There is a port on my engine that looks like it should have a hose connected to it.
The engine is a B21FT, the port is located low on the block towards the rear on the left side, underneath the turbo. It looks about 1" in diameter and sticks out about 1 1/2" It looks like it should have a hose or something on it.
Does anyone know what this is for, and where does the other end connect to ???
P.S. Thanks to everyone for the help with the oil pressure gauge issue- problem solved for 75 cents worth of wire and an hour of my time.
