my 88 m60b40 build

[Garageaholic]

Yeah, my 340i is nikasil and it has plenty of power and reliability. Has 120k miles..

Slammin is right. It is a moot point nowadays. If your M60 has over 100k and came from a working, driving car with no history of startup, power, or efficiency issues, then chances are your M60 is going to be just fine.

Don't get wrapped around the axle with Nikasil/alusil.

Don't lose hope, check it against the following block casting numbers, courtesy of Garey...

M60B40 Nikasil casting numbers are 1 725 963 or 1 742 998.
Alusil is 1 745 872. All American market M62's are Alusil...

If it's a Nikasil, it doesn't necessarily mean it has a problem or is compromised. Good luck.

ok so found out my block is within those years so it does have the nikosil. i guess ill just have to wait to do the compression test to decide if i want to keep it or just get a different block. But anyway i did some tear down today and cleaned up a few things and threw some paint on them also cleaned and painted the remote booster. im an idiot and forgot my camera where i took the pictures today so tomorrow ill post pictures of everything plus ill have more tear down news tomorrow anyway. for now lets just hope i dont need a new block because that may set me back a tad. Also today when i took off the intake runners i found a small pool of oil inside hmmmmm not to sure what that is, maybe pcv im not sure though i have to do more inspecting tomorrow. sorry about not having pictures again I dont know what i was thinking.

E38s all came with Alusil.

Not the case 1995 e38's didn't have them.

I bought a e38 740 from the bad block years and my buddy which runs a huge independent gave me some block numbers that he said if they are those, RUN cause even if it runs good then its highly likely it will not last long. I was lucky though even though the seller knew nothing about the first owner swapping the engine I was able to determine at 50k BMW authorized a replacement on the bad engine. So this is why I wouldn't bother if his is within the bad numbers. My friend says even if its ok now things could change as it gets ran on bad fuel or at least fuel its wasn't actually designed to run on. I looked for my papers on the block numbers but couldn't locate. I would assume you could locate through Google. You can obviously do what you want its just my opinion that was established by a well trusted technician.

Also you can tell your buddy that there are plenty of people w/ Nikasil blocks w/ over 200k on them that run great, and that nowhere in the US do they still sell high sulfur fuel which deteriorates Nikasil.

what? didn't we just establish that this explicitly is not the case? If Nikasil has good comp and leakdown numbers now, there is zero reason it will get worse later.

yeah if u have a bad block number I wouldn't even bother doing a compression test or using it for the swap as it will only be a matter of time before it lets go. IMO

[Vtec?lol]

since when do all '95s have Alusil engines??

Wiki has that answer

[iamsam]

well the benefit of an Alusil engine is that you know it has 50-100k less miles on it than the car does, which is always a plus.

[The Dark Side of Will]

US has low sulphur fuel now also... a Nikasil engine *should* be safe if it hasn't started haveing problems yet.

[slammin.e28]

Nikisil is pretty moot anyways.

http://www.meeknet.co.uk/e32/Nikasil.htm

In 2012 the Nikasil issue is over 20 years old. The Nikasil problem has really been and gone. The fuel available in the UK is low in Sulphur and any V8 that was affected (and there were very few genuine cases) are either sporting replacement engines or being recycled. Once the Nikasil-impregnated bores were compromised they very rapidly deteriorated to a point where they were un-driveable and un-saleable.

Wiki has the block numbers. I think even Jean posted them somewhere. Not hard to find.
