Practical Pico: Non-invasive engine condition testing - Video presentation

In this presentation, we will show you how you can assess the mechanical condition of an engine without the stripping of any parts. We'll show you how you can set up, in a matter of seconds, for intake manifold, exhaust, and crankcase pressure testing. We'll describe how the results should look, to help you gain confidence in your measurements. And not only that, we'll introduce some typical faults, such as compression issues so that you can learn the basics of pressure waveform evaluation.

This has made me want a wps even more now! Great video lots of useful tips within the software you may not know!

[@SimplyDiagnostics]

Awesome video, shared it to our community. Thanks very much for uploading this gents ⭐⭐⭐⭐⭐

[@leesharp9646]

Great presentation guys, looking forward to getting my hands on the WPS :)

[@Mmmmgrolsch]

Thank you for taking the time to make this video and explaining everything in very fine detail. My next purchase is a WPS500 so this is very valuable to me to learn from.

[@DylanRabier]

Excellent video. Very informative. Thank you for sharing 👍

Super aula gostei muito obrigado. foi um show

Hi steve, just to clear something in this video. You state around the video time 1 hour that the disruption in the exhaust pressure after cyl.4 Exhaust closes is due to dramatic acceleration of the crankshaft. As a matter of fact it is induced by the double quantity of fuel cyl 2 gets to accelerate the crankshaft back to its target idle RPM. So the residual pressure after combustion of cylinder 2 is that high that we can see the result of this in de tailpipe pressure. Cheers Marc.

I am new to using pressure transducers. Can you tell me if disabling the PCV system will effect the crankcase waveform. Similar to blocking off the excessive loss in the exhaust by capping off one outlet. I would assume that the intake vacuum will have some influence on the waveform by way of the PCV system. Have you done any comparisons with and without the PCV involved? Obviously some systems don't lend to easily being accessed. I am very impressed with the time and effort you guys put into your videos. Keep up the good work. The level of detail that is now available to the technician is mind blowing. And it is so great to have people like you who are willing to share your knowledge.

[@stevesmith4724]

Hello and thank you for the feedback and additional question. I think this is best explained "in practice" as I believe PCV operation in conjunction with manifold pressure must influence the acquired crankcase waveform. I have started to answer a number of additional questions from the above Webinar here www.picoauto.com/support/topic21803.html and I will add this one ASAP (later this week) once I have the waveforms and conclusion. Thank you again, take care...Steve

[@stevesmith4724]

Hi Todd here is the reply to your question on our forum www.picoauto.com/support/topic21803.html#p98787. I hope this helps, take care....Steve

Great tutorial. Running and engine with a CR diesel injector disconnected is never recommended and there is a risk of damage to the ECU. Much safer to connect a spare injector .

[@alinduta5398]

which is the explanation?

[@Daniel-OConnell]

@@alinduta5398 I am not sure what your question is , but I assume you are wondering why disconnecting an injector may damage the ECU. The reason is that diesel injectors are fired at high voltage and currents. Solenoid types such as Bosch are fired at 80Volts and around 30Amps, piezo types use even higher voltages ranging from 180V-240V . These voltages are generated using specialised invertors within the ECU. These invertors use high speed switching circuits and storage capacitors, which are easily damaged without a load attached.

[@alinduta5398]

you mean the coil from injector is like a shock absorber for this high voltage?
