|April 19, 2007 - The oil pan is sealed with a big bead of black silicone.|
It's a little unnerving, because if you don't get it all sealed then you get the pleasure of pulling the engine out again. Yuk.
This silicone is "The Right Stuff", the favorite at Flyin' Miata. The black color also looks more professional than orange or grey, as it unavoidably squeezes out of the seams.
