I had one bosio nozzle in my 240D single tank WVO car. After about 5000 miles I took it out and it was shot - not chattering, bad spray pattern. The pintle was stuck in the bore (I hope those are the right terms). I had to boil it in purple power and pull the heck out of it to get it out.

I didn't know if it was the nozzle or the WVO setup I have (starts on cold oil, but with injector line heaters) . So the jury is out. The rest of my nozzles were shot, so I put in 4 new ones and I'm going to see how they go. So far so good - but only about 600 miles so no real test there.

They seem to carbon up quickly - less than 1000 miles, but I don't know if that's normal or not for any injector or WVO setup.

Cephallus - yes, I'd love to see the injectors as time marches on.

Alastair - any idea where to get those french Bosch nozzles in the USA? And, do you know anything about the Elsbett nozzles for WVO? Sounds like you know about these things - what do you suggest for a WVO setup? I set my nozzles at 117bar after you posted about 123 bar being too high.
