I had recently purchased Toyota oil filters from Keithvibe, which included the drain plug gaskets (Toyota 90430-12028). They seem to be made of some type of soft composite material, and is apparently the older style gasket, as pictured:
However, my 2004 Vibe appears to have come with the newer type gasket (Toyota 90430-12031), which I have reused and never replaced. It appears to be a Teflon-coated metal washer, as pictured:
My question is, which washer should I use? The 90430-12028 composite gasket seems to have a history of being destroyed and leaking if overtightened. There is not much info on the 90430-12031 metal gasket failing or otherwise.
