🔊GDI engines in Volkswagen GTIs have a tendency to carbon up, resulting in engine noise.
🛢️Lower tension piston rings in modern cars lead to better gas mileage but also cause oil burning and engine noise.
⚙️Carbon buildup inside the engine can be cleaned using oil additives and running the engine at a fast idle.
🔧Low tension piston rings can be a common issue in GM V8 engines, causing oil burning.
🚗Clogged catalytic converters can also cause engine performance issues and fuel trim problems.
Why does the Volkswagen GTI engine make so much noise?
—The carbon buildup in GDI engines and low tension piston rings are the main causes of engine noise.
What are the potential consequences of carbon buildup in the engine?
—Carbon buildup can lead to increased engine noise, burning oil, and decreased performance.
Can oil additives help clean the engine and reduce noise?
—Yes, oil additives designed to remove carbon buildup can be effective in reducing engine noise.
What other engines commonly experience low tension piston ring issues?
—GM V8 engines are known to have low tension piston rings, leading to oil burning and engine noise.
What other factors can affect engine performance and fuel trim?
—Clogged catalytic converters can restrict exhaust flow and cause fuel trim problems.
