Disadvantages of the Honda G25A engine
- There are no questions about the reliability of the motor, but there are problems with the service and spare parts;
- Most owners are bothered by frequent oil leaks from gaskets and seals;
- The timing belt runs about 100 thousand km, and when it breaks, the valve bends in 100% of cases;
- The reason for the floating engine speed is usually a dirty throttle or idle valve;
- There are no hydraulic lifters and valve clearances need to be adjusted every 40,000 km.
