Borrowing a borescope! What do I look for?

[Baz]

My mate has borrowed a Snap-On visual inspection device from his work and left it with me for the weekend! :rockon:

 

I am checking the internal condition of my TT engine before it goes into my car, it had an intermittant misfire before so wanted to make sure nothing major was wrong. The back two spark plugs weren't very tight at all, and I need to compare the plugs to charts I've seen before to identify any wear.

 

When using this borescope, what sort of things am I looking for?

 

I also have this spare engine sat in the garage that is apparently 'forged' - what markings/writing do the standard pistons have on the top and what sort of thing would an uprated one have (manufacturers name I guess?)

 

thanks for any help! :w00t:

Don't know mate, but can you video the insides?

Id be looking for any holes / cracks in the pistons, scrape marks on the cylinder walls. oil in the cylinders (as in a small pool)

 

check pictures of the wisco pistons mate vs stock, there should be some differences.

Some snap-on models do have video capture,would be interesting!

Yeah its got a video lead too so has a recording feature :thumbup1:

 

I had a quick look and nothing seems wrong, definately no cracks or oil, but the batteries went dead so will have another look tomorrow and try and get some videos done! :yes:
