How To Find A Vacuum Leak - EricTheCarGuy
Vacuum leaks are one of the biggest causes of engine performance problems.
This video is pretty straight forward in it's approach to finding a vacuum
leak. On thing I might mention is that not all vacuum leaks are at the
engine. Some HVAC systems run on engine vacuum and can cause a leak under
the dash in some cases. I've even seen vacuum operated door locks. Just be
sure to be careful spraying flammable stuff on a hot engine, you don't want
to take one problem and make it a whole lot worse. You can also use a spray
bottle with water to do this same test. It may not be as effective, but you
don't have to worry about spraying a flammable substance on a hot engine.

Checking for vacuum leaks using home made smoke pump.
Inspired by Scotty Kilmer and refined by me. My 1993 Ford F-150 has some
issues like lack of power, poor gas mileage, slight rpm surge at high idle,
and 6 of the 8 plugs are showing really lean burn, also ocasional
overheating while driving. Any Ideas?
Paintless Dent Repair Using a Heat Gun and a Can of Compressed Gas Duster
Can you repair dents in an automobile with a hair dryer and a can of
compressed air? Yes and no. It depends upon the location and severity of
the damage. But as I have demonstrated, with a heat gun, $9 worth of Endust
Duster, and about 15 minutes, you can achieve some remarkable results.

Responses to the most common criticisms:
Q. Why didn't you just push the dent out from behind?
A. This is a hybrid vehicle and there is A/C equipment for battery cooling
that is located between the sheet metal and the interior finish. The dent
was simply not accessible from the inside.
Q. Why didn't you just use a toilet plunger and pull the dent out?
A. That may have worked on the larger of the two dents, but the surface
area of the smaller dent would have made that impossible.
Q. This video and photos of the dents have been Photoshopped and faked!
A. Absolutely not. I will gladly attest that this video and the images of
the dent, before and after, have not been retouched. I also have a witness
who observed the process and would attest the same.
Q. "Tapping" the panel like you did in the video would have popped the dent
out without the heating and cooling.
A. My attempts to pop the dent out with persuasive tapping by hand and a
rubber mallet prior to the heating / cooling did not have any impact.
Q. This process didn't help, you can still see the dents!
A. Yes. if you look closely you can still see the smaller of the two dents.
However, the larger of the two is not distinguishable to the casual
observer. This process made a significant improvement to the appearance of
both dents. It is not a factory perfect repair, but this is not a valuable
vehicle either. I could not justify the expense of a professional body shop
for a vehicle that is seven years old and +150,000 miles. This process
provided a good alternative.

Diagnosing a vacuum leak in intake manifold
Here I performed a 'propane test' but using Throttle Body cleaner instead
--Carb cleaner is supposed to be equivalent. Be careful, this is FLAMMABLE.
Have somebody look at the RPMs (revolutions per minute) in the tachometer
while you spray carb cleaner (pointedly) in suspected areas of the intake
manifold. In this case, I started with One, (uno -1) at the firewall,
driver's side of the air intake and proceeded clockwise in 10 total spots -
the last 6 correspond to 'the intake runners' where spark plug boots enter
the engine. The principle is that flammable carb cleaner is taken by a
suspeceted vacuum leak as you spray, and then it proceeds into the intake
plenum enriching the gas:air mixture and increasing the engine speed, thus
moving the needle in the tachometer. Once again be careful with flammable
mineral spirits. -.-. -
The problem turned out to be a broken vacuum chamber or vacuum reservoir
(typically found in Mazda Mx6 2nd generation) where vacuum is 'stored' to
be used by the EGR (Exhaust Gas
Recirculaton) Valve. Replacement of the vacuum chambers or reservoirs fixed
