I noticed last night a little pool of oil under my car. After jacking it up and looking both oil pan plugs are dripping very slightly. This is a 7 quart canton oil pan, only 3 years old. I cranked down and its tight, but looking at it it looks like my speed shop added a washer between the bolt and pan. I suspect this maybe an issue as it has never leaked before this. I'm going to change the oils this evening and remove the washer, does anyone recommend a special washer or some sort of sealant?
