I have two (2) Camry's...both with the 4-cylinder engine. I change oil in both of them ~ 2x per year. I use the Toyota oil drain plug gasket pictured below and torque both drain plugs to 18 ft-lbs per Toyota spec. Over the past 2 years, I've noticed that both drain plugs are finger tight at best when I change the oil. I've noticed that the coating or whatever is on both sides of these aluminum washers disintegrates...mostly on the side of the gasket that is in touch with the oil pan. FWIW both oil pans are metal. The drain plugs are both the original and are perfect. You can hand tighten both bolts snug and then tighten with the torque wrench. FWIW I have two different torque wrenches I've used to make sure there is not a problem with the amount of torque applied. I have in the past bought packets of washers from a Toyota online parts dealer and really haven't had an issue. I went to my local dealer and bought a few washers for the most recent change to see if I would get a different result....same problem. Within a week both drain plugs have loosened to where you need to tighten the bolts another 1/4 turn or more. Thankfully neither drain plug has completely come out. Generally they seem to about one to two turns to being hand tight.
Question...has any one experienced this problem using TOYOTA drain plug gaskets? For reference here is a picture of the gasket and the Toyota p/n.
