Have an 8BA with "95% Oil Flow Modification. This is where the oil galley is tapped at top rear of block and a remote filter is installed. I have about 30 - 35 Lbs of oil pressure at start up. With engine warm and at idle, oil pressure is at zero. At cruising rpm oil pressure is about 15 Lbs. I have about 2000 miles on engine since rebuild with no issues. This is with a melling oil pump, not a high volume pump. Called H&H and they don't like this mod. I was told to restrict the oil flow to the filter to keep oil in engine longer and at higher pressure. I was also told a high volume pump was not necessary and that it would make no difference. Using Bred Penn 10-40 oil. Is this something I even need to worry about? Would switching to a straight weight oil make a difference? Any advice would be greatly appreciated!
