- Savvy Aviation Founder and CEO Mike Busch, Savvy Borescope Guru Dave Pasquale, and Savvy Aviation Director of Analysis Joe Godfrey take you through the history and importance of borescoping aircraft engine cylinders, then how to shoot the 11 pictures in the Savvy protocol, then how to upload and store them using Savvy's new borescope image interface.

Well this has been fantastic. General aviation is such a rewarding interest. Great info, great products, great explanation.
That is a cool high-tech gadget I never had. I used a special flashlight with a light wand attached so to awkwardly peer down beside that and of course I always did the compression test when / as required. But if not retired now, I'd not give up the old compression tests for cylinders, I'd use both methods. And I'd put the flashlight and wand to their other small area uses where a simple visual look inwards and around is all that's needed, that was always handy when looking for dropped tools and hardware between engine parts. How technology can grow, it's amazing. 😊
Thank you so much for posting this video. Can't wait to inspect our cylinders in our upcoming annual.
Great video Mike, Dave, and Joe. Standardizing the picture series sequence is more thoughtful way to maintain an awareness of engine health. I always felt the same as you all about compression tests. Well done.
Another great presentation. Thank you
Sensational stuff Mike, love your work !
I just finished doing the borescope inspection on my Cessna 310R. While I understand the importance of checking all of these items to be thorough, I believe that if I had really good compressions, I would take a picture of the top of the valves in each cylinder, but would go no further. If I did find low compressions I would check more thoroughly, but I would not check every cylinder every time with all of these pictures. It takes me almost 2 hours to do the pictures on these two engines. It took longer until I got better at taking the pictures, but it still is not easy to look inside of each valve. Paying a mechanic for an extra 2 hours without bang for the buck does not make sense.
Respectfully, I'd reconsider your premise. A snapshot of a good compression reading doesn't tell you if you are on the verge of catastrophic failure.
Nice job! Thanks.
Thank you Mike, Dave, and Joe! Your borescope initiative is commendable. Quick question though. I first bought the Vividia VA-400 in 2019 on your recommendation. I've not been able to capture the complete crown of a piston on a Lyc IO-360 even when the camera is completely pulled back to the spark plug hole with the piston at BTC. Am I doing something wrong?
Thank you for this video and protocol. It will help me document our engines.
Now a question - are the red and green colors still valid for engines that mostly run unleaded auto gas?
Prepping for the inspection is also important. Disconnect the aircraft battery, removing the spark plugs, and having new washers and torque wrench available for spark plug reinstall.
Also if a secondary light source is introduced to cut reflection directly in to the camera would produce better image...
is there another B-scope video showing the examination of the CAM thru the case after a cylinder has been removed?
Mike is the guy. Subscribe to this.
The valve guide is displaced to one side by the camera. and that gap can be measured to further diagnose the guides condition.. but unfortunately there should be a way to insert a proper gap toll to full force the valve to one side to truly c what the guides are saying...
Wouldn't collecting material inside the cylinder be good for cylinder corrosion analysis?
Mike is there a way to create video high definition video where analyzing would allow for a more video more pictures more value....
I noticed that the image on Dave’s computer when he’s doing the bore scope inspection has a definite blue tinge to it, but the images shown afterwards as photos are a normal “real life” tinge. Why is this? All images I take with my Vividia borescope keep the blue tinge…
Do you have ever borescoped a Rotax 912 cylinder? There is not to much room to move the probe. Any suggestion?
What photo app is Dave Pasquale using. It is not the one from Vividia scope for Windows OS
I'm currently trying to find this out. I'm not pleased with the app from Vividia. Did you ever find a better solution?
WARNING! The valve stem part of this inspection is dangerous. I just followed this video and my borescope is now ruined. Sticking the camera into the valve guide is a good way to get the borescope stuck in the valve. When that happens and you've perfectly opened the valve to max open, it doesn't come back out. I had a tough time getting the camera piece out of the cylinder without removing the jug, but thankfully was able to. I wouldn't recommend anyone worry about trying to see the valve guide. Not worth the $700 I just wasted or the extra maintenance trying to remove the FOD.
He addressed this problem in this video a couple years ago. Sorry it happened to you, hope this video helps others prevent this problem. th-cam.com/video/2mJEoB8A8ZM/w-d-xo.html
Can bore scoop inspections be done instead of compression check on a Jabiru 6 cylinder engine? Does that meet FAA and Jabiru's annual inspection requirements?
Moving that prop around with that scope in the cylinder is not something I would do. Seems like unless your doing this on a regular basis with the experience doing it on a regular basis something bad could happen.
Remove all the plugs disables the engine. The worst thing that would happen is when the compression causes the prop to jump, but the engine will not start if you remove all the plugs and don't forget all the plugs in systems that have two or more plugs per cylinder. Also ground out the magneto.
Another meaningless video
