1995 530i Nikasil Problem

[632 Regal]

not like I care but just wondering. Nothing left to replace but that damn PCV plate I have put off for a couple years now.

Well guys, it seems christmas arrived a bit early this year! Just got an email from BMW USA and here is an excerpt:

"Our records
indicate that your vehicle does not fall into the range of vehicle's
where potentially the sulfur content in some grades of fuel reacted to
the Nikasil engine. Please note, for those vehicles in this range, BMW
had extended their original factory warranty by 2 years or 50,000 miles,
whichever occurred first.

The vehicle you purchased is not one of these vehicles. I hope this
information is helpful."

Well, mine has some points to it where it seems the harmonic balancer (Jeff, do these 8's have them) is off...around 900-1100 is one, and out-of-gear high idle around 1900-ish has a harmonic rumble/oscillation that is not the in-gear.

I don't really know how to characterize "smooth"...it is smoother than the other 'beast' in the garage?

could you describe "smooth"?

smooth like the beginning of 'welcome to the machine'?

It seems to be out of balance at certain RPMs, where normal folks would call it a miss...but it goes away. Mine is the same as in the rpm range to the off balance situation as is yours...probably balanced off to the same rpms so it runs silky at autobahn RPMs. I dont burn oil or smoke or any crap but it does idle a bit tough at 550-600 like a miss. Probably that bastard PCP plate I dont look forward to.

The little motor in the racecar idled at 18-1900 and seemed smooth all the ways to 8500 but it was so loud and violent who cared about an extra vibe here or there.

drove myself nuts looking for the cause. several people said it is due to the cams being tuned for the higher rpm power band. i wish i knew this last year.
oh well, it will most likly need those new gaskets & parts any way.
