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.

You guys are embarrassing these big retail repair shops who are trying to fix car problems by trial and error and parts slapping.. I'm proud of you Sirs!

[@TSTseminars]

That he is...Bernie has a great 4 and 8 channel labscope that has two time bases. Go checkout his stuff at his website automotivetestsolutions. Thanks for watching.

[@mike-yp1uk]

amother jam packed, watch more than once video. anyone can do it and i am certainly catching cars that kick butt some times. most instersting are the guest speakers you have. try paul danner sometime he has great techniques. thanks again.

[@TSTseminars]

Mike thanks for your kind comments

[@TSTseminars]

Rings and valves...thanks for watching

[@TSTseminars]

thanks for your comments and watching.

BERNIE IS ONE SMART GUY, I LOVE HIS VIDEO USING THE PICO SCOPE,,,,

[@TSTseminars]

Real easy just go to our tstseminars website and email us your information. Once we receive your info we can email you information on up coming live webcast. Remember that you can ask questions live and come back to KZbin to review over and over. Thanks for watching

[@daniel3190wells]

your videos are live. and I love that.

[@daniel3190wells]

Theirs no such thing as a stupid question just a stupid answer.

Daniel Wells Dan thanks for watching and making a comment

[@TheMechanic2]

a good demo to show a low cylinder on cranking is to remove a plug and put your compression tester in without the gauge. The smaller hole in the hose will provide a small amount of compression but not enough to show good.

[@TSTseminars]

yes it is and it's easy...thanks for watching

[@johnkimmel2612]

This is a very informative class here. I work in a fleet shop. The parent company uses the cheapest internet speed out there. As good and convenient as Pico Scope is, I can't see investing my own money in that regard. I do use my Vantage Pro along with my Solus Edge.

[@TSTseminars]

John sorry to hear about your slow internet....glad you enjoyed watching. Are videos are made to show different equipment or techniques to help techs.

[@MaicSalazarDiagnostics]

Very good information!! The only down is the quality of the video and sound!! Maybe time to do it again in a better format!!

My Hats off sir long live of for man kind.

[@SEXYTECH1000]

THANK YOU FOR THE INFO, I WILL CHECK IT OUT,

[@BillyGrism]

If a repair guy told me I had a bad cylinder based on a diagnostic, I would probe further. I would find it hard to believe that just looking at battery voltage fluctuations while cranking could identify a bad cylinder. Might work, but seems like there could be other factors at play, like the starter motor torque varying with angle, the alternator coming in and out, and other accessories varying. Next step would always have to be a cylinder compression check and/or leak-down test. I'm not sure why it would be hard to install a compression gage in any engine where you can replace the spark plug. Mine has a flexible hose.

[@johnfountain8143]

BillyGrism believe me its correct 99% of the time. crypton in the uk and sun (now snap on) in usa have been doing this since the mid 80s

[@Autofixpals]

+BillyGrism do a compression test on a 3.5 liter dohc Dodge. you have to remove the intake manifold, no way around it. most dohc ford v6 intake has to come out, toyota v6 intake has to come out. So should i charge you 3 hours to remove the intake and another hour for a compression test? 400 dollars to tell you something that i could have done in 20 minutes and 100 dollars. It's your money.

I live in French guiana. I would love to attend your class.great teaching.it is refreshing my skill.

thanks again

[@edwardboers2269]

If one was using the first look sensor in the exhaust pipe for relative pulse measurement, and the vehicle had dual exhaust....would the pipe that had no sensor it it need to be plugged with rags ect...? Great video and thanks for any help on this.

[@yourrealdaddy6332]

Edward Boers did they answer your question?

[@edwardboers2269]

Never heard any response

[@gpkook123456]

an hour of this guy repeating everything that is said to him I'm sure there's some good information here I just don't have a lifetime to wait for it

[@TSTseminars]

We are sorry that you could not find anything useful...maybe try to view the complete webcast. Also tell us what you would like to see please.

[@Amopower]

How does one become part of this live webex or whatever remote technology you are using?

[@Jpilgrim30]

One of the only times I’d disagree with you G is on the syncing of EVERY relative compression test. You can have a whole bank with no compression and without a sync it’ll look perfect and sometimes even sound ok as it’s every other cylinder. It’s few and far between but can really bite you in the ass.

[@TSTseminars]

John you are correct on that but usually repeating the test allows something to show up...once again thanks for your comment.

[@idada459]

Do u need attenuators to do compression test with the pico diagnostics sorfware

[@TSTseminars]

You need their or pressure traducers and it should work fine. Thanks for watching

[@ohyeagaming6090]

do u guys have a video up for the MODIS ultra

[@TSTseminars]

sorry no

[@saulrojas8659]

cant you hookeup to negative to

[@TSTseminars]

Saul and engine ground close to whatever your testing is best to use. Thanks for watching if you have not already subscribed to our tstseminars KZbin channel please do so.

Great vid but brandon sounds really really annoying

[@bobbrawley4466]

Typical webinar Takes forever to get to any point , five and a half minutes to nowhere

Bob maybe not everyone is at your level...we need to start form the bottom up.
