I am preparing a L28Et for installation in my 240Z. The motor has a factory oil cooler and I would like to block it off for now to simplify the installation. I bought adapters and AN blockoff caps to replace the factory banjo bolts. It just occurred to me that I don't know if the motor need to flow oil through the oil cooler fittings for proper oiling. Does anyone know if it is safe to block the cooler lines?
