads are designed for the racer / sled puller in mind. Fully CNC ported heads complete ready to bolt on.
Heads are first jet washed in a high pressure spray cabinet to remove oil and dirt, then glass beaded to remove carbon. Next they are checked by magnafluxing, (cast iron only) or pressure testing. They are visually inspected for defects that would make them unusable. Valve guides and seats are removed as needed for porting.
Port development is accomplished using a superflow 600 flow bench with a computer recording all flow measurements.
Many things are considered when designing a cylinder head Port; air flow is only one of the things to think about. Another major concern is port wall thickness.
Anyone can get a head to produce high flow numbers, but if doing so leaves the port wall to thin the casting will crack. High performance Diesel heads are more prone to crack because of the thermal shock experienced by excessive intermittent or long term exhaust temperatures.

The porting is then preformed using a new 5 Axis CNC Cylinder Head Porting Machine with CAD/CAM software specifically designed for cylinder head porting. CNC porting brings unparalleled accuracy to head porting with each port flowing the same. This helps balance the power that each cylinder produces, making tuning easier. 
New High Strength Alloy, Heat Treated iron based valve guides are installed. These guides are heat treated to Rockwell 22 “C” Scale, which produces the ultimate in wear resistance. This is far superior to original guide material, including Bronze. The guide incorporates a spiral grove inside the guide to hold oil and aid the lubrication of the valve during engine operation. 
Guides are then honed (not reamed) to exact size using a diamond honing mandrel. Diamond abrasives allow for consistency of size, surface finish, and bore geometry with no variation from guide to guide. The guide size is then verified using a valve guide bore gauge. 
As needed the head receives new Premium valve seat inserts made from a true Nickel Based Non-Magnetic material that was developed for extreme operating conditions. 
Next the head is treated to a multi angle valve job to help maximize the flow of air in and out of the head. This is accomplished using a Serdi 100 guide and seat machine. Serdi uses a solid carbide straight shank pilot. When inserted into the valve guide, it simulates the real valve stem during the centering process. This guarantees the valve seat is finished for a perfect valve to seat match. 
Using CBN or Diamond tooling the head is given a new surface. With our berco milling machine we can control the surface finish to accommodate different head gasket types. For example MLS head gaskets require a very smooth surface finish.
Finally the head is jet washed dried and assembled with new valve seals and new performance valve springs.

Duramax 6.6L Valve Lash Adjustment

Duramax 6.6L Valve Adjustment  Duramax Diesel Pickup Truck This is one method used to set the valve lash on your duramax engine Valve adjustment should be performed anytime the heads are removed. It's also good practice to adjust valves during service that require valve cover remove.  TDC (Top Dead Center) First start with, locating the timing mark on the front engine cover and the harmonic balance.  Rotate the crankshaft in order to bring the number 1 cylinder to TDC (Top Dead Center) of the exhaust stroke. This mark should be aligned with the mark on the engine.  To adjust the valves, start by loosening all the jam nuts with a 14mm wrench, you will also need a flat screwdriver to make the adjustments. Adjust the valve using a .012" feeler gauge Use your .012” feeler gauge between the rocker arm and the valve bridge as pictured. The correct setting is had when there is slight resistance when moving the feeler gauge. It should not be so tight th

How to Remove LB7 Duramax Fuel Injectors Step By Step Instructions

LB7 Duramax Diesel 6.6L R&R Remove and Replace  Working on any automobile engine can be intimidating, and that is the very reason why mechanics stay in business, However some tasks that seem intimidating are not actually that difficult if you have the right tools and the right knowledge to complete the task at hand, The following instructions are on how to remove LB7 Duramax Fuel Injectors. This task is often considered a difficult process to complete, but these instructions will break down the process and make this task seem simple. Duramax Diesel LB7 Engine 2001-2004 GMC or Chevrolet Pick-up Truck  Drain the Coolant find the drain valve on the passenger side of the wheel well and drain the coolant. To capture the debris,use a bucket and a cloth for a filter. Caution: This step is very important to ensure the combustion chamber won't fill with coolant during the last step of removing the  fuel injectors if an injector cup pull out during this step.

Duramax Glow Plugs Operation Glow Plug Relay

                                                    Cold Weather Starts and Glow Plugs  Glow Plug System Description Duramax diesel engine, air alone is compressed in the cylinder. Then, after the air has been compressed, a charge of fuel is sprayed into the cylinder and ignition occurs, due to the heat of compression. Eight glow plugs are used as an aid to starting. The glow plug initial ON time will vary based on the system voltage and temperature. Lower temperatures cause longer ON times all the times. The ECM provides glow plug operation after starting a cold engine. This post-start operation is initiated when the ignition switch  is returned to Run, from the Start position. This operation helps clean up excessive white smoke or poor idle quality after starting. Control of the instant start system, glow plugs is determine by an electronic glow plug control unit and  4.7 volt  glow plugs, requiring  2 seconds  to heat up to  1,000°C (1,832°F)  . The temperature and t
