I picked up a neat little toy through the Amazon Prime Day specials, something that will get some immediate use and hopefully pay for itself down the line: a lighted borescope, for looking deep down into dark places like cylinders and inside frame rails and down into AC ducts. It’s pretty slick; the control pad has a nice wide screen a little smaller than that of my iPhone SE and a keypad with a set of sturdy buttons. The wire is permanently connected to the unit and is a good bendable but stiff material that makes things easy to direct the way you want it to. It’s got a video and camera feature with a 32GB card that allows for all the photos and videos to fit and be offloaded to a computer. Here are some pictures from the spare SV 345 in my garage:

Cylinder 3
(Cylinder 5 and 7 are missing because the engine is sitting next to a shelf, making access to those two plugs impossible right now).

There are clearly some carbon deposits directly on top of the pistons; I know the moisture is Marvel Mystery Oil so I’m not too worried about that. The carb on this engine wasn’t burning the fuel completely so it was probably knocking; hopefully it wasn’t run to the point where it overheated. If I get this thing on a proper stand I’ll maybe pull the heads off to see if I can clean the pistons and cylinder walls—but that’s in the future.
This weekend I’m going to use it to peek into the cylinders in Bob’s Chrysler and see what’s going on with the 440.
