The engine in my '95 540iA failed the leakdown test and has been replaced. Prior to that it never burned one drop of oil, even during driver's school weekends where I pushed it very hard. I think that the idle had gotten a little rough, but I only noticed in comparison to the idle with the new short block.
My car failed the test at about 60k miles. BTW, do you know for sure that your car still has the original block? Brett Anderson's web site has a list of block casting numbers that you can use to figure out what you have if you don't know for sure -->> http://frontpage.bestweb.net/~bretta/v8shortblock.htm
: Do the engines with sulfer damage burn/use oil? It seems that if the cylinder walls are harmed to the point that the engine doesn't have enough compression to start that it would burn oil. My 540i doesn't use any oil so I'm looking for a little peace of mind. I put Amsoil 20/50 in 7,000 miles ago and I've used only 1/4 quart. The car also has 114,000 miles so warranty repairs are out of the question.
