Now for a liitle extra money, I can do colonoscopys on the side.
Yeah, at the my bro's shop, I've diagnosed two blown head gaskets with the snapon one.
Great tool for the price, compared to the $350 plus for the snapon tool.
How would you be able to diagnose a blown HG with a bore scope? Other than looking at stuff with the naked eye?
Alas that scope not that useful engine wise. You need one with a maximum 6mm head, so you can go through the precup, and into the piston chamber.
You won't see much though. I have the 45* mirror for mine and it is quite difficult to see the entire piston crown through a spark plug hole much less a pre cup opening. And that is with multiple entries with and w/o the 45* mirror. The angle of the angle of the visual field of any bore scope that I have ever seen is quite narrow. I was quite disappointed in what my Snap-Off unit would allow me to see. Now, if it were one of the medical devices that you can twist and turn remotely, it would be MUCH more useful.
