What is the name of the flare fitting on the front of the block, I am referring to the port which supplies oil to the cyl head.
It is a 90 deg fitting with 3/8 npt on the end that threads into the oil gallery on the front of the block.
The threads for the line fitting are damaged,
So I will have to source a new fitting, thing is I don’t know for sure what the thread for the line end is called ??
