Australia’s forestry operations span vast and diverse terrains—from the eucalyptus-rich highlands of Tasmania to the dense pine plantations of Victoria and Queensland. Logging in this region is shaped by unique environmental conditions, strict regulatory frameworks, and a blend of traditional and mechanized practices. Despite the country’s relatively small forestry workforce compared to global giants like Canada or Russia, Australia remains a significant player in the timber export market, particularly in hardwood and plantation softwood.
A trucking operator encountered a persistent problem with a 2006 Freightliner Columbia powered by a 14-liter Detroit Series 60 (engine code 6067HV6E). The engine exhibits heavy blowby, consumes roughly a gallon of engine oil daily, and even pressurizes the coolant surge tank. The operator had a full overhaul about five years ago—new seals, gaskets, pistons, injectors, turbo, valve work, head-refacing—yet the same symptoms have recurred. Unlike the truck’s 12.7 L siblings (also with EGR removed or disabled), this 14 L variant is the only one giving trouble.
