Engine Blowby problems, most don’t need a rebuild!

Engine Blowby problems or Cylinder “Blow-by” (excessive crankcase pressure) is a common and worrying problem encountered by most truckies at some stage in their career. Concern is certainly justified, as it typically means an expensive engine rebuild is necessary, and this is usually recommended by mechanics and dealers. But, according to...

Nissan Patrol & Landcruiser Overheating Problems

Time and time again, we are contacted by customers who have overheating problems with their diesel engines that they cannot rectify. Many have spent $3000 to $4000 on big core radiators, new water pumps, thermostats, fan hubs, chemical cleaning and more, yet have not fixed the problem. The typical pattern is that...

Cost savings boost coal production

According to the laws of physics, power is the rate of performing work. When applied to a diesel powered coal mining fleet, an increase in power results in an increase in production. Of course, a production drive is a little more complicated, but never-the-less, more power is one method of...

Cost Reductions in Driveline Maintenance

The key to this is minimizing operational stresses within gearboxes, differentials, planetaries, etc, since the less stress and loadings placed on each individual part within components, the longer everything lasts.   In this article, driveline maintenance and lubrication enhancements will be discussed. Stress reduction will require a lowering of the coefficient of...

Additives for Managing Common Rail Diesel Emission Control Equipment

Common Rail Diesel engines were introduced to meet the need for more stringent exhaust emission requirements. Fuel pumps, injectors, EGR valves, catalytic convertors and diesel particulate filters are all integral parts of the emission control system. Most of the problems encountered can be corrected and controlled with the correct use of...

Fuel and Oil Additives

There’s always been a lot of scepticism surrounding the use of fuel and oil additives, and a lot of this has its beginning with “snake oil” salesmen making claims that they simply could not deliver on. Yet today, there are more problems with deposits in modern, precision, high performance engines, than...

More power and torque

If you think that new vehicle performance is as good as it gets, then you’re in for a pleasant surprise! As advanced as modern petrol and diesel engines are, there are still substantial inefficiencies that prevent more power and torque from reaching the wheels. Most notable is internal frictional losses, and...

Solving Common Rail Diesel Problems

The Common Rail Diesel (CRD) injection system is the most recent development to achieve ever more stringent diesel exhaust emission standards, but it is currently associated with widespread problems, including engine rattles, expensive injector and fuel pump failures, injector sticking, stalling problems and rapid piston and liner wear. Problems have...
