I agree. The fundamental problem wasn't fixed, merely forestalled. We can even ballpark when it should crop up again. It took 240k miles for the first cat to fail. Integrating my rate of oil loss, if it all burned then I should expect the new one to fail in around 80k miles. But the oil catch can has significantly reduced the burnt fraction, I'd say by at least half. So I'm probably looking at another failure in 160k-ish miles.
I'm 40k miles into the new one, and looking at another 120k miles before I expect another cat problem. Realistically, the rest of the car may not survive that long. I'm already seeing the harbingers of other major problems (radiator, timing chain, transmission, etc.) So there's a good chance something else is going to catastrophically fail before the cat does. I mean... the optimal scenario is to try to get them to all fail at the same time, right?
