Thanks Stuart. Hadn't thought of sealant as lube during torque sequence.
I really don't want to do this. It will be a "Hail Mary" if I do.
I'm 90% sure I'll leave that can o worms alone.

Tyler: AFAIK, there's no need to re-torque head nuts once head is properly
installed. Looking further in Bentley manual, interesting to see that
theres pages
on "Cylinder head resealing". I don't see any note there about
re-torque after X miles.

Why I'm considering head nut torque check, possible re-torque:

engine is likely leaking compression to coolant possibly due to
head(s) is "lifting off"
when under load at higher RPM. The leak may also be happening on
hotter days during
long periods in stop/go traffic. In that case it may be a "self
fulfilling prophecy" sequence of
events. Engine runs hotter, metal expands more, metal seal between
barrel and head
leaks, I hear bubbles coming up pipe to expansion bottle, coolant
level in fill bottle rises....

:(

Neil.
