Before today, I have always had mechanics change the oil on my car. Today was the first time that I have ever changed the oil on the Contour.
When I removed the oil pan drain plug, I noticed that the drain plug had rubber around the bottom edge of the bolt head. Sort of like an o-ring/gasket built onto the bolt.
Is the OEM drain plug supposed to have rubber on the end of the bolt head? Or is this a drain plug that was replaced by some mechanic?
I also noticed a plastic washer between the drain plug and oil pan.
Is this normal? Should there be a washer there?
It seems odd to have both a rubber piece on the drain plug AND a plastic washer.
