- For this vehicle, aftermarket is the only practical option. Brands like Standard Ignition (SMP) are a reliable choice.
- Replacement is a simple, low-cost DIY job that can prevent catastrophic engine failure.
- No specific recalls or TSBs exist for this part on the Dodge 880, making owner vigilance key.
Is Your Oil Light On or Flickering?
For a classic like the 1962-1965 Dodge 880, the oil pressure warning light is your engine's main line of defense. When this light comes on, you must take it seriously. However, the switch that controls this light can fail, leading to false alarms or no warning at all.
Common Failure Symptoms
A bad oil pressure switch has a few common symptoms. Recognizing them can save you from both unnecessary panic and catastrophic engine failure.
- Oil Light Stays On: If the oil light is on but the engine sounds normal and the oil level is full, the switch might be stuck in the 'on' position.
- Flickering Oil Light: A light that flickers, especially at idle or when the engine is hot, can indicate a failing switch or borderline low oil pressure.
- Oil Leaks: The switch itself can develop leaks over time. You may see oil residue on the switch or drips on the ground from the back of the engine.
First, Verify the Pressure
Before replacing the switch, it's wise to check the actual oil pressure with a mechanical gauge. This involves temporarily removing the switch and threading in a gauge to get a true reading. This step confirms whether you have a simple sensor problem or a more serious internal engine issue. On these Mopar engines, the switch is typically located at the rear of the engine block, near the distributor.
Choosing the Right Aftermarket Switch
Finding a new original Mopar part for a 1960s vehicle is nearly impossible. The aftermarket is your only realistic option. Quality can vary, so it's important to choose a reputable brand.
Brand Quality Tiers
- Tier 1 (Established Brands): Standard Ignition (SMP) is a well-known, established brand with decades of experience. They manufacture many of their own parts and are generally considered a reliable choice for classic vehicles. While individual reviews can be mixed, they are a go-to for many mechanics.
- Tier 2 (OE & Transmission Specialists): Rostra Powertrain is a known supplier of electronic components, including for original equipment manufacturers. They have a reputation for quality in transmission parts, which suggests a good standard of manufacturing that likely extends to their sensors and switches.
- Tier 3 (Budget/Private Label): Brands like Global Parts often fall into the budget category. Information on their quality for this specific type of part is scarce and can be mixed with other companies of the same name. These parts may be a good value, but their long-term durability is less certain compared to more established names.
Pro Tip: When replacing the switch, apply a small amount of thread sealant to the new switch's threads to prevent leaks, unless it comes with sealant already applied. Be careful not to overtighten it.
Cost of a New Oil Pressure Switch
Replacing the oil pressure switch is one of the most affordable repairs you can make. The cost comes down to the part itself and whether you do the work yourself.
