    I hope that the o ring is your leak. It was on mine.
    Since the oil pan is glued on, that seems unlikely culprit.

    Tuff Country lift, headers, new Jeep seats, custom made console, many more.
    I think that the figure 8 O-ring is the problem. The leak got worse after moving the adapter around and reassembling it without replacing the O-ring. I am fairly sure that the new one will fix it. I mean, that O-ring is 21 years old and then I disturbed it by rotating it.

    I think at 21 years, you got your monies worth.

    Hello Diablo 675.
    I need to understand more on how to get to the last bolt. did you completely loosen the ac compressor (not the hoses) and move it out of the way of the one bolt that is behind the ac compressor?

    hello shifty - yeah started this double oring gasket replacement based off this video. The sequoia must be slightly different than the Tundra. there is a bot behind the ac compressor on my Tundra configuration.

    Thanks.

    Anyone know how much more involved that makes this compared to the above video? I was just told my truck has this same issue.

    I talked with Diablo675 again and it will take some doing but he has mentioned a couple of times to me now that it is well worth it. I have 285,000k on my 06 DC & just changed the valve cover gaskets & that did not completely solve the oil leak problem. I can see and am 99% sure it is this little figure 8 o-ring @ the oil filter adapter.
    I'm going to tackle mine in the next month and will keep you posted.
