(Washington Insider Magazine) – In the world of car enthusiasts, oil catch cans have long been favored as an aftermarket modification to enhance engine performance. These devices are designed to capture oil vapors and contaminants, preventing them from entering the engine’s intake system. This seemingly beneficial upgrade has gained popularity as vehicle emissions continue rising. However, there’s a catch, in some states, the use of oil catch cans is illegal. In this article, we will delve into the answer: why are oil catch cans illegal?
The Purpose of Oil Catch Cans
Before delving into their legality, let’s first understand the purpose of oil catch cans. These devices act as a barrier, preventing oil and other harmful substances from entering the engine’s intake system. By doing so, they help avoid potential issues such as reduced engine performance and increased engine wear. Oil catch cans are especially valuable for car enthusiasts seeking to optimize their engines and protect them from wear and tear.
The Environmental Impact
While oil catch cans seem beneficial on the surface, the legality issue arises due to their impact on emissions control systems. The Positive Crankcase Ventilation (PCV) system is an integral part of the engine’s emissions control, responsible for recirculating harmful emissions back into the engine for burning. However, when an oil catch can is introduced into the equation, it intercepts the blow-by gases, preventing their recirculation.
The Root of Illegality: Why Are Oil Catch Cans Illegal?
The primary reason for the question: Why are oil catch cans illegal lies in this alteration of the PCV system? Modifying the emissions control system disrupts the proper recirculation of harmful gases, leading to potential environmental consequences. The increased pollution resulting from uncontrolled emissions can degrade local air quality and contribute to ecological damage. Consequently, these states have decided to outlaw oil catch cans to preserve environmental health and adhere to emissions regulations.
Warranty Concerns
Beyond the environmental impact, there’s another crucial factor contributing to the illegality of oil catch cans, warranties. When a car owner installs an oil catch can, it involves altering the PCV system, a fundamental part of the engine’s design. Such modifications have the potential to cause damage or reduce the engine’s lifespan. As a result, many manufacturers consider these alterations as a breach of warranty terms. Hence, using oil catch cans may void the warranty, leaving car owners vulnerable to expensive repairs or replacements.
Alternatives for Car Enthusiasts
For car enthusiasts living in states where oil catch cans are illegal, the prohibition doesn’t necessarily mean they must abandon their desire to optimize engine performance and protect their vehicles. Several alternatives can achieve similar results without violating regulations or warranty terms.
One of the best alternatives is regular maintenance. Routinely checking and changing the engine’s oil, using high-quality filters, and adhering to recommended service intervals can significantly improve engine performance and longevity.
Another option is to invest in advanced engine technologies offered by reputable manufacturers. Many modern vehicles come equipped with efficient emissions control systems that reduce the need for aftermarket modifications.
Conclusion: Why Are Oil Catch Cans Illegal?
Oil catch cans, once a favorite upgrade among car enthusiasts, have found themselves at the center of an environmental and legal controversy. The disruption caused to the PCV system and the potential increase in harmful emissions have led some states to label them illegal. Furthermore, these modifications may void engine warranties, adding another layer of concern for car owners.
While the allure of improving engine performance is strong, it is crucial to respect emissions regulations and prioritize the preservation of our environment. For car enthusiasts seeking to optimize their engines, exploring alternative, legal options remains the responsible and eco-friendly approach.
