Rick and John,
I know this is about VW engines but...
Jabiru specifies a head torque CHECK (not re-torque) after first 5 hours, 10 hours
and 25 hours. Afterwards at 100 hour or annual. The purpose of the CHECK is
to determine if there has been any loosening. Jabiru says NOT to loosen the
head bolts and re-torque them, unless they are loose at proper torque setting.
If loose, no need to loosen them, just torque up to spec.

Glad we don't have to go through that drill with the 912 series engines.
However, I did have a cylinder head loosen and leak on my first 912UL, a
1993 model. My other two engines, 912ULS, have not had that problem. Don't
know of anyone else that experienced a loose head back then.

On the two Jabiru 2200 engines I have maintenance experience with, so far the head
bolt torque checks I have performed have not found any loosening.

My engine builder installed those teflon plugs instead of the wrist pin
keepers. I have heard good and bad about the plugs but at least I don't have
to work about my batch of keepers being too small.

John makes a real good point. Should we be backing off a bit and then
retorqe? My concern is that VW heads are assembled without any head gaskets.
The last thing I would want to do is allow the cylinders to move within the
head some and cause a leak that didn't before. Maybe only back off enough to
get the nut or bolt to move? Another concern is a nut under a valve cover
might become lubricated and be over torqued as a result (seems like torque
specks are normally defined as dry unless specified as lubricated). Any
thoughts out there????

I have been using an Ultrasonic cleaner for years, they are good for anything including
the fuel injectors on my Beech. It works good. Instead of water you can
fill it up with Kerosine or any potion that you want and they will do their
magic. Strongly recommended as something that works. Besides once you remove
your Kerosine you can put water and clean anything else that you want that fits
there. I did a quick search and found a unit on amazon for about 36 bucks. Well,
worth it.

I couldn't find the model I have but the above is pretty close in size to mine.
It does not take long for the gizmo to get the shmutz out, if you look carefully
you will see a little cloud come out when it first comes on vibrating. The
injectors on an IO-360 are a bit bigger than the carb ones so they have more
crap in them, I get a bigger visual effect than the Carb jets I would guess.

Sometimes the motorcycle jets I work on are too blame small for carb cleaner
to do much. Plus idle jets seem to be the ones that plug up first, being the
smallest.
I use a propane torch on them, holding them lightly but firmly with
needle-nose vide-grips. After getting them very hot I can usually blow out a
small amount of ash and have a clean idle jet.

I have been cleaning the injectors on my Beech for a few years using a sonic cleaner.
I did a quick G-search and here is a cheap one from Amazon ---
