Hey all, Was getting a slight leak from my drain plug lately and when I changed the oil this time I put a new copper gasket on my drain plug and am still getting the slightest leak. I can see it starting to show around the gasket again. None of the threads seemed to be crossed or over-tightened etc. Has anyone ever had an issue with this? Next oil change I'll try a new plug too, but don't want to drain my new oil. Also hoping it's not somehow the pan?
