I've seen the turbos grind themselves to death, but I mean, yeah I probably was being a bit general about that. Of course there are other things that can go wrong with them.
As for how we get payed for the warranty work, Let say your turbo job is 10 hours work. LR pay us, as an example 80 dollars an hour for 10 hours only, whether it takes 3 hours or 20 hours, to work on that car. If the same job had to be undertaken but the customer was paying, we would basically get double that.
I got more information on that oil feeder pipe, I know the man who engineered it, it is a case by case part, there are only a few around and they may have needed to split the body to insert the new pipe. They basically took the old pipe and put a one way valve in it.
So yeah, don't know what more to add, plus I need to get to work /sigh.
Hope this eases your mind a little, I'd be glad to answer any further questions you may have.
