fredoly I am confused also. The pressure line comming from the block (where the oil pressure guage is connected) is going to another T that connects to your head near the coil. This line is doing nothing but by passing the filter. Why is this T nessary at the filter? It would seem that this would lower your oil pressure. That is why the orfice is in the filter, to keep the oil pressure up. All of the filter cans that I have seen have had only an in and a out line without any T's involved except at the oil pressure guage line. If it were mine I would remove that T at the filter and see if it increased my oil pressure. My 02.
