Thanks for these. I do think I likely need to redo the valve seals or the piston rings because the car loses about a quart of oil every 3000-4000 miles. Some of that is leaking out, but I am willing to bet that after 266,000 miles, some is getting burned. Seals and rings have never been replaced.

But here is the thing... the CAT dtc has not returned since a few weeks ago. And it showed up after about 60 miles continuous (some P&G) driving. If oil is the culprit it would have to have been leaking pretty bad and given the conditions of the failure, it would probably have recurred sooner, rather than later, no?
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
