Not quite the same, but when the turbo on the wife's Volvo blew a seal and sent oil everywhere, out independent who is a good personal friend told me that it was do-able, but a little finicky to get it just right. Suggested that he do the job rather than I, and I let him go at it. Not cheap.

But as the previous poster noted, I'd want a careful reasonable discussion that convinced ME that the blower was indeed, in fact, and really actually the problem.
