How to Solve Oil Burning Issue in Sixth-Generation Camry?
2 Answers
Confirm whether carbon deposits are causing the piston rings to stick. You can replace them without disassembling the cylinder. If replacing the valve stem seals can solve the oil burning issue, this is a cost-effective method. Check if the cylinder walls and pistons are severely worn. If the gap is too large, an engine overhaul is required, which will significantly reduce the car's value after the repair.
My sixth-generation Camry also experienced oil burning, which I treated as an issue common to older cars. First, I monitored the oil consumption—burning more than one liter per 1,000 kilometers is a red flag, often caused by worn piston rings or aging valve seals. I took it to a professional shop for diagnostics, such as compression and leak-down tests, to pinpoint the problem. The repair approach depends on severity: minor cases may require replacing seals or using oil additives for temporary control; severe cases demand an engine overhaul with new piston rings—costly but safer. For maintenance, I switched to slightly thicker oil like 10W-40 and avoided aggressive high-speed acceleration to reduce heat-induced wear. Ignoring oil burning leads to blue exhaust smoke, catalytic converter damage, or even engine failure. After repairs, the car runs smoothly and gives me peace of mind.
