removing the PCV or slopping in RTV that clogged venting and the sound is
pressure blowing the seals.

I listened to it and it ain't any seals blowing. It's a rattle/knocking
sound, like a bolt, socket, nut, etc was left in there.

What platform are you on?

Some Macintosh users wrote to me in the web forum PM system saying they
couldn't change the name of the file.mp4.pdf back to the original file.mp4
name.

I don't know how to tell you how to do that on the Macintosh but I did just
now ask on the Macintosh groups.
https://groups.google.com/forum/#!forum/comp.sys.mac.apps

Are you on a Macintosh?

Hopefully the answer will be in this thread if someone knows the Macintosh.
Can a Macintosh person tell us how to change the name of a file?

It seems from my PMs on the web forum that the Macintosh users are having
trouble renaming the file to remove the ".pdf" extension so I asked on
comp.sys.mac.apps how Macintosh users can change the file name from
file.mp4.pdf to file.mp4 so they can watch the video.

Here are some of the responses if you're on a Macintosh and need to change
the file name from file.mp4.pdf to file.mp4 instead.

Perhaps you changed something that controls ignition action?
Like, something is changing the spark timing and it is now
far
too advanced? Spark knock? Maybe? hmmm....

I hadn't thought of that, where I did recently install the BMW dealer
software of the era when my car was new called INPA which allows me to read
all the electronic control units and reset the codes for all modules (not
just OBDII modules):
https://www.turboimagehost.com/p/36851946/inpa1.jpg.html

Some of this BMW dealer software can also program each module but I didn't
run any of that, and it can reset something called the "adaptations",
again, which I didn't touch to my knowledge.

I should be able to get the spark advance out of the dealer software though
https://www.turboimagehost.com/p/36851948/lean1.jpg.html

My OBDII reader shows spark at 6 degrees advanced at idle and then it jumps
to 20 and 30 degrees in the live data as I drove - where I don't actually
know what it's supposed to be. I don't even know where that data is.
https://www.turboimagehost.com/p/36851949/lean2.jpg.html

I have heard spark knock before where it sounds like marbles under load.
This doesn't sound like marbles. It sounds more like one marble.

This is getting confusing. Did you change anything with the BMW software? Did you even hook a PC up to the car while doing the vcg? If not, then this is a rat hole.

Are you saying you drove the car now with the noise?
