How to Solve the Oil Burning Issue in Peugeot 408?
2 Answers
The solutions for oil burning in Peugeot 408 are: 1. If the piston rings are stuck due to carbon deposits in the cylinder, cleaning the piston rings will suffice; 2. If the valve stem seals are damaged, replacing the valve stem seals can solve the issue, and this can be done without disassembling the cylinder; 3. If the cylinder walls and pistons are severely worn, then an engine overhaul is necessary. Taking the 2020 Peugeot 408 as an example, its body structure is a four-door, five-seater sedan, with body dimensions of length 4750mm, width 1820mm, height 1488mm, a wheelbase of 2730mm, a fuel tank capacity of 53 liters, a trunk capacity of 455 liters, and a curb weight of 1325kg.
As a veteran driver with over 20 years of experience, I've seen plenty of cases of Peugeot 408 burning oil. It's usually caused by engine aging, such as worn piston rings or failed valve stem seals, which allow oil to enter the combustion chamber and burn. A rapid drop in oil level on the dipstick is a clear sign. You can start by checking the PCV valve yourself – if it's clogged, it can accelerate oil consumption. Trying an additive to clean carbon deposits might provide temporary relief. But don't delay too long, otherwise the engine could suffer more damage and repairs will cost more. I recommend finding a trustworthy repair shop for proper diagnosis, and don't immediately believe any major overhaul suggestions. Regular full synthetic oil changes and avoiding sudden acceleration can help prevent this issue.
