Just brainstorming here--
Instead of taking the head off, could you remove the valve spring keepers
and the valve springs, then rotate the valve in its seat, maybe "bang" it
up and down a couple of times, then reassemble the springs etc.? Seams like
that MIGHT loosen the chunk of crud.
Alternatively, (or additionally) you could pour pure Techron down that (#3)
intake runner a few times over the course of a day or two in the hopes of
dissolving/loosening the offending pard-crutticle (crud-particle). Change
the oil afterward to get rid of the Techron that flowed into the oil.

Subject: new diesel - - one cylinder, no compression
After just 10K miles on my new 1.6 litre TD engine,
I find that it began running very rough, like on three cylinders.
I loosened each injector in turn to ascertain that #3
cylinder was not firing.
I checked the compression on that cylinder and found it
to be zero! I poured a few tablespoons of oil down the hole to
seal the rings better if they were badly worn, and checked the
compression again. Read only 20 pounds. Must be problem valve(s).
I'm thinking that there must be a tiny piece of carbon
wedged between the seat and the valve, keeping it open just a
fraction of a millimeter, thus zero compression. Right? ? ?
Is there an optical snake one can introduce via the
injector or glow plug hole, which could snake around and have a
look at the valves, and while it's at it nudge the offending
particle out of the way?
Is the only alternative now to take off the head to
correct this minor but annoying difficulty?
The beast does not burn any Delvac 1 synthetic oil,
nor is the coolant circuit pressured up nor does the coolant
level drop over time.
Can a hydraulic lifter fail, and expand too much, thus
keeping the valve open a tad at all times? ?
Annoyed at having to take off the hydraulic head after
just 10,000 miles.......
