Re: V-8 engine problems (archive)

: I would like to know the true extent of the engine problems on the early V-8's. I have a 95 740il and have been told everything from only a few are affected to "Its not a question of if but when." How many fellow owners have had problems and how has BMW handled the replacement? Also is BMW firm on the warranty cutoff of 6 years or 100k miles? Has anyone had BMW replace an engine under warranty after this period? I would think this is an actionable defect as I'm sure the pollution goes up as the cylinders wear. Any information would be appreciated.
: If you e-mail me with subject V-8, year, model, miles when engine replaced or current miles with no problem, I'll compile the statistics and publish them when I get enough responses.
: Thanks.

I have a 95 840 with 19k miles. The problem is with Nicasil vs Alusil blocks. Nickasil cylinders evidently erode due to high sulfur content in US fuels. It is my understand (as yours) that it is only a matter of time. My car is not currently exhibiting the symptoms but since I only have a year left on the extended warranty, I'm beating the bush with BMW and my local dealer - though not much response yet.
