Tech Tip: What is Acceptable Oil Consumption in Diesel Engines?
There’s no simple answer to that question. Many factors can contribute to oil consumption, and correctly diagnosing if there is a problem and what’s causing it can save you a lot of money and down time. All engines will consume some amount of oil, and as an engine ages and wears we generally accept increases in consumption, but in low mileage or low hour engines oil consumption can be frustrating.
Tech Tip: Performance Diesel Engine Service Notes
Diesels are setting all kinds of records from land speed to elapsed time. So if you’re not already dabbling in diesel performance, you may be soon. Diesel engines are a different type of animal when compared to gasoline engines. While both use the same four-stroke cycle of combustion, diesels use the heat of compression rather than a spark to ignite the air/fuel mixture.
Tech Feature: Taking on Diesel Turbo Service
In the aftermarket, there are so many upgrades for turbos, especially on the mid-size diesel trucks. So how do you determine which one is right for your application?
SafeShop: Diesel and Gasoline Exhaust
Diesel and gasoline exhaust can be hazardous to employees working in dealerships and automotive services businesses. And not just those working in the shop are at risk; office employees can also be exposed through poor ventilation systems. Zurich provides information on how to help protect your business and your employees.
ATA Offers Free Training on Hybrids, CNG and Biodiesel Technology
The Automotive Training Authority (ATA) is offering free “green” aftermarket training courses on hybrid, compressed natural gas (CNG) vehicles and biodiesel/clean diesel technology. The courses, geared toward automotive repair shop owners, technicians and fleet maintenance managers, are made possible through a federal alternative fuel training grant.
Tech Tip: Sheared Crankshaft Sprocket Keys Found on Some GM 6.2L Diesel Engines
A new, hardened washer, p/n 23504011, is available for improved clamp load of the crankshaft sprocket to the crankshaft by the crankshaft bolt. Installation torques for the hardened washer have been increased to 177 to 185 ft.lbs. (240 Nm /250 Nm).
Tech Feature: Fuel for Thought About Diesel Formulations
Since 2007, the anatomy of diesel fuel at the pumps has changed. And with these changes there are legitimate concerns that diesel vehicle owners (and engine builders) need to be aware of.
Tech Tip: Turbocharged Diesels Need a Mighty Tough Air Filter
Neglecting air filter maintenance on a normal aspirated gas engine can result in poor engine performance, poor fuel economy and high emission output. Neglect the same service on a turbocharged diesel engine and some major engine and turbocharger damage can be incurred.
Tech Feature: Diesel Crankshaft Basics
Whether in a gasoline or diesel-powered engine, the crankshaft is a key component. With diesels, the crank is typically thought of as bigger, heavier and harder to get in the aftermarket. Some preconceptions are factual, say experts, while others are unfounded.
Tenneco Readies Broad New Line of Walker Light- and Medium-Duty Diesel Emissions Components
Tenneco Inc. is taking the lead in helping the automotive aftermarket capture light-duty and medium-duty diesel aftertreatment service opportunities through the development of a broad new line of replacement diesel particulate filters (DPF) and diesel oxidation catalysts (DOC).
