Episode 11: Finding Vacuum Leaks
Finding Vacuum Leaks with Home-Made Smoke Machine





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. Read more at... http://blog.yagelski.com/2011/10/paintless-dent-repair-using-heat-gun.html 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 the problem.

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.
