Why My 2017 F350 6.7 Crankcase Filter Is Necessary
From my experience with the 2017 F350 6.7, the crankcase filter plays a crucial role in keeping the engine running smoothly. It helps trap harmful contaminants and oil vapors that escape from the crankcase, preventing them from re-entering the engine’s intake system. Without this filter, these impurities can build up and cause sludge or carbon deposits, which can seriously affect engine performance and longevity.
I’ve noticed that having a clean and functioning crankcase filter also helps maintain proper ventilation inside the engine. This reduces pressure buildup, which can otherwise lead to oil leaks or gasket failures. In short, the crankcase filter protects my investment by ensuring cleaner engine internals and preventing potential costly repairs down the road. For anyone who relies on their F350 for tough jobs, this small part is definitely necessary for reliable, long-term performance.
My Buying Guides on 2017 F350 6.7 Crankcase Filter
When I decided to replace the crankcase filter on my 2017 Ford F350 with the 6.7L Power Stroke engine, I quickly realized that choosing the right part requires some careful consideration. To help you out, I’m sharing my experience and tips on what to look for when buying a crankcase filter for this specific truck.
Why the Crankcase Filter Matters
The crankcase filter plays a vital role in keeping the engine clean by filtering out oil vapors and contaminants from the crankcase ventilation system. I learned that a good filter helps maintain engine performance and prolongs its lifespan. Using the wrong or a low-quality filter can cause blockages or allow harmful particles to enter the engine.
Compatibility with the 2017 F350 6.7L Power Stroke
First things first — I made sure the crankcase filter I chose was specifically designed for the 2017 F350 with the 6.7L diesel engine. Not all filters fit properly or meet the specifications for this model. I checked the part number and cross-referenced it with my truck’s VIN to be certain of compatibility.
OEM vs. Aftermarket Filters
I considered whether to buy an OEM (Original Equipment Manufacturer) filter or an aftermarket option. OEM filters are made by Ford or their authorized suppliers, ensuring perfect fit and quality. Aftermarket filters can be less expensive but vary widely in quality. I read user reviews and sought filters from reputable brands to avoid any performance issues.
Filter Material and Build Quality
The filter media and construction really matter. I looked for filters with durable materials that can withstand high temperatures and resist clogging. A well-built filter ensures consistent airflow and effective filtration over time.
Ease of Installation
Since I planned to replace the filter myself, I chose one that came with clear instructions and all necessary components for installation. Some filters come as complete kits, which made the process easier and saved me time.
Price vs. Value
While shopping, I balanced cost and quality. I didn’t want to overspend but also didn’t want to sacrifice engine protection. In my experience, paying a bit more for a trusted brand and proven filter performance is worth it in the long run.
Where to Buy
I found that purchasing from authorized Ford dealerships, trusted auto parts stores, or reputable online retailers gave me confidence in product authenticity and return policies. Avoiding unknown sellers helped me steer clear of counterfeit or subpar filters.
Final Thoughts
Replacing the crankcase filter on my 2017 F350 6.7L was straightforward once I knew what to look for. Prioritizing compatibility, quality, and brand reputation made the process smooth and ensured my truck’s engine stayed well protected. I hope my guide helps you find the right crankcase filter for your F350!
