At the last Diesel Power Challenge we met Dmitri Millard, who was part of Matt Larson's crew from Utah. These hard-core diesel enthusiasts loaded up their Silverados with tools and parts, then traveled across the country to compete. After the event they drove home. That's right, no trailer for these race vehicles. Dmitri's truck, which is featured on page 66, is in training for DPC 2010. Recently, Dmitri gave us a call to let us know what he was up to. As we found out, it's not always racing for the diesel enthusiast-sometimes it's business, or fun, or a mixture of the two. He was going to be in our neighborhood (Southern California) installing a 6.6L Duramax engine for two other diesel enthusiasts-Paul and Drew Benham. Paul is very active in motorsports and his son Drew started his first diesel club when he was just 13 years old. Here is the Benham's trailer, which got this Duramax driveway rebuild started. Their first tow vehicle was a Chevy van with a 454ci gasoline engine that struggled against the Karry-All's 13,000-pound gross weight. When they upgraded to their currently owned '01 Silverado with the 6.6L Duramax, they appreciated the increased torque of the diesel. Still, they wanted more power, so they upgraded the truck's fueling and selected aggressive electronic engine calibrations. Here is the Benham's trailer, which got this Duramax driveway rebuild started. Their first Here are the results of a blown head gasket that was not addressed in time. As you can see, the stock head bolts broke off during disassembly. The head was stuck to the block and it took quite a bit of force to pry it apart. The heads and block were trashed. Still, it was nice to have them around for extra parts and as an example. In hindsight, the Benhams wish they would've stepped up to head studs before they did any performance modifications. Here are the results of a blown head gasket that was not addressed in time. As you can see After the teardown it was easy to see the 6.6L Duramax is a traditional 90-degree V-8, while the new 4.5L Duramax will be a 72-degree V-8. After the teardown it was easy to see the 6.6L Duramax is a traditional 90-degree V-8, whi Dmitri Millard helped create a backdrop for the 6.6L Duramax he brought down from Utah in the back of his Silverado. This engine is an LB7, which GM used from '01 to '04. More specifically, it has the California emissions package that includes a different glow plug harness. Dmitri Millard helped create a backdrop for the 6.6L Duramax he brought down from Utah in Whenever you acquire a used engine, it's important to examine it and see what unfound problems caused the original owner to choose to get rid of it. Here is an example, notice the orientation of the oil pressure sensor. It is difficult to tell now after the engine was cleaned, but there was oil leaking from this area. Whenever you acquire a used engine, it's important to examine it and see what unfound prob The Benham's junk Duramax proved useful as we could see how the oil pressure sensor was designed to fit. Having a partial engine around is very helpful and will definitely save a few trips to the parts store or dealer. We also used the bottom section of the two-piece oil pan because the new engine's pan was crushed. The Benham's junk Duramax proved useful as we could see how the oil pressure sensor was de 1 | 2 | 3 | » | View Full Article By Jason Thompson Enjoyed this Post?
