One of the most common engine problems in Toyota vehicles, especially in older Camrys and Avalons, is oil sludge buildup. This happens when oil isn’t changed frequently enough, or poor-quality oil is used. Over time, this sludge can block oil passages, restricting flow to critical engine components and leading to overheating or engine failure. Regular oil changes using Toyota-approved synthetic oil can prevent this from becoming a costly issue.
High-mileage Toyota Corollas and other four-cylinder engines may experience head gasket leaks. A blown head gasket can cause coolant to leak into the combustion chamber, which leads to overheating, white exhaust smoke, and engine misfires. If caught early, this repair is manageable, but prolonged driving can cause irreversible engine damage.
While many Toyotas use timing chains instead of belts—reducing the need for scheduled replacement—chains can stretch over time, especially if the engine is under-lubricated. A rattling noise on startup could indicate a failing timing chain tensioner or guide. Ignoring these symptoms can result in poor engine timing and degraded performance.
