Complete Buying Guide for Best Oil Catch Can For 5.7 Hemi
Choosing the best oil catch can for your 5.7 Hemi involves more than just picking a flashy model. It’s about ensuring your investment truly protects your engine. This guide will walk you through the essential factors to consider, helping you make an informed decision and safeguard your Hemi’s performance for years to come.
Essential Factors We Consider
When selecting an oil catch can for a 5.7 Hemi, several key elements influence its effectiveness and your satisfaction:
- ✓ Vehicle-Specific vs. Universal Fit: While universal catch cans can work, a vehicle-specific oil catch can designed for the 5.7 Hemi will generally offer a more precise fit, easier installation, and optimized hose routing. This often means custom brackets and hoses that perfectly integrate with your engine bay.
- ✓ Baffled Design: This is arguably the most crucial feature. A good oil catch can must have internal baffles or a multi-chamber filtration system. These baffles help cool the oil vapor, causing it to condense into liquid and drop to the bottom of the can, preventing it from reaching your intake manifold. Simple empty cans are far less effective.
- ✓ Capacity: The can’s capacity dictates how frequently you’ll need to empty it. For a daily driver 5.7 Hemi, a capacity of 3-4 ounces (around 100-120ml) is generally sufficient for several thousand miles, but larger capacities (like 400ml) offer even less frequent maintenance. Consider your driving habits; if you drive long distances or in extreme conditions, a larger capacity might be beneficial.
- ✓ Material and Durability: Most high-quality oil catch cans are made from billet aluminum. This material is lightweight, durable, and dissipates heat effectively, aiding in vapor condensation. An anodized finish not only adds to aesthetics but also provides corrosion resistance.
- ✓ Hose Quality and Fittings: The hoses and fittings are critical for a leak-free and reliable system. Look for catch cans that come with high-quality, reinforced, or braided hoses that won’t collapse under vacuum. Secure, O-ring sealed fittings are also essential to prevent leaks.
- ✓ Ease of Installation and Maintenance: An ideal oil catch can for your 5.7 Hemi should be relatively easy to install, with clear instructions and all necessary hardware. Features like a dipstick or a removable base make checking fluid levels and draining the collected oil a simple task.
- ✓ Drain Mechanism: Consider how the can is emptied. A threaded, removable base is common and effective. Some advanced designs might include a drain valve, which can be even more convenient.
- ✓ Breather Filter vs. Sealed System: Some catch cans come with a breather filter, allowing the system to be vented to the atmosphere, while others are designed as sealed systems. Both have their merits, and the choice often comes down to local emissions regulations and personal preference. A sealed system is generally preferred for street vehicles to maintain emissions compliance.
Budget Planning
The price of an oil catch can for a 5.7 Hemi can vary significantly, typically ranging from $50 to over $200. While it might be tempting to opt for the cheapest option, remember that a low-cost, poorly designed catch can could offer minimal protection or even create new problems. Allocate a budget that allows for a quality product, especially one with a baffled design and durable components. Consider the long-term savings in engine maintenance and potential repair costs that a good catch can can provide. Our “Best Budget” pick offers a great balance of performance and affordability, proving that effective engine protection doesn’t always require the highest price tag. Factor in potential additional costs like upgrading hoses if a universal kit’s included ones aren’t up to par.
Final Thoughts
Investing in the best oil catch can for your 5.7 Hemi is a proactive step towards preserving your engine’s health and performance. By effectively separating harmful oil vapor and contaminants, you’re preventing carbon buildup, improving combustion efficiency, and ultimately extending the life of your valuable Hemi engine. Take the time to consider the factors outlined above, read customer reviews, and choose a product that aligns with your vehicle’s specific needs and your driving style. A well-chosen oil catch can is a small but mighty upgrade that pays dividends in the long run.
Frequently Asked Questions
Q: What does an oil catch can do for a 5.7 Hemi?
A: An oil catch can is designed to capture oil vapor, unburnt fuel, and moisture that are typically recirculated back into your engine’s intake manifold through the PCV (Positive Crankcase Ventilation) system. For a 5.7 Hemi, this means preventing carbon buildup on intake valves, keeping the intake system clean, and ultimately prolonging engine life, maintaining performance, and reducing harmful emissions.
Q: Is an oil catch can really necessary for my 5.7 Hemi?
A: While not strictly “necessary” for your engine to run, installing an oil catch can on a 5.7 Hemi is highly recommended. Direct injection engines (and even port-injected engines like some Hemi variants, especially when coupled with MDS) are particularly susceptible to carbon buildup. This buildup can lead to reduced fuel economy, decreased power, misfires, and costly repairs over time. A catch can is a proactive measure that significantly mitigates these risks, making it a valuable investment for long-term engine health.
Q: How often should I empty my 5.7 Hemi oil catch can?
A: The frequency depends on the catch can’s capacity, your driving style, and environmental conditions. Generally, it’s recommended to check and empty your 5.7 Hemi oil catch can every 1,000 to 5,000 miles, or at every oil change interval. In colder climates or with aggressive driving, you might find more accumulation, necessitating more frequent checks. Many manufacturers, such as J&L, suggest checking after 1000 miles and draining between 2500-3500 miles, but always refer to your specific product’s recommendations.
Q: Can I install an oil catch can myself on my 5.7 Hemi?
A: Yes, installing an oil catch can on a 5.7 Hemi is generally considered a straightforward DIY task for most mechanically inclined individuals. Most kits, especially vehicle-specific ones, come with all necessary hardware, hoses, and detailed instructions. Tools required are typically basic hand tools like wrenches, screwdrivers, and possibly hose cutters. If you’re uncomfortable with vehicle modifications, professional installation is always an option.
Q: Are there any downsides to using an oil catch can on a 5.7 Hemi?
A: The downsides are minimal. The primary “downside” is the need for periodic maintenance (emptying the can). Some universal kits might come with lower quality hoses that need upgrading, as noted in customer reviews for some muge racing products. In very cold weather, there’s a slight possibility of condensation freezing in the can or hoses if the can is mounted far from the engine’s heat, but this is rare with properly designed baffled cans and usually only an issue in extreme conditions or with very long hose runs.
Q: What’s the difference between a vented and sealed oil catch can system?
A: A vented oil catch can system uses a breather filter on top of the can, allowing crankcase gases to vent directly into the atmosphere after passing through the catch can. A sealed oil catch can system recirculates the filtered air back into the engine’s intake. For most street-driven 5.7 Hemi vehicles, a sealed system is preferred as it maintains the vehicle’s emissions system as designed and prevents unfiltered gases from entering the environment. Vented systems are more common in racing applications where emissions are not a primary concern.
Protecting your 5.7 Hemi engine from the detrimental effects of oil vapor recirculation is a smart investment in its longevity and performance. By choosing one of the best oil catch cans for 5.7 Hemi from our expertly reviewed list, you’re not just buying an accessory; you’re safeguarding the heart of your vehicle. Remember to consider your specific vehicle model, driving habits, and budget, and always prioritize a quality baffled design for maximum effectiveness. Don’t wait for carbon buildup to impact your Hemi’s power and efficiency – take action today and keep your engine running clean and strong!
