Loss of seal in the combustion chamber, especially if that loss is intermittent, can be time consuming to diagnose and confirm with traditional testing methods. In addition, volumetric efficiency losses caused by problems like valve timing shifts, improper variable valve timing operation, and restricted Exhausts can also be difficult to nail down. But by using the power of an automotive lab scope and a few accessories, technicians can reduce their troubleshooting time and confirm faults that would otherwise elude them. And that's the topic of this Motor Age/TST webcast featuring guest expert Bernie Thompson of Automotive Test Solutions. Click this link to subscribe to Motor Age! http://bit.ly/MA_YT_freesub
How to check for a jumped timing chain or belt
This video can be used to support Section 1 pages 17-23 in my ebook.
The method of timing verification shown in this video can be used on any
car. Even on old school, non-computer controlled systems. I am also showing
in this video how to properly align the timing chains on a 2003 Suzuki
Quick Tips for Evap Repairs
Global Leak Detection and TST present this seminar that is about how to
diagnose EVAP problems fast with a scan tool and a smoke machine. You can
use any scan tool and any OEM approved smoke machine such as a Smoke
Wizard, Bosch, OTC, MAC, and Snap On.
2010 Subaru 2.5 Variable Valve Lift Solenoid and Switch Testing
This video is a great review of Section 2 "Switch Inputs" and Section 3
"Transistor drivers and Output Solenoids" in my eBook.
On this system the intake valve lift is varied by two different cam lobes.
A low lift lobe and a high lift lobe. I misspoke in the video calling this
a variable valve timing or VTEC mechanism. This system does not vary cam
timing, but it does vary intake valve lift.
Testing Engines with a Labscope
This is not a class on old-school engine diagnosis. The compression gauge
takes too much time to use. Using a labscope, easily diagnose a bad
cylinder and timing issues using relative compression and pressure
transducers. Extensive use of the Picoscope is covered.
Pete Meier of Motor Age, G "Jerry" Truglia of TST, and Bernie Thompson of
ATS all contribute to this presentation.
2005 Trailblazer 4.2 #6 cylinder misfire
Case study on a 4.2l C.O.P engine with a misfire. For more info. on my
Ebook go to www.autocomputerstroubleshooting.com
How to perform an injector balance test with a scan tool.
Labscope Relative Compression Testing
Sometimes it's very hard to gain access to spark plugs in order to perform
a compression test. Here is how to do a relative compression test with a
uScope Getting Started and Secondary DIS Ignition testing
uScope Getting Started and Secondary DIS Ignition testing. This video will
walk you through the buttonology of the uScope quick scopes along with
insturctions on how to test DIS ignition.

Lab Scope Testing
A lab scope is a great tool that can tell you for sure if a part is good
or bad. But you have to know how to set it up and use it. This is one
in a series of new lab scope videos. How to use it to test a fuel pump
2002 Ford Escape 3.0 Misfire Case Study
Within this video I am covering parts of Section 1 and Section 22 in my
eBook available at www.scannerdanner.com. For more on the Picoscope and the
WPS500 pressure transducer I am using go to www.picoauto.com.
A look at the Verdict D7 Tablet with S3 Scanner and M2 Scope. So many have
said the scanner was slow and would freeze up, etc, This my first time
video, I wanted to let some know that mine seems to work quickly. This was
taken with a HTC Cell phone so the video isn't the best, as soon as I get
something better later I will remake this one for you. I just wanted to
share my experience for now.
Understanding running compression waveforms
Viewing the pressure waveforms from inside the cylinder of a running engine
can provide a great
deal of diagnostic information. Understanding these waveforms will help
you spot valve issues, blocked catalytic converters and restricted air
The equipment used is a PicoScope automotive oscilloscope and a WPS500
Relative compression testing using an automotive oscilloscope
For many years mechanics have been using labscopes and current clamps to
view relative compression during engine cranking. A PicoScope oscilloscope
when used with PicoDiagnostics software to improve on this test by
eliminating the need for a current clamp and displaying the resuts in an
easy to understand bar graph.
For more in depth diagnosis you can connect a pressure sensor to one
cylinder, the software then uses this as a cylinder ID and calculates the
actual pressure (BAR or PSI) for each cylinder.
