Unrelated topic: M73 V12 DIY tutorials?

It seems like there's a lack of DIY information on the internet regarding how to work on those E38 V12s, right? Are those motors so hard to work on that nobody even tries or what lol

It`s best to think of these motors as two six cylinder engines, arranged in a V-formation, sharing a common crankshaft. As a group, I don`t think they`re nearly as problematic as say, the 4.0 liter V8s from the older 740 series cars. The V-12s are wonderful engines....I once drove a 750i (maybe a 1989 ?) up and down some hilly, twisty roads. Drove it flat out, like I would drive a Corvette….the car was impressive as Hell. Impressed a group of bikers who were trying their best to overtake me, too....that never happened....

Yeah I heard about it basically being 2 L6s glued together. Though I'm wondering why there is barely any DIY tutorials out there like there is for the M54, perhaps it's too hard to work on?

Wake up and smell the coffee, Dude....

A: Only a small handful of people actually own these cars,

and

B: Out of that small number, I would guess that not more than 1% of them are DIYers

As they say, "You do the math"....

Those E38 750iLs aren't rare or expensive now though

I'm talking about the 90s 7-Series, not the new ones

I know EXACTLY what you`re talking about, which is the same thing that I`m talking about. Unless they are hard-core enthusiasts with a boner for a V-12, I would think that most folks would shy away from those cars, thinking about the mega-repair bills that might come along with them....

Planning on squeezing an M73 into an E46 (you won't be the first by the way)?
If you want DIY info you're looking in the wrong place, check for links in the E31 and E38 forums.

I know I'm in the E46 forum and no I'm not trying to put a V12 into an E46 because that would require an E31 manual transmission anyway

Ah I see what you mean, still surprising that a BMW that old doesn't have many dedicated DIYers like for the M54

Not really surprising, just simple math (like Bob said). For the lifetime of the M73 they probably made less than 200,000 but for the M54 they made more for every year, it went in Z's, X's, 3's, 5's & 7's.

Well what's surprising is the absence of knowledge on the internet in general really
