I am looking at possibly picking up a bore scope to aid in tuning, and diagnosis. I am not looking to spend ton of money, but want a decent unit. Does anyone have any experience or recommendations with these?
how much are wanting to spend? snap on makes an ok computer screened model but the camera head and flexi line can be a pain to get in the proper position, my favorite borescope that i've used is the hawk eye works awesome and easy to see and view everything inside the cylinder. but your looking at a few grand for those. or for a couple hundred bucks you can buy a hand held visual inspection camera from Rigid which is just a smaller cheapo version of snap ons camera.
edit" did a check and hawkeye has setups for about 1g which is pretty good.
few hundred? then pretty much your only option is this http://www.ridgid.com/Tools/SeeSnake-micro I picked one up at napa a few years ago for 2-300bucks, i use it for finding dropped bolts and nuts in the engine bay. it might get ya by but, if your into real fine tuning and diagnosing i would say your better off pulling the head to get a real good look at whats going on imo
I recently bought this one, and have been pleased with it so far. The line isn't super flexible, but it has pretty good detail and is autofocus. http://www.voscope.com/page2.html They must have changed things a bit since I bought mine though because mine has a 4mm camera head and is the 24" long video scope. It's good enough to read wash and I can see the cylinder walls pretty good with it. I found it on sale somewhere online for just over $100. The articulating one would have been really cool but they are a lot more.
I use a stylus reach has a thin flexible neck and a LED bulb you can slip it into a cyl and light up the whole bore and still see around it under 50.00
