The Chevy Malibu is equipped with a timing chain on the engine as a standard feature, which I believe is better than a timing belt because it does not require replacement. The costliest service for a car is typically replacing a timing belt, recommended every 60,000 to 100,000 miles, whereas a timing chain should only need replacement every 300,000 miles. It is still important to inspect the chain annually to ensure it is secure and clean to prevent potential failures.
The latest editions of the Chevy Malibu come equipped with a timing chain instead of a timing belt.
What leads to oil buildup in the area where you insert the spark plugs?
The issue could be the valve cover gaskets failing, resulting in oil seeping into the spark plug holes. This is a simple and affordable repair that can be done by someone with limited experience in cars at no cost.
