I am looking to buy an E34 '95 540i. It seems like it should be a reliable car (as long as it was taken care of), the only thing stopping me is the M60 problem with the Nikasil/sulfur. That one problem was the one thing stopping me from buying one right away. However, I have done a lot of research on the topic and I think that I have worked out all the loopholes. This is from memory, corrrect any mistakes; the mid-'90s M60 V8s had a problem with the Nikasil engine blocks. The sulfur in U.S. gasoline was eating away the Nikel in the walls of the block. Luckly for me, I live in California and the amount of sulfur here is the lowest in the U.S. However, it is still a problem. What I have done to "solve" the problem is to research, research, research. I have found that BMW (in order to fix the problem) replaced the short block with Alusil. So, when I go looking for 540i s, I intended to check the casting number on the short block, under the car to see if it was replaced. Also, having the records to see if it was replaced. Asking the seller if it was replaced. Checking the idle and ride quality while taking a test drive. That's all I can do, and then pray to the BMW gods that it has been replaced and that I haven't overlooked anything. Anyone have any other ideas? Is it safe to buy one after all that? How does everyone like their 540i's? Anyone have one that has had a previous owner. Any other common problems with them?
