Dug into the oil pan gasket project today. What an absolute P.I.T.A. There’s a cork gasket for this oil pan, but based on some threads here and the FSM it wasn’t necessarily used by Toyota after a shift to just using RTV. Judging by how messy the existing RTV gasket was, I doubt this was the factory seal. It took me ages with a putty knife, a rubber mallet and a torch (after plenty of other creative attempts) to pull it off. The FSM says to remove the sump piping and stiffener plate as well. That was a little easier. Cleaned / sanded / primed / painted the outside of the oil pan, cleaned up the inside, and cleaned up all my gasket surfaces and will hopefully put it all back together tomorrow, let it cure, and fill her back up Tuesday. I need to double check the new gasket against the actual pan, but planning on using it as opposed to RTV only. Cross your fingers for no more leaks!
