I have a 2008 Silverado w/ 5.3. Using Fram Ultra and M1 5W-30. I have some slight seepage from my drain plug. I've torqued it to spec and even replaced the entire plug and rubber o-ring but it's still leaking. Maybe 1 or two drops of oil in the garage a night. I was thinking about replacing the plug with one from the autoparts store and using a different gasket. The one that keeps coming up for my truck is the Needa plastic/nylon blue washer. Is that a reliable gasket and any issues with using a washer/gasket like that? https://shop.advanceautoparts.com/p...
It's the bluish/gray one on the top right in the picture.
Could I use teflon tape too? Or some sort or thread sealer?
