Sometime you do everything right, and still things break. Short of the root-cause analysis common to airplane accident investigations (we traced the metal used in the #1 bearing to a mine in Wyoming, where the guy driving the ore truck was not properly certified...) you may never know why it failed. Or you may find the supply line is clogged, despite using very good oil and otherwise treating the engine right.
It would be comforting to think that with regular maintenance, we'd never have an oil-related failure. But some people who don't smoke, don't drink, and exercise regularly drop dead of heart attacks, and others that are the poster child for bad behavior last well beyond all expectations. Same with cars. Doing the right thing can only help, but things still break.
Mr. Roscoe may be right, but nobody ever sends him good turbos. Like the coroner said 'all I see are dead people', and that must color your outlook.
If the oil line needs replacement every 50K miles, I would expect that if it wasn't done, by 100K miles, a statistically significant number of turbos would have packed up. And by 150K miles, most turbos would be in a pile behind the shop. But I've run three turbos over 150K miles, all on the original oil lines and turbos. Maybe I've been incredibly lucky.
My feeling on oil related failures is that short of never changing the oil (why should I put any in? I never took any out!), most oil related failures occur a very long time after the neglect. Long oil change intervals with Dari-Mart's Best Oil at 10K and 20K miles don't show up at 25K - they show up at 120K. Oil changes and other maintenance like that aren't for now, but for 4, 8 or 10 years from now. So it could be left at the feet of the PO.
Or you could have had a manufacturing defect in the turbo bearing, a narrowing of the oil supply line, or a bunch of molecules of RP lined up just the wrong way one day and got stuck.
Cars are wildy compex creatures, and I'm still amazed that they work at all, much less for tens of years and 100K's of miles,leftoutside in blizzards and summer heat, and bounced over what passes for roads. The only cars I've ever owned that have never needed repair came from the parts department, and were 1/43 scale.
Hang in - at least you know what has been worked on, and the quality of work that went into it.
Good luck!
