He clearly stated he is running Mobil 1 0-40. If it was mine I would quickly resolve that problem by going back to the previous engine oil that kept the lifters pumped. You can't have them running like a thrashing machine. I don't have hydraulic lifters and I changed to Mobil1 5-40 a couple of days ago. I really can't believe the wonderful improvement that made on that 617. It starts like a gasser now, and is so smooth and quiet I can't hardly stand it. I do so the oil pressure is down a bit quicker at low engine speeds.
