Servicing The GM Duramax Diesel Engine
The question that I often hear about the Duramax is “What kind of problems do you see with these engines?” I have to admit that these engines have a great reputation. While some problems have plagued a few of the Duramax engines, there hasn’t been anything as detrimental as what other manufacturers have had to deal with. There are always going to be issues with anything that has to do with internal combustion. The best way to examine the Duramax would be to break down the engines by their generation and evaluate issues of each.
Diagnosing Rough Idle On Chrysler 2003 Town & Country
According to the owner, the 3.8L Town & Country had been driven for quite awhile with an illuminated Check Engine light and a rough idle condition. As the vehicle was driven, the idle condition worsened until the engine wouldn’t idle in gear unless the driver applied the throttle. Of course, the vehicle owner had assumed that the rough idle complaint was caused by only one component failure and would therefore be relatively simple to repair.
Variable Valve Timing (VVT) Systems Play A Direct Role In Vehicle Emissions
By the early 1990s, almost all import automotive manufacturers had a successful variable valve timing (VVT) system in production. These systems offered higher performance from smaller displacement engines at higher rpm. As these vehicles exceeded their new car warranties, technicians learned the ins and outs of these systems and how regular oil changes could increase the life of VVT components. Now, the VVT is playing a direct role in vehicle emissions and the way gases are burned in the combustion camber.
‘Exploring’ Service Needs On The Ford 4.0L V6 Engine
Rated at a rather anemic 210 horsepower, the 4.0L SOHC V6 is not exactly a high output engine. It also has an unusual overhead cam drive setup. Unlike most other OHC V6 and V8 engines that drive both overhead cams directly from the crankshaft with a belt or chain, this engine has an intermediate jackshaft in the middle of the block where a pushrod cam would normally be located.
Damage Control: Spark Plug Removal Techniques On Ford Modular Engines
The problem of removing spark plugs from various Ford Modular engines lies with excessive carbon buildup on the plugs, especially on engines that have gone beyond an OEM-recommended replacement interval. This can cause a plug to break in the chamber during its removal, creating stress on the tech and additional labor time to remove the damaged component.
Diagnostic Dilemmas: Multiple Failure Diagnostics On High Mileage Engines
Gary Goms explains that in tough economic times, a driver has no way of knowing how many maintenance-based and component-based failures will accumulate before he or she can afford to have a technician investigate the problem once a Check Engine light comes on.
Phaser-Style Variable Valve Timing System Controls And Operation
Phasers commonly can be found on just the exhaust cam or on both the intake and exhaust cams.
Memory Lane: Nuts, Bolts And Screws – Finishing A Chevy Restoration Project
Gary Goms discusses the mechanical challenges of restoring a truck that he began maintaining when he went to work in a gas station – back in 1957!
Tech Feature: Venturing Into GM Duramax Diesel Service
Back in the 1990s, GM wasn’t making too many waves in the diesel truck market. The 6.2L and 6.5L engines had been around for sometime, but they were no match for the release of the Cummins 6BT in the Dodge truck in 1989 and the Ford Powerstroke in 1994.
