Show Your Exhaust Valves

[jonhop]

Since my bird was down for annual inspection, I figured it was a good opportunity to snap a picture of my exhaust valves and post them for posterity... Cold compressions were in the upper 70's and the valve seats looked good. Here are the exhaust valves:

Nice circular patterns, no obvious signs of wacky valve behavior...

What camera and software are you using?

Clarence,

I'm using the native camera software in Windows 10. The camera is a Vividia Ablescope VA-400 USB Rigid Borescope Endoscope with 180 Degree Articulating 8.5mm Diameter Probe. $200.00 on Amazon.

And for grins, a little video of both valves in one cylinder attached below.  Pics and video taken with a $40 wireless endoscope, available at Amazon: https://www.amazon.com/gp/product/B01MYTHWK4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

That is great.  I had been looking for an IOS version.  I'm going to order this one.  Do you recommend any accessories, like the mirrors?

Mine came with a couple of mirror attachments included, but I found them to be low quality and not very helpful.  In the end, I got really good images by simply bending the head 180 degrees around and safety wiring it tight to the adjacent flex cable.  After doing so, the whole apparatus was still skinny enough to fit down the spark plug hole and look back at the valves.  Picture attached below, note the slight angle on the flex cable just past the camera head.  You need to bend a little angle there to look at the valves, as opposed to just looking back out the spark plug hole.

Fair warning: the "WiFi View" app you download to work with the camera is pretty klunky.  In particular, whoever wrote the app doesn't seem to understand the difference between resolution and digital zoom, and has unfortunately coupled them together.  That's why the highest resolution image I posted above only shows part of the valve.  You have to select a lower resolution to see the whole valve at once.  But hey, whaddya expect for $40?  I'm tremendously happy with the purchase.  It's perfectly adequate for borescoping, and at that price it's essentially disposable.

Thanks for the PIREP.  I agree, at that price it's worth playing with.

There is a USB only version also. I ordered that one.  That should allow use of other software for viewing it also a I would imagine it simply appears as a camera to the computer or handheld device.

Will know more in a week or so.

Vance,

Any chance you can post your video using YouTube?

This allows the IOS folks the ability to watch.

Apparently, the ghost of Steve Jobs still doesn't want us to see MP4 videos...

Best regards,

There's really not much to it, but ask and ye shall receive:

Wow and holy cow! That is really great visibility...

Thanks Vance,

I have the Vividia camera as well. The articulating head makes it easy to check out the entire cylinder.
