Honda Accord: F23A Piston Ring Oil Consumption
F23A Piston Ring Oil Consumption is a common engine fault on the Honda Accord on the 1997–2002 cars, and we rate it major. Putting it right costs $1,800 to $4,500 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 55 documented faults on the Honda Accord.

What goes wrong
The F23A 2.3-litre four-cylinder fitted to CF/CL Accords is documented to develop piston ring wear that allows engine oil to enter the combustion chamber. Consumption rates of 1 litre per 1,000–2,000 km are commonly reported on engines above 150,000 km. The failure is progressive: worn rings allow blow-by gases to contaminate the oil, accelerating wear. Prolonged neglect causes bore glazing and fouled catalytic converters. Honda New Zealand service records from this era reflect this as a known consumable failure on high-mileage examples.
What you would notice
- Blue-tinged exhaust smoke on start-up or under hard acceleration
- Oil level dropping 1 litre or more between 2,000–3,000 km service intervals
- Spark plugs showing black oily carbon deposits
- Persistent oily residue around the PCV valve and intake
How to check it
Where to look. Engine internals — piston rings, cylinder bores
Check the oil level and ask when it was last topped up.
Start from cold and watch the exhaust for blue smoke during the first minute of running.
Inspect spark plugs for oil fouling. wet with oil added) isolates ring wear from valve seal failure.
Remove the oil filler cap with engine running — excessive crankcase pressure (puffing smoke from the cap) confirms ring blow-by.
If a workshop inspection is possible: A compression test (dry vs.
What it costs to put right
$1,800 to $4,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “How often does the engine need oil top-ups and approximately how much between services?”
- “Has the engine ever been rebuilt or had piston rings replaced?”
- “Does the exhaust produce any blue or grey smoke when first started?”

Honda Accord buyer questions
Is f23a piston ring oil consumption serious on a Honda Accord?
We rate it major and common on the Honda Accord. The F23A 2.3-litre four-cylinder fitted to CF/CL Accords is documented to develop piston ring wear that allows engine oil to enter the combustion chamber. Consumption rates of 1 litre per 1,000–2,000 km are commonly reported on engines above 150,000 km.

How much does it cost to fix on a Honda Accord?
$1,800 to $4,500 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.
Which Honda Accord years are affected?
Our research records this fault on the 1997–2002 Honda Accord. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
How do I check for it before I buy?
