I found some oil under my car following an oil change at my local shop. I wiped the pan down as best I could assuming, it was residual from the change. Checking again this morning I found more oil under the car. I’m planning to take this back tomorrow however, looking at the drain plug. Does this appear that they used a regular washer and a crush washer?
Before you do a thing!! Check the HEX of the plug for any identifications. Some LT1 drain plugs are 1/2-20, some are M12-1.75 the sealing required is I believe different.
**** I believe the correct seal if it's Metric was serviced with the drain plug.
does this look correct?
