Goldfarb and Associates is contact free drop off for Marine Corps Toys for Tots Drive Dear Friend, Every year, Goldfarb and Associates makes a donation to the Marine Corps Toys for Tots in honor of our customers, vendors and friends. This year will be no different. However, in light of the pandemic, Toys for Tots is in desperate need of toys to distribute to children in need. Here are just a few bullet points regarding this year's need. Because of the pandemic, the need is much greater than the organization has seen in recent years and they face some real challenge...

A Gift Has Been Made in Your Honor. Dear Friend,It has been an exciting year for Goldfarb and Associates. In April of this year, after twenty years in different locations, we were able to consolidate all of our operations and move to our new 25,000 sq. ft warehouse located just a few blocks away. We love our new home and we are confident that we will be able to provide even greater customer service to our loyal and valuable customers. We certainly would not have been able to do this without you, so thank you.As we have done ove...

What Are Freeze Plugs and Why Do They Fail in Diesel Engines? A freeze plug (also called a core plug) is a metal disc pressed into the engine block to seal holes left over from the sand casting process. Despite the name, these plugs were never designed as freeze protection; their purpose is structural, and they frequently fail to eject before a block cracks under freezing conditions. This guide covers freeze plug fundamentals and types, the causes and symptoms of failure, step-by-step diagnosis and replacement, engine-specific considerations and costs, ...

What Is Rear Main Seal Replacement and Why Does It Matter? A rear main seal replacement is the process of removing and installing the crankshaft oil seal at the rear of the engine block where the crankshaft exits to meet the transmission. In diesel engines, this seal operates under significantly higher thermal and mechanical stress than in gasoline applications, making its integrity critical to preventing oil loss, component contamination, and costly downtime. This guide covers leak symptoms and diagnosis, root causes of seal failure, installation be...

What Is the Difference Between Diesel Knock and Gasoline Knock? Engine knock is abnormal combustion that produces destructive pressure waves inside the cylinder, but it occurs through fundamentally different mechanisms in diesel and gasoline engines. Diesel knock results from prolonged ignition delay that allows excess fuel to combust simultaneously, while gasoline knock happens when unburned end-gas auto-ignites before the spark-initiated flame front reaches it. This guide covers combustion fundamentals, diesel knock causes and prevention, gasoline knock...

Oil Pump Selection: Maintaining Proper Lubrication Pressure in High-Mileage Diesel Engines Low oil pressure on a high-mileage diesel engine is never just a gauge problem. Research published in Frontiers in Mechanical Engineering (PMC) confirms that 90% of bearings fail to reach their expected service life due to lubrication problems, a figure that underscores why proper oil pump selection matters so much when worn internal clearances quietly increase the engine's demand for oil faster than most owners realize. A pump that could barely keep up when new will fall short well befor...

Complete Engine Gasket Sets: What's Included and Why Quality Matters Engines rely on tight seals to run efficiently, and a complete engine gasket set ensures all critical joints stay leak-free. From oil passages to combustion chambers, the right gasket set helps maintain performance and prevent costly repairs down the road. According to a report by the U.S. Environmental Protection Agency, defective engine gaskets can allow coolant to enter the engine, which contributes to increased emissions and potential engine damage over time, highlighting the importance o...

Head Gasket Selection: MLS vs. Composite for Different Diesel Applications Head gasket selection becomes especially important in diesel engines due to high compression and continuous operating loads. The choice between MLS head gaskets and composite head gaskets affects sealing strength, heat control, and durability across different diesel applications, from light-duty engines to heavy-duty commercial use. According to a published diesel engine failure analysis study, diesel engine component failures account for nearly 41% of total engine failures. Gaskets fall with...

Water Pump Failure Signs: Preventing Overheating and Engine Damage The water pump helps keep a diesel engine at a safe temperature by moving coolant through the system. When it works properly, heat stays under control and engine components remain protected during normal operation. According to the National Academies Press, about 50% of the fuel energy used by typical heavy-duty diesel engines is lost as heat rather than converted into useful mechanical power. Of that total, roughly 24% is rejected through the engine cooling system, while another 26% escapes ...

Camshaft Followers vs. Lifters: Maintenance and Failure Prevention Cam-driven motion systems sit at the core of industrial machinery and automotive engines, converting rotational camshaft movement into precise linear action. Components such as camshaft followers and lifters regulate timing, load transfer, and motion accuracy under constant stress. Their performance directly influences efficiency, wear rates, and long-term reliability across demanding operating environments. In fact, industrial manufacturers face significant risk from sudden stoppages: unpla...

Valve Stem Seals: Small Parts That Prevent Major Oil Consumption Issues Engines that burn oil can surprise their owners with frequent top-offs or blue smoke from the exhaust. Many modern passenger engines use less than 0.05 % oil relative to fuel consumption under normal conditions, and higher rates often point to internal control issues like worn seals. Even a tiny part like a valve stem seal can let oil enter the combustion area when it no longer seals tightly. When that happens, oil burns with the fuel instead of staying where it protects metal parts, leading ...

Cylinder Head Torque Sequences: Why Order and Specifications Matter Cylinder head failures often start when bolts receive force in the wrong order or to the wrong level. Uneven pressure can distort the head or weaken the seal, even on a healthy engine. These issues may stay hidden at first, then surface later as leaks, loss of performance, or costly repairs. Even slight changes in tightening order or force can shift pressure across the head. That imbalance stresses components unevenly, increasing the risk of gasket failure, leaks, and long-term engine damage....

How to Select the Best Fuel Injectors for Your Diesel Engine: A Buyer's Guide Diesel fuel injectors are precision components critical to engine performance, fuel economy, and emissions compliance. When symptoms like rough idling, white smoke at startup, or oil dilution appear, they often signal that an injector has failed or drifted out of tolerance. These clogged fuel injectors symptoms causes are frequently the result of carbon buildup or fuel contamination, which disrupts the fine spray pattern required for complete combustion and can lead to expensive engine damage...

Best Materials for Fuel Nozzles: Durability and Performance Guide Fuel nozzles are small but mighty parts of any engine or fuel system. They control the spray and flow of fuel, directly impacting combustion, efficiency, and overall performance. But not all fuel nozzles are created equal, especially when it comes to the materials used in their construction. Choosing the right material can mean the difference between long‑lasting durability and costly replacements. A study found that injector geometry and material details resulted in approximately 11% lower ...

How the Delivery Valve Design Affects Fuel Pressure Control Fuel pressure control in a diesel engine primarily relies on one often-overlooked component: the delivery valve. This small valve determines how smoothly pressure builds and releases in the fuel lines, directly influencing injection timing, combustion stability, and overall engine efficiency. For context, modern common-rail systems routinely operate at injection pressures above 200 MPa (2,000 bar), which amplifies the influence of delivery-valve dynamics on pressure waves and injector closur...
