Boroscoping

[Robert986]

Since I´ve had some sooty exhaust pipes (only on passenger side, bank-1), I thought I´d check the cylinders out just to see if there might be any scoring.
I have no excessive ticking noice, or oil consumption so I´m not too worried, however, why not take a peek inside?

So, I have two basic questions:

1) What is the recommended routine? If I start by simply looking down the spark plug holes, some of the cylinders might be in bottom position and other in top position, should I manually crank the engine (via the front hatch) to get each cylinder in position for scoping? I´ve seen Jake scope via the sump to see the backside, I guess this is next level..

2) Anyone have a personal experience of what scope to buy? There are a lot out there... :-)
