Description

 

Diesel Engines Parts Known to Have Problems
 
The most frequently occurring diesel problems concern the following key engine parts, many of which (although not all) are in conjunction with the above issues:
 
Pistons
 
Pistons are an important part of the engine and can fail in several ways. These include:
 
1. The timing belt snapping.
 
2. Piston rings becoming worn out.
 
3. Piston slap (a noisy piston).
 
4. The piston becoming burnt (usually by dirty fuel injectors).
 
5. The piston becoming cracked (caused by frequent use of poor quality fuel).
 
Gaskets
 
The most frequent cause of failure in gaskets is overheating via coolant leaks. However, in general, diesel engines are more prone to gasket failure than other engine types, largely because diesel gaskets regularly face higher combustion pressures. Repair of diesel gaskets is made all the more complicated (although not impossible) by the intricate nature of diesel engines.
 
Cylinder heads
 
Problems related to cylinder heads are usually categorised by loss of compression. Cracks in cylinder heads which lead to leakages are also a common issue, as are internal casting defects.
 
Bearings
 
Bearings face a lot of stress due to the daily friction they experience- insufficient lubrication can therefore lead to bearing (and consequently engine) failure. Other causes of bearing damage include an improper selection of bearing material for the engine type at hand.
 
The most common problems with diesel engines will incorporate a mixture of the above issues and affected diesel engine parts. However, it must be emphasised that the above offers a simple overview only, and additional diesel problems certainly exist. Each issue is multi-faceted, with parts affected and displayed in numerous ways.
 
Solutions to Common Diesel Engine Problems
All diesel engines are different, and as such when it comes to problems with diesel engines there’s no ‘one size fits all’ solution for any diesel engine problem, whether common or uncommon. It must also be noted that it’s imperative to determine the cause of the diesel problem and address this issue before simply replacing damaged parts and re-assembling the engine.
