I used the Toyota fipg and felt like it all went in well but a week later still leaking more than I like.
It might be leaking from behind the timing plate.
Or possibly the two lower bolts in the TC. They thread into the front main bearing cap I believe providing a direct path for engine oil to escape if not sealed properly. FSM calls for sealer on them when installing for this reason. I don't think I cleaned out the bolt holes enough of oil when I put mine back in and the sealer never really set up right. Mine seeps a little from these bolts I think. As @cps432 mentions, the plate seal can leak as well. I didn't replace mine. Hard to tell where the oil is coming from on that seal sandwich in that area. I installed my TC gasket dry FWIW.
