What is this hole in bottom of 4tec block?
There is a small, approx 1/2 inch hole in the bottom of my engine block that appears to have a press fit plastic, flanged sleeve but it doesn't seem to connect to the oil pan in any way. Anybody know what it is? The hole seems to be dead end in the block. In the first pic it is visible within the box area shaped by the main bearing braces.
