When it comes to the performance of a skid steer, particularly older models like the New Holland LX885, one of the more concerning issues that operators may encounter is blowby. This term refers to the phenomenon where combustion gases escape from the engine’s cylinders into the crankcase. Blowby can be an indication of underlying engine problems, but it’s not always something that requires an immediate engine overhaul. Understanding the causes, symptoms, and possible solutions is crucial for maintaining a skid steer’s performance and longevity.
What is Blowby?
Blowby is a term used in engine mechanics to describe the leakage of combustion gases past the piston rings into the crankcase. During the combustion process, these gases are supposed to remain inside the combustion chamber, but due to wear or other issues, some of them escape into the crankcase. This can result in a buildup of pressure inside the engine, which might affect the performance and efficiency of the machine.
While minor blowby may not immediately compromise the engine, excessive blowby is a sign of engine wear that could lead to significant performance problems. If not addressed, blowby can lead to oil contamination, reduced engine power, and, in extreme cases, complete engine failure.
Causes of Blowby
Several factors can contribute to blowby, including but not limited to:

1. Worn Piston Rings: Over time, the piston rings in an engine can wear out. As they wear, they lose their ability to form a tight seal between the piston and the cylinder wall, allowing gases to leak into the crankcase.
   
2. Cylinder Wear: If the cylinder walls become worn or damaged, they can no longer maintain an effective seal with the piston rings. This increases the likelihood of blowby occurring.
   
3. Improper Engine Maintenance: Lack of regular maintenance can lead to excessive blowby. For instance, failing to change the oil or air filters on time can lead to engine inefficiencies that contribute to the problem.
   
4. Faulty Crankcase Ventilation System: The crankcase ventilation system is designed to remove excess gases from the crankcase. If this system is clogged or damaged, it may cause a pressure buildup, leading to blowby.
   
5. Age of the Engine: As an engine ages, its internal components naturally wear down, which can lead to a higher likelihood of blowby. This is especially true for older machines with many operating hours.
   

1. Increased Smoke from Exhaust: One of the most common symptoms of blowby is an increase in the amount of smoke coming from the exhaust. This smoke may appear as blue or white, indicating that oil is being burned due to the loss of combustion gases into the crankcase.
   
2. Oil Contamination: Blowby gases can contaminate the engine oil, leading to a milky or foamy appearance. This contamination occurs when water vapor from the exhaust condenses in the oil, which can reduce the oil’s effectiveness at lubricating engine components.
   
3. Loss of Power: Blowby can reduce the efficiency of the engine, leading to a noticeable loss of power during operation. You might also notice that the engine is struggling to reach its usual operating speeds or handle heavy loads.
   
4. Pressure Build-up in the Crankcase: Excessive blowby leads to increased pressure in the crankcase. This can sometimes cause oil to leak from the seals or vents. If left unchecked, this pressure buildup can damage engine components over time.
   
5. Rough Engine Idle: A rough idle or engine stalling may occur when blowby is present. This is due to the engine’s inability to maintain smooth combustion because of the loss of gases and contamination of the oil.
   

1. Visual Inspection: Begin by inspecting the exhaust for unusual smoke. If smoke is visible, check for color changes (blue or white), which can indicate blowby.
   
2. Check the Crankcase: Open the oil fill cap and observe the crankcase for excessive pressure or smoke. If there is noticeable pressure or smoke coming from the cap, this could indicate a blowby issue.
   
3. Perform a Compression Test: A compression test measures the pressure generated by each cylinder during the combustion process. If a cylinder shows low compression, it may be a sign of worn piston rings or cylinder walls, which can contribute to blowby.
   
4. Oil Analysis: Take a sample of the engine oil and inspect it for any signs of contamination, such as a milky appearance. Oil contamination is one of the clearest signs that blowby is occurring.
   
5. Crankcase Ventilation Check: Ensure that the crankcase ventilation system is working properly. If the system is blocked, excess gases will accumulate in the crankcase, worsening the blowby problem.
   

1. Engine Overhaul: In cases where blowby is caused by severe engine wear (such as worn piston rings or cylinders), an engine overhaul may be necessary. This involves removing the engine, disassembling it, and replacing worn components like pistons, rings, or seals.
   
2. Crankcase Ventilation Repair: If the blowby is caused by a clogged or malfunctioning crankcase ventilation system, cleaning or replacing the ventilation components may resolve the issue. Ensuring that the crankcase is properly vented can prevent pressure buildup.
   
3. Oil Change and Filter Replacement: While this is a temporary fix, changing the oil and replacing the filters can help remove some of the contamination caused by blowby. This can also prevent further damage to the engine in the short term.
   
4. Compression and Cylinder Head Repair: If the blowby is due to low compression in certain cylinders, repairing or replacing the cylinder head or piston rings may help. In some cases, reboring the cylinders and fitting oversized pistons can restore compression.
   
5. Regular Maintenance: Preventative maintenance is crucial for avoiding blowby in the first place. Ensure that the oil, air filters, and other engine components are regularly maintained to prevent excessive wear and tear.

Dredging is a vital process in the mining, construction, and environmental industries. One of its common applications is sand dredging, a procedure used to extract sand from bodies of water, such as rivers, lakes, or the seabed. This sand is then used in construction, landscaping, manufacturing, and various other industries. The process of dredging sand is complex, involving specialized equipment and techniques, and is subject to a number of environmental, regulatory, and technical challenges.
Understanding Dredging and Its Purpose
Dredging is the process of removing material from the bottom of bodies of water. While dredging can involve the removal of various types of material, sand is one of the most commonly extracted substances. Sand dredging is typically used to clear waterways, create or maintain navigation channels, or to obtain sand for use in various industries, particularly construction.
In construction, sand is essential for making concrete, mortar, and other building materials. It is also used for land reclamation, beach nourishment, and other civil engineering projects. Dredging helps to provide a steady supply of sand, especially in areas where natural sand deposits are running low or where sand is in high demand.
The Sand Dredging Process

1. Site Selection and Planning
   Before any dredging work begins, it is important to select the appropriate site and conduct a thorough survey. Factors such as the location of sand deposits, the depth of the water, environmental concerns, and regulatory requirements all play a role in determining the feasibility of a dredging project.
   Planning also involves considering factors such as the type of dredging equipment required, the potential impact on local ecosystems, and the logistics of transporting the dredged material.
   
2. Dredging Methods
   There are several methods used in sand dredging, each suited to different types of environments and project requirements. The most common dredging techniques include:
   • Hydraulic Dredging: This method uses a pump to suck up sand from the riverbed or seabed. The sand is then transported through a pipeline to a designated site for disposal or processing. Hydraulic dredgers are efficient and can be used in deep or shallow water.
     
   • Mechanical Dredging: This technique involves using a bucket or a clamshell grab to scoop sand from the waterbed. It is more suited to shallow water or areas where the sand is compacted. Mechanical dredging is often used for smaller, localized dredging projects.
     
   • Cutter Suction Dredging: This advanced dredging method uses a rotating cutter to loosen sand and other materials from the bottom of the body of water. Once loosened, the material is sucked up by a suction pipe. Cutter suction dredgers are commonly used in deeper waters and for more challenging projects.
     
3. Transportation and Processing of Sand
   Once the sand is dredged, it is transported to shore, where it can be processed or used immediately. In some cases, the sand is simply pumped to a nearby shore, where it can be used for construction or land reclamation. In other cases, the sand may undergo processing, such as washing, sorting, or grading, to remove impurities or to achieve the desired specifications for various industrial uses.
   The transportation of dredged sand is an important logistical consideration. Depending on the location of the dredging site, sand may need to be transported overland by truck or conveyor systems, or by water using barges.
   

1. Environmental Impact
   Sand dredging can have significant environmental impacts, particularly on aquatic ecosystems. Removing large amounts of sand from riverbeds or seabeds can alter the natural habitat for fish, plants, and other marine life. It can also affect the flow of water, leading to erosion or changes in water quality.
   To mitigate these impacts, many dredging projects are subject to strict environmental regulations. In some cases, dredging projects must conduct environmental impact assessments, which evaluate the potential risks to local ecosystems. Additionally, dredging operators must take precautions to avoid disturbing the surrounding environment, such as minimizing turbidity (cloudiness) in the water and ensuring the safe disposal of dredged material.
   
2. Regulatory Challenges
   Dredging operations, especially for sand extraction, are closely regulated in many countries. Governments often require dredging permits, and operators must comply with local, national, and international regulations. These regulations govern everything from where dredging can take place to the methods used and the disposal of the material.
   In many cases, dredging companies are also required to maintain records, provide environmental monitoring reports, and demonstrate that they are operating within the legal boundaries set by regulatory bodies. Failure to comply with these regulations can result in fines, legal action, or even the suspension of operations.
   
3. Equipment and Operational Costs
   The costs associated with dredging operations can be high, particularly when dealing with large-scale sand dredging projects. Equipment costs, fuel, labor, maintenance, and environmental monitoring all add up quickly. Additionally, the dredging process itself can be time-consuming, depending on the depth of the material to be removed and the methods used.
   Specialized dredging equipment, such as hydraulic dredgers and cutter suction dredgers, can be expensive to operate and maintain. These machines require skilled operators and regular maintenance to ensure they are functioning efficiently. For companies involved in dredging, balancing the costs of operation with the need for efficient, high-output machines is crucial.
   
4. Sand Quality and Processing
   The quality of sand extracted through dredging can vary significantly, depending on the location and the type of sediment being dredged. In some cases, the sand may need to be processed to meet specific quality standards required for its intended use, such as in concrete or other construction materials.
   Sorting and cleaning the sand often involves washing it to remove organic matter, clay, and other impurities. This process can add additional time and cost to a dredging operation, particularly if the material is contaminated or has high levels of fines (small particles that are not useful for construction purposes).
