What is the solution for oil accumulation in the throttle of the new Mondeo?
2 Answers
To address oil accumulation in the throttle of the new Mondeo, it is necessary to replace the throttle. Below is relevant information about the throttle: 1. Working Principle: The throttle is a controllable valve that regulates the entry of air into the engine. Once the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then ignites to perform work. 2. Location: The throttle is connected to the air filter at the top and the engine block at the bottom, often referred to as the throat of the car engine. 3. Maintenance: The throttle requires periodic replacement, with the interval primarily determined by factors such as the quality of the air filter, the quality of the engine oil, and the driving conditions of the vehicle. 4. Types: There are four types of electronic throttles: electro-hydraulic, linear solenoid, stepper motor, and DC servo motor.
I also encountered oil accumulation in the throttle body with my previous new Mondeo. It shook badly at idle, and acceleration wasn't smooth at all. DIY cleaning is super easy—I just sprayed some throttle body cleaner. First, turn off the engine, remove the intake pipe, and carefully spray to clean off carbon deposits and oil stains. Move slowly to avoid damaging the sensors. This process takes about 10 minutes, and the car runs smoothly right after starting. Actually, oil accumulation is mainly due to the aging PCV valve, causing oil vapor to flow back into the intake. So, I regularly check that little valve and replace it for just a few bucks to fix the issue. I recommend cleaning the throttle body every two years and using good-quality engine oil to significantly reduce problems. Proper maintenance extends engine life—don’t wait for major failures to repair.
