Deja vu? Weird. Even the comments are the exact same. (Not just specs)

Deja vu? Weird. Even the comments are the exact same. (Not just specs)

Yes I saw that... Asshole.

What I posted here came from someone I asked at BMW for a list of engine specs and that is what he e-mailed me... And I thought I'd share it.

So what the fuck is you point?

[rwh11385]

Come to think of it...

Accusing someone of plagiarism is a pretty serious thing.

I'll put up with all kinds of shit but you are very close to crossing that line into the catagory of "Shit I just don't have a sense of humor about".

You're a piece of shit. Or your trusted source is (unless it is Chapel), which I would be surprised at. What you posted is VERBATIM.

From BMW:

Hmmm...

I asked someone I know (a trusted source) if they could send me these specs and this is from the E-mail...

Would be interesting to me to know what came first.

Either way, if you CTRL+C and CRTL+V from Bimmerforums, or from your friend's email, you are adding no value of your own and just wanting attention from what other people have done.

You're probably great at AA meetings for taking attention off other people and focusing it on yourself, but your kind is not needed here.

You're wanting admiration for something someone else has done. Just like with Mason's bar. That makes you a piece of shit, which most of us already have known for a while now. You want attention so you leverage from other people interesting content, or make shit up to stir the pot.

Go back to your shitty wrench job you draw so much hubris from and stop trying to make R3V into your soap opera.

You're making it into a soap opera, not him.

I hope you're not too dense to acknowledge that.

See posts #8 and #13... lots of other examples out there as well... We work together.

There would be a better arena for us to slug it out than these threads though...

It's not admiration I'm after... Just making a living.

My guess is Mason thinks your a punk as well... Hell, John won't even post in here because of the idiots.

most definitely the way to sell products, call the forum you are trying to sell to a "bunch of idiots"
and I could care less what "Mason" thinks of me.

we would just like to see the proof of the crazy claims you put out-- all would be over with then.





BTW-- the difference between the M40--- M43 is the M40 has a timing belt to drive it-- the 43 was updated with a chain.--- The M43TU was the M43 with a plastic intake and a few small other changes.

the M40 (8V) was the replacement for the M10 (8V)and has nothing in common with the M42 (16V)--other than 4 cylinders--- probably numbered like that because of when they were designed "I guess"

I still love you .......
