Things are finally starting to come together. The charge pipe has been painted to prevent corrosion and the BOV has been recirculated to the new air intake that draws air from outside the engine bay. Also, the valve cover vents have been rerouted to the new oil catch can and a Nissan UK oil cooler has been added to the block. I found it as the local salvage yard. This will be changed into a dual stage oil cooler in the future.
