Thanks for that, I'm keeping everything crossed!
One more factoid I forgot to mention, it's only ever had Mobil1 0w40 oil from new.
I know there are different opinions again on the best engine oil with some people going for higher viscosity. I know nothing about oil, but my hunch is that you'd be better off with lower viscosity in an IMS bearing with the grease washed out, assuming that the worst wear is happening on engine start up. Having said that, I don't think the longevity of the bearing is likely to be down to one thing. We'll probably never know.
