Brian - whom were you running from when parked, her father? or Husband?

It appears I was way off thinking it was in the clutch system. I was thinking metal-on-metal sound. Sound has been clarified to be from air/wind.
My next guess was going to be alternator belt, but that has already been identified as not the problem. Also, I would think that Robbie would have indicated it was the fan, or in the fan housing, when others brought it up. So I think that's not it.
Perhaps a rubber cap came off of a manifold nipple or a tear in the manifold boot?

It is not a squirrel.
It is not a cat.
It is not the clutch.
It is not the cap.
It is not the belt.
Nor a SGKent nascar jack.


I'm currently stumped. I'll take my bus out this evening for a cruise to see if I can think of anything. But I would prefer to join Big Emma for a beer and scuba diving in Cozumel

Alright folks, thanks for being patient. Some of you are on the right track, and many good questions were asked this week.

The game was sort-of-solved on Thursday, but I wanted to take time and thank everyone for excellent suggestions and diagnostically relevant questions.

The most diagnostically efficient flow chart when dealing with noises on a Type 1 engine:

Step 0: Go back and check your work. What was the LAST thing you did to the car?*
Step 1: Hold clutch pedal down for a few seconds, engine in neutral.
Step 2: Rev engine and listen for change in noise relating to RPM. Do this clutch in and out.
Step 3: Cut engine in neutral and coast when it is safe to do so (power brake buses will need extra effort to stop after the first pedal press.) Noise gone?
Step 4: Remove belt and run engine briefly, revving it up and listening for noise.

Here we would stop, as the noise would be gone. If, in future VW exploits, the noise continues, reinstall belt and…

Step 5: Remove oil cap and use hose or stick your head in the engine bay and listen for noise in crank case. You'll hear a lot of clicking from solid lifters, and maybe some cam gear rattle if your assembly was lazy.
Step 6: Check engine end-play.

*Remember the oil change? The one on a windy day where this blew into the engine compartment and got sucked into the fan causing a whirring sound?

So far we've covered fuel system, electrical system, and engine, so next week will be another section of Bentley.

I want to reiterate that these threads are not intended to be answered by expert mechanics. I am happy to spend a few hours each week creating scenarios and responding to people who really want to learn and participate, but it's a tremendous waste of everyone's time when someone experienced chimes in with the answer halfway through a round of diagnostic questions.

Funny shit right there. A couple of years ago I had a whirring sound. Took a day or two to figure it out. Pulled the engine and a Post-it-note was stuck in the fan. Must have got sucked through one of the vents while on the highway. Don't know how else it could have got in there.

I never, ever would have thought of that.
I learned 2 things:
Oddities can be sucked into the fan housing and a six step diagnostic flow chart.
Looking forward to the next episode.

Having pulled the engine a dozen times on my '72 Superbeetle, and replacing the alternator 3 times, I had early thoughts about the fan shroud and fan though I wanted to see what everyone was going to pull out of their hats first. I wanted to hold off in case the differing systems in the type 1 bus case had a slightly different options for investigation than the standard dual port late beetle construction.
