I took my car to the dealer for its 70Km oil change and maintenance. The service person claimed that upon removal of the OIL PAN BOLT the stint(Coil) that goes around the inside of the oil pan grooves, cam out with the bolt.
And.. my options were to replace the oil pan case for $250dls or send the oil pan case to the machine shop and have them rethread the case.
So I don't want an oil pan with another stint in it, so I told them to sent it to the machine shop to rethread the case.
In my 30 years of doing oil changes I had never seen a oil pan with a stint in the oil pan that formed the thread. WTF!!!
