[grease]

I am new to this forum, as you probably can tell. I wonder what does nickelsil enchanced mean. I see people state it when describing there car.

It's a bit of humour used by some of us with original M60 V8 engines. The 1994 and 1995 V8's were cast with a Nikasil alloy...primarily aluminum but with a high nickel content in the metal. A problem was noted with gasoline that had high sulphur content...the combustion process created sulphuric acid that corroded the upper portion of the cylinder bore and caused lack of compression and poor running.

Most folks think of it as a North American M60 V8 problem but there were also problems in the UK and other European countries, as well as some Euro versions of the M52 engine.

BMW replaced faulty/affected engines..most with a new "Alusil" alloy engine block (although some early replacements were actually another Nikasil engine).

A "leakdown check" will help determine if the engine is affected with the internal corrosion problem. Several of us (Jeff (632 Regal) and I in particular) have original Nikasil motors in v.good shape and we're quite happy with them.

Being informed about the issue and having a potential purchase vehicle with an M60 V8 leakdown tested should determine whether a vehicle is worth purchasing or potentially a candidate for an expensive engine replacement.

Here's a good read on the issue: http://www.lestac.co.uk/bmw/nikasil.htm

Nikasil was an attempt at a nickle/alluminim/sillicone engine alloy. the high sulfer content U.S. gas used to have reacted with the nickle(?).. and made them fail. I can't find the link, but there was a good one with a good explination. if your car has a good deal of miles on it and it's still fine then its doubtful you'll need to worry.. lets see.. oh and it was only for the V-8 engines (m60) on the 540/40... i'm not entirely sure there's anything particulary enchancing about having a nikasil block.. heh... are they lighter?

correct me if i'm wrong (woohoo look i contributed somehting besides a newbie question!!!)

Duey and Jeff, as far as I know I too am Nickasil enhanced. I've tried finding the casting number on the block but can't seem to. Part of me really doesn't want to know so I haven't tried real hard. So is it on the passenger side or drivers side? Do you need to take his belly cover off or can you see up to the numbers with it on? Brett Anderson's web site says on the right side but that gets confusing for me when I'm upside down underneath the car.

they had a 6 cylinder that did it in europe also so it wasn't just yankee gas, they didn't find the fix till around 96-97 so at first they were replacing them with motors that could and would screw up just as bad. i don't think they ever figured out that went wrong with the coating, nic is not inherently bad as it's been used for dozens of years on a wide range of motors with great success even by bmw

displaces about 1.5 hp per cc more than an identical Alusil block. While the displacement is the same the pistons and rings are different resulting in almost "turbo" style of acceleration especially with a worthy engine management chip. You of course with a chip or without have the mandatory fixture of extra fuel prices because throughout the Nikasil future. Nikasil isnt acclimated to high sulpher fuels or low octane so you must use that rule or you can have a relapse and have to invest in the lower output and expensive Alusil V8 option. You cannot use the Nikasil pistons or rings in an alusil block as that would be an automatid referral to the copyright infringement act and your car will immediately be taken to the impound in the sky.

all that said, Deweys post was more relivent.

Was it also common to the late e32's and early e38's with the V-8 engines? I have been thinking of purchasing an e32.

slide under from the front and look directly above the starter just to the front of it, write the numbers down, count your blessings and be a proud owner.
