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?

Vacuum leak
Found this while changing my fuel lines. Hmm.
Smoke test for vacuum leak
Just thought I would make this video to show how the smoke test works for finding vacuum (or pressure) leaks. This is actually props to my very much loved fiancé Kayla Adkins because I was in denial that the problem was a vacuum leak on my own car and she convinced me to do one and what do ya know...PROBLEM SOLVED!!! What would I do without her! ;-)
How to check for intake manifold leaks
http://www.e30engineering.co.uk
A quick video "How To" guide on easily checking your inlet manifold and intake tracts for air leaks.
Code P0171
Code P0171 means the vehicle computer is showing the air fuel mixture is lean, either too much air, or not enough fuel. So, it is adding fuel to try and correct it. There are many things that can cause this code and some of them can be difficult to diagnose and expensive to repair. However, sometimes it can be a simply problem, with a simple repair. If your a do-it-yourselfer, try this first. It's a common problem and you might just be able to save yourself some money.
Intake Runner Vacuum leak (water test)
This is the second case study I uploaded to go with my "Vacuum leak testing without a smoke machine" video/lecture. Hope you like it.
1999 Ford Explorer, 4.0L OHV Engine - Vacuum Leak ??? - video 2
1999 Ford Explorer, 4.0L OHV Engine - Vacuum Leak search.
I think there is a vacuum leak in the upper intake plenum gasket. This leak is causing a Check Engine Light (CEL) code of P0171 (Bank 1 lean) and P0174 (Bank 2 lean). There are many reports of this type of Vacuum leak on the various Ford forums and some great how-to's on making this repair.
Where is my leak??? This is me spraying carburetor cleaner all over the area of the upper intake gasket area and plenum (plastic).
Vacuum Leak on Intake Manifold - Honda Prelude
Grabbed a can of Carb Cleaner and sprayed around til I found the leak. Appears to be right around Cylinder 1 Intake runner where it meets up with the head. Listen as the engine RPM drop when I spray the area.
Before this point, I have cleaned out the FITV, IACV, checked all vacuum lines, bled the coolant, and replaced the oring on IACV. I even plugged BOTH holes inside the Throttle body and the engine kept running! What does that tell you? VACUUM LEAK!
The intake manifold gasket was replaced with a Hondata Thermal Gasket, which then fixed the problem. What caused this leak? Poor workmanship and incorrect installation of the manifold.
****EDIT 10/20/11: I fixed the leak. It was the intake manifold gasket. I replaced it with a Hondata Thermal Gasket.
I was trying to figure out what that knocking sound is in this video...

****EDIT November 2012: I ended up replacing the whole motor because the piston rings failed. The loud tractor sound was valve related, but it was NOT valve lash or LMA's. It was a cam shaft holder that was loose as well as a combination of other things. Bent valves, loose/ worn out crank pulley.
Bad Spark Plug
Bosch Platin F5DP0R BUSTED (new)
I want to share in this video what a bad spark plug CAN look like. I have another video with the sound the engine was making when this plug (1 of 6) was installed. I brought the car (2000 Audi S4) to 2 different shops who both suggested replacing all of the lifters in the 30 valve engine (Audi 2.7T) as the sound was so similar to stuck lifters. Fortunately, I eventually diagnosed the problem myself and saved thousands. My main goal of this video has always been to help others avoid similar situations in the future by highlighting one way in which spark plugs (of any variety) can fail.
