Problems like spark plug dislodgement can cause additional engine complications, along with loose gaskets that require securing. Engine overheating poses a significant risk, potentially resulting in car fires or explosions. Keep an eye out for excessive oil consumption, necessitating prompt oil changes. Replace the air filter every 15,000 to 30,000 miles, the coolant every 60,000 miles, and the spark plugs every 100,000 miles unless they are copper, which should be changed every 30,000 miles.
