2019 Ram 6.7 Cummins Oil Filter Part Number

Maintaining your 2019 Ram 6.7 Cummins diesel engine requires diligence, and one of the most crucial aspects is regular oil and filter changes. Using the correct oil filter is paramount for optimal engine health and longevity. Let's delve into the correct oil filter part number, common issues that arise from using incorrect filters, and troubleshooting tips for your 6.7 Cummins.

The Correct Oil Filter Part Number for Your 2019 Ram 6.7 Cummins

The recommended oil filter for a 2019 Ram 6.7 Cummins is typically Mopar MO-285 (68197867AA). However, always double-check your vehicle's owner's manual or consult with a trusted Ram dealership to confirm compatibility. While aftermarket alternatives exist, sticking with the Mopar filter ensures proper fit, filtration efficiency, and adherence to the engine's original specifications. Using a generic filter may seem like a cost-saving measure, but it can lead to significant engine problems down the line. For instance, some owners report issues with aftermarket filters collapsing internally, restricting oil flow.

Common Problems from Using the Wrong Oil Filter

Using an incorrect oil filter can manifest in several ways. Here are some common symptoms and their potential causes:

• Low Oil Pressure: This is perhaps the most serious consequence. An incorrect filter may have inadequate flow rate or may become clogged prematurely. This restriction can lead to reduced oil pressure, starving critical engine components of lubrication. The symptom? The oil pressure gauge in your instrument cluster will read abnormally low, or the "Check Engine" light might illuminate with codes related to low oil pressure. Think of it like trying to drink through a straw that's been pinched shut – the effort is there, but the flow is severely restricted.
• Engine Knocking or Ticking: Insufficient lubrication, caused by a poorly functioning or incorrectly sized filter, can result in engine knocking or ticking noises. These sounds indicate metal-on-metal contact within the engine, a sign of serious damage. Similar symptoms can also occur in gasoline engines, like a 2015 Ford F-150 experiencing knocking due to insufficient oil flow.
• Premature Engine Wear: Even if the engine doesn't exhibit immediate symptoms like knocking, a subpar oil filter won't effectively remove contaminants from the oil. This leads to increased wear on engine components like bearings, pistons, and camshafts. Over time, this accelerates engine degradation and reduces its lifespan.
• Oil Leaks: An improperly sized or poorly sealed filter can cause oil leaks. The filter housing might not seat correctly against the engine block, or the filter's seal might be defective. This not only creates a mess but also contributes to low oil levels, exacerbating lubrication problems. Some owners mistakenly attribute these leaks to the oil drain plug, but the filter seal is a common culprit.
• Check Engine Light: The engine's computer monitors various parameters, including oil pressure and temperature. A faulty or incorrect oil filter can trigger the "Check Engine" light, storing diagnostic trouble codes (DTCs) related to oil pressure or flow.

Troubleshooting and Solutions

If you suspect an issue with your oil filter, here's a step-by-step approach to troubleshooting:

1. Verify the Part Number: Double-check that the installed oil filter matches the recommended part number for your 2019 Ram 6.7 Cummins (Mopar MO-285 or 68197867AA).
2. Inspect for Leaks: Carefully examine the oil filter and its surrounding area for any signs of oil leaks. Check the filter's seal and the engine block mating surface.
3. Check Oil Pressure: Monitor the oil pressure gauge while the engine is running. If it's consistently low, even after replacing the filter with the correct one, further investigation is needed.
4. Listen for Unusual Noises: Pay attention to any unusual engine noises, such as knocking or ticking. These noises could indicate engine damage due to insufficient lubrication.
5. Scan for Diagnostic Trouble Codes (DTCs): Use an OBD-II scanner to check for any stored diagnostic trouble codes. Codes related to oil pressure or flow can provide valuable clues.

Solutions:

• Replace the Oil Filter: If the filter is incorrect, damaged, or suspected of being faulty, replace it immediately with the correct Mopar MO-285 filter.
• Check Oil Level: Ensure the engine oil level is within the recommended range. Low oil levels can exacerbate lubrication problems.
• Inspect Oil Pressure Sensor: A faulty oil pressure sensor can provide inaccurate readings. Consider testing or replacing the sensor if necessary.
• Consult a Mechanic: If you're unsure about the cause of the problem or lack the necessary tools and expertise, consult a qualified mechanic. They can perform a thorough inspection and diagnose the issue accurately.
• Oil Analysis: Consider getting an oil analysis performed. This can reveal valuable information about the condition of your engine and identify potential issues early on. Oil analysis can detect the presence of metal particles, fuel dilution, or other contaminants that could indicate engine wear or damage.

Real-World Examples

Consider a situation where a 2019 Ram 6.7 Cummins owner uses a cheaper, aftermarket oil filter. After a few thousand miles, the owner notices a persistent ticking sound coming from the engine, especially when cold. Upon inspection, the oil pressure is found to be slightly lower than normal. Replacing the aftermarket filter with the correct Mopar MO-285 filter resolves the ticking sound and restores normal oil pressure. This illustrates the importance of using the correct, high-quality filter. Contrast this with a mechanic who always uses Mopar filters for his customer's Cummins engines and regularly checks their oil, resulting in engines that easily surpass 300,000 miles with no major issues.

Keeping Your Car in Top Condition

Regular maintenance is key to prolonging the life of your 2019 Ram 6.7 Cummins. Here are some tips:

• Follow the Recommended Maintenance Schedule: Adhere to the maintenance schedule outlined in your vehicle's owner's manual. This includes regular oil and filter changes, as well as other essential services.
• Use High-Quality Oil: Choose a high-quality synthetic diesel engine oil that meets the specifications recommended by Ram.
• Check Fluid Levels Regularly: Monitor the levels of all essential fluids, including engine oil, coolant, transmission fluid, and power steering fluid.
• Inspect Belts and Hoses: Regularly inspect belts and hoses for cracks, wear, and leaks. Replace them as needed.
• Address Issues Promptly: Don't ignore warning signs or unusual noises. Address any issues promptly to prevent them from escalating into more serious problems.
• Keep Accurate Records: Maintain detailed records of all maintenance and repairs. This will help you track your vehicle's history and identify any recurring problems.

By following these guidelines, you can ensure the longevity and reliability of your 2019 Ram 6.7 Cummins diesel engine. Remember, preventative maintenance is always more cost-effective than repairing major engine damage caused by neglect or using incorrect parts.
