What are the solutions for oil accumulation in the throttle of the new Mondeo?

When oil accumulates in the throttle of the new Mondeo, it can be resolved by replacing the throttle. Below is a detailed introduction about the automotive throttle: 1. Overview: The throttle is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter at the top and the engine block at the bottom, it is referred to as the throat of the car engine. 2. Classification: Throttles are divided into two types: traditional cable-operated and electronic. The traditional engine throttle operates through a cable (flexible steel wire) or linkage rod, with one end connected to the accelerator pedal and the other to the throttle linkage plate. The electronic throttle primarily uses a throttle position sensor to control the opening angle of the throttle based on the engine's power requirements, thereby adjusting the amount of air intake.
I've been driving the new Mondeo for a year now, and oil accumulation in the throttle body is quite common, usually caused by a clogged PCV system or aging cylinder seals. To deal with it, I usually clean the throttle body myself first: remove the intake pipe, spray and clean it with a specialized spray, then wipe it dry and reassemble it, costing just a few dozen yuan. If oil still accumulates after cleaning, then it's necessary to check the crankcase ventilation valve or pipes for leaks and replace parts if needed. Don't delay, otherwise, you'll face unstable idling, soaring fuel consumption, and more serious engine damage. Now, I check the oil dipstick monthly and learn some basic knowledge when cleaning oil stains. I also try to drive more long-distance trips to avoid frequent cold starts on short trips, which has proven to be quite effective in prevention.
As a new Mondeo owner, I was quite anxious when encountering oil accumulation in the throttle body, with severe idle shaking. After checking the manual, the main solutions are cleaning and inspection: buy a cleaning spray and do it yourself, wait a few minutes after spraying, then reset the ECU. If the problem persists, it might be due to a failed PCV valve or fuel line leakage, which can be fixed at a repair shop by simply replacing parts for a few hundred dollars. Don't ignore it; excessive oil accumulation can lead to burning oil, and engine repairs are much more expensive. I usually pay attention to using full synthetic oil to reduce deposits. If on a tight budget, DIY is a cost-effective and reassuring option.
