I'd actually take it to the dealer and have them have a look at it. I'd be curious to hear what they would recommend as the repair and how to prevent it in the future? I believe you've got the M62 engine and the SIB for this problem was issued back in March 2004 and to my knowledge never updated since. So the question is will the dealer do the same repair as the indy or will they implement the SIB fix as well? I wonder if they'll even pull the SIB!? Something to consider at least.
