Hi. First poster here. I have a cylinder 8 misfire. Changed plugs. Swapped coils. New injectors. Sealed valley pan coolant leak. All cylinders have good compression 190 psi. Seems high though. Leak down good too. All above 95 with 100 psi applied. Losing coolant. Exhaust seems sweetish. 15 psi on coolant system leaks out slowly. Looked in 2,4,6,8 cylinders and they seem dry. When doing leak down on 8 the radiator level moves a little but no bubbles. Has anybody have any thoughts on this? Thanks
