I replaced a catalytic converter and 2 O2 sensors a few months ago. Check engine light came on. Oil was pooling into the catalytic converter from the engine. Technician checked pistons. Said there was unusual wear and oil was coming in through the pistons.
My Volvo XC70 has had a sudden and significant increase in oil consumption. I believe this is due to the pistons which Volvo is now acknowledging. They refuse to issue a recall or to repair my very well maintained vehicle. Continue operation requires up to 2 quarts of oil every 500 miles! It also presents an ongoing risk of sudden engine malfunction and dangerous stoppage, I have all my records which shows my car has been maintained and the cause is faulty pistons. Volvo must be held accountable.
