Somewhere in my engine (that is, my car's engine), I have a vacuum leak,
probably, and I can't find it and it seems a smoke machine is the most
reliable way to find it.

Machines sell for $100 to $900, and I posted a video on how to make one
for about $30.

Another video suggested using a vape pen!

Looked at 5 vape webpages and only one item on one page didn't require
buying the pen and the liquid separately**, usually totally separately,
from different sources. Fortunately, the one exception was also the
cheapest.

Just $11 plus 1.30 excise tax plus $13 shipping, about $25.

**Not counting disposable fruit-flavored, which are illegal to sell in
Maryland. Not by mail or in person.



The email said it would be USPS Priority Mail and pointed out that
delivery would have to be IN PERSON signed for by someone over 21 years
of age.

My upstairs doorbell is broken and I can't hear the downstairs doorbell.

Do you think the mailman will leave the package without a signature, or
will I have to wait to the next day or pick it up at the post office?

Bum a cigarette off someone.
I actually have the tool you need, a stethoscope with a long probe
I have one of those -- it's very impressive -- and in all my reading and
video watching, you're the first person to suggest using it to find the
leak.


I also have what Bose calls Hearphones. They are an early version of
cheap hearing aids, only made for 3 or 4 years. I think they stopped
because the FDA is permitting better cheap hearing aids to be made now,
that iiuc won't require an audiologist to do the adjusting.

But they're almost amazing. I bought them to use at lectures but Corona
has cancelled most of the lectures. But I found other uses: Law & Order
reruns didnt' have the volume that all the other tv shows did so I would
wear them to hear what the characters were mumbling, and when doing so,
I could hear the rustling of cellophane. The creaking of the chair I was
sitting on, which I didn't even hear without the hearphones, sounded
like the chair was breaking. If I left the radio on upstairs, without
the Hearphones, I couldn't hear it at all, but with them, the upstairs
was so loud it interfered with the downstairs tv.

So I tried to use them to find the vacuum leak. I didn't hear any
hissing, but I could hear birds tweeting, birds that were not even on
nearby trees. They must have been 100 feet away. Did I read that
robins can hear the worms underground? Maybe it was two different
animals but some animal can do that. Now I appreciate what that must be
like.
that will find any kind of air leak like that but you are a little too
far away to borrow it.
That's true (email to follow).

Anyhow, I plan to find my stethoscope, try it, and get back to you with
results.

Try using it on the busted CD player too? Maybe you'll hear the music playing.
