Also note that there are MANY SC's and STB's covering the Packard V8 oil consumption. A few retracting earlier service procedures. There is one STB or SC that came out rather late. It indicates (paraphrasing) that "if all else fails then replace the piston rings".

Read those STB's and SC's with a vigilant and suspicious eye. My analysis on them is that PMCC was hedging. The problem is piston rings. PMCC was merely trying to avoid that costly problem by jerking the customer around with cheaper and easier bandaid type procedures such as drying up the overhead to bare necessary oil delivery.
