I changed the oil today on my 2011 FJ Cruiser, replaced both rubber gaskets on the housing and used the stock Toyota filter. I tightened it to spec but noticed it leaking slowly between where the screw on housing mates against the metal mounting unit. I tried to tighten it a bit more which did help, but there is still some slight seepage along the mating joint. The only thing I can think of is there is debris on the mating surfaces in the joint itself or the large rubber gasket is not seated properly. Guess I need to remove the housing and see what I find, anyone else have this happen? Thoughts? Can I drain the filter from the bottom as if I were changing it and remove the screw-off housing without losing all of the new oil I poured in today?
