These are the casting numbers to look for :
Nikasil M60B30 1 725 970 or 1 741 212 old
Nikasil M60B40 1 725 963 or 1 742 998 old
Alusil M60B30 1 745 871
Alusil M60B40 1 745 872
Alusil M62B44 1 745 873 NOTE, all M62 engines are Alusil.
This is the only way to determine which M60 you have, short of removing a cylinder head.
You are looking at least $7k to replace the block maybe more. BMW never did release figures on the % of blocks that where replaced. See the link below and it will give you alot of info on the problem.
We have a 93 740il it has 141k miles and the original block. It runs great with no problems. That being said I would not buy a 540/740 unless the block has been changed. Its too much of a risk. We also have a 94 540ia I bought it last year in Oct. It had 99k miles on it. I checked the blcok #s and found that the block had been replaced. I don't think the used car dealer knew anything about the problem. I paid $13,500 for the car. It was very clean. I found out later that the new block was installed at 85k miles.
Take your time and you will find a nice car w/ the new block.
Hello, I am looking at a 95 540i for my wife. I have read however, about the engine blocks failing due to reaction with the sulphur in our gasoline. The BMWNA warranty runs out after 6 years...which is now. Has anyone had to replace their block? Is there a way to tell if the block needs replacing before I buy the car? If it does need replacing, what kind of costs would be involved?
I have been asking a lot of questions about the 540's over the last two days, I just want to thank all of you for your help!
