Here is the bottom of the engine as I needed to flip it over to surface the oil pan mating surface. I spent some quality time with the right angle grinder with a 3M brand 2" scotch type disc making it machine smooth and clean. Squeeze some Toyota gasket compound on one side and they will never some apart. That stuff is even more gooey and sticky than Permatex RTV Black!
Here is the first alloy oil pan that catches the oil from the blocks perimeter and directs it down toward the second oil pan. Obviously this is a 1UZ-FE front sump, first oil pan.
