What is the solution for oil accumulation in the throttle of the new Mondeo?
4 Answers
For the new Mondeo, oil accumulation in the throttle requires replacement of the throttle body. Here is relevant information about the throttle: Working principle: The throttle is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture for combustion and power generation. Location: The throttle connects to the air filter at the top and the engine block at the bottom, serving as the throat of the automobile engine. Maintenance: The throttle requires periodic replacement, with the interval mainly determined by factors such as air filter quality, oil quality, and driving conditions. Types: Electronic throttles come in four varieties: electro-hydraulic, linear electromagnetic, stepper motor, and DC servo motor.
I've driven a Ford for ten years, and it's quite common to encounter oil accumulation in the throttle body of the new Mondeo, mainly caused by a faulty oil separator leading to oil backflow into the throttle body. The solution is to first remove the throttle body, clean the sludge and carbon deposits with a specialized cleaner, and wipe it down with an old towel to ensure no residue remains. I've done this myself multiple times, and it takes about an hour to complete. Then, check if the PCV system is functioning properly and replace the separator with a new one to prevent recurrence. Using full synthetic oil in daily driving can reduce oil buildup, and adding a fuel additive every 5,000 kilometers is also effective. Regularly cleaning the air filter is key to preventing dust from entering and worsening the issue. Act promptly when the engine idles unevenly—don't wait until major engine problems arise. It saves both money and hassle.
I have a deep understanding of automotive intake systems. Oil accumulation in the Mondeo's throttle body is often caused by PCV valve failure or intake pipe leaks, where oil vapor builds up and forms blockages. The solution is to thoroughly clean the inside of the throttle body by evenly spraying a bottle of cleaner, letting it sit for a few minutes, and then wiping it dry. Next, check the condition of the oil separator; replace it if there's any leakage. For a DIY approach, prepare a wrench and gloves—it can be done in about half an hour. I recommend driving at higher RPMs on highways to help burn off carbon deposits. When changing the oil, opt for high-quality brands and pair it with regular air filter replacements. This fundamentally prevents oil accumulation issues and ensures smoother engine operation.
Having driven the Mondeo for so many years, I've learned that the throttle body oil accumulation issue must be addressed promptly to avoid affecting driving safety. The best solution is to have the throttle body cleaned at a professional repair shop, which only costs a few hundred yuan. The technician will check if the PCV system is functioning properly and replace any failed components. I personally inspect it every three months to remove oil buildup. During maintenance, I use the recommended cleaner to spray and wash it once, keeping the intake clean. Pay attention to any shaking signs at idle speed, and stop for repairs if any abnormalities are detected. With this preventive approach, I can drive with peace of mind.
