In this video I show you how to use the Pico Scope to not only find out your vehicle has a blown head gasket but it will tell you the exact cylinder(s) that is having the problem. Why is this important? It is best practice to grab all the data you can before you tear the vehicle apart so you know what you’re looking for in the case where it is not obvious.
-Enjoy!

It seems I wasn't very clear on a few things in this video. I apologize for that. Hope this clears some things up and again sorry for not being very clear in my presentation 😊 https://youtu.be/hB1klKht-ck
Can you use a 1 to 3 psi dial air gauge instead of the transducer ?
Thanks. I have a head gasket leak and was told by a tech that did the diagnosis that my cylinders are wet from the coolant. I don't know engines much but Is there any way to remove the wetness on the cylinders?
If you have a blown head gasket who cares what cylinders it is on? I am not a mechanic but seems to me you have to replace the whole head gasket once you go into the motor. Waste of time.
My kid has a 1997 GMC Jimmy. It had a head gasket leaking into the exhaust. I thought the freeze plug had a hole in it. Finally seen the water was pouring out the exhaust manifold. Now it is ready for the crusher.
Even all this testing doesn't guarantee a bad headgasket on cylinder 3 and 4, what if you get it apart and find out the head was cracked? Either way a very cool test and makes me want to buy a pico and pressure transducer!
The clean cylinder will be the one with the leak.
Hello Sir. Great video for starters, do you think it would work the same for a diesel, I really like how you narrowed it down to which cylinder (or cylinders)
That's a good one
Ah I would of just re torque the head lol I had the guy in a machine shop tell me that after recutting the head on a Toyota
I'd like to know how much all you guys get paid for making these Auto videos I know you're not doing it just to help people out
Great test, had no clue this kit existed. Thanks
Blownhead gasket from #4
ðŸ‘
Thanks!
Hope the head is not too warped had 2 now had to replace engine ones I got in there
Great find love your videos I’m a Honda tech for 18 years now love scoping stuff have u scope wish I had pico have nice video same engine # 4 leaking with boroscope
Awesome pinpoint test here. 😃
Best explanation of pressure transducer mated to a pico scope I’ve seen, thanks from a 76 year old Vietnam vet!
I have GOT to get myself a Pico scope! Its definitely on my wish list.
I thought you were very clear, no need to apologise.
Thanks, clear to me. Good job.
I’m a tech myself Eric . So do you prefer using a pressure transducer instead of a good ol fashion leak down test ? I think the leak down test tells you exactly where your losing pressure because air doesn’t lie vs the pressure transducer doesn’t! Just sayin
Excellent! Ylojur use of diagnostic tools is the sign of a really great mechanic. No parts dump. No maybe. Just git ‘er done!
Mr O I'm looking for a scanner that will show cylinder graphs. When I ask dealers on ebay they all say there's don't.
hello Mr.O I'm an automotive tech in ohio and love watching your channel and learning new things from you I recently took a break from YouTube and I'm now catching up on some of the channels I missed I was wandering what exact Pico set up do you have. my shop happens to do a bunch of head gaskets and this would be an amazing way to show the customers who like to argue or want proof.
How much coolant loss would be a concern to check for a blown head gasket?
Great job thank you for sharing
Am I missing something, why would it matter where it blew out. You still have to make the repair the same way
Good and clear. I like ur videos.
That is an awesome test! I am going to try that with my scope. Did you by chance do the sizzle test, dropping any of the oil on something hot like the intake manifold to see if it bubbles? The reason I ask is, I wonder how accurate the sizzle test is. My son has a truck with the symptoms of a blown head gasket, but every time I try to boil some drops of oil, there's no boiling at all. It just smokes, so I assume that means there's no water in the oil.
You should change you motto to "If I can't fix it no one can".
