[Vwdiesel] Any way to peek into the engine cylinders?

After the discussions of the use of veg oil mixed with
diesel fuel earlier this week, I started getting

A couple links were posted showing the possibility of
all sorts of damage happening when the veg oil is
simply mixed with diesel fuel.  

One of the sites discusses some symptoms, such as more
smoking, stinky exhaust (smelling like burnt oil
rather than the nice smell often associated with using
veg oil), the crankcase filling up with oil from
unburned veg oil making its way in, etc.

While I recognize valid points, I tend to be a little
skeptical of those sites because they are all trying
to sell me a kit of some sort.

My percieved evidence in my own use is that overall
smoke is very similar (though maybe a little more at
startup if the engine has cooled) could be a little
less once engine is warmed.  Exhaust smells, frankly,
very nice-makes me hungry sometimes and I've not seen
any signs of the crankcase filling with veg oil.

Long story short, I was wondering if there is any way
to peek inside the engine to see if there are all
kinds of deposits forming or if it is staying pretty
clean.  I thought of pulling an injector, but don't
think that would work because it is injected into the
prechamber, right?  What about a glow plug?

I'm not yet curious enough to waste a perfectly good
and not too old head gasket.

Is there something I haven't thought of?
