Picoscope Compression Test - Livestream test

This is a test broadcast where we'll be demonstrating how to perform a cranking compression test using the Picoscope. We'll demonstrate how to directly measure one cylinder via 1 channel and then use a current probe to gather relative compression values. We'll also demonstrate how the save a reference waveform from each cylinder so that you'll end up with all 4 cylinders overlaid on one screen.
This broadcast is designed to allow us to test for an upcoming class we'll be doing in the near future.

Do not be discouraged by the low viewers focus on quality videos and the views will come automatically I really appreciated this video and thanks for making them.

Excellent quality tutorial. Fellow Seinfeld series viewer here! George and Kramer are my favourite characters there. 😆😆

What the value of a good mechanic? How much for Blown Shocks" "I don't have any faith in this gasket" 😂

[@abdul-kabiralegbe5660]

@@TechScottBrown Don't forget that mechanic who berated Jerry about Jerry's own car. 😆

[@TechScottBrown]

@@abdul-kabiralegbe5660 yes and that’s where my “no-faith” gasket comment came from. And what about the reasons for tire rotations? Brilliant script writing in that series!

This very cool thanks for great efforts.

[@Hscope-User]

Thanks for sharing great info, very helpfull💪🏽

[@saiautomotivemilton.7128]

I learned you can do the reference wave forms. Thank you.

[@TechScottBrown]

Glad I could help!

[@DTEAuto]

Good Presentation and great information on the valve issue 👍👍

[@TechScottBrown]

Thank you sir!

THANKYOU FOR UR TIME AND EFFORT AWESOME INFORMATION AND APPROACH CHEEEERS FROM ON, CANADA.

[@TechScottBrown]

My pleasure!

Nice video of the valve guide clearance check....rocking the valves side to side with comparison etc.

[@TechScottBrown]

Thanks, this vehicle was somewhat of a difficult diagnosis. This vehicle had been setting intermittent P0300 for the past couple of years according to our service records. Recently the client failed a smog check for a P0302. Compression was a little lower on #2 as you can see. A leak down test wasn’t conclusive as it was in the green but a little higher when compared to cylinder 4. The tailpipe pressure test revealed the leak.

Thanks! I missed the live stream.

[@TechScottBrown]

You’re welcome, I only “leaked” the livestream link to a few folks willing to help me test out my Vimeo account. I’ll likely have a couple more of these coming up and will make a wider announcement for those.

Sometimes ill just use battery voltage waveform and invert it to mimic current if i cant get my probe around the battery cables

[@shamsali1218]

Thanks for all information sir❤❤❤

[@TechScottBrown]

Always welcome

[@OneLegged-honda-mechanic]

Excellent! 👍
