sailor Excerpt from the book has been posted, which thread is the question (here or in MkIII).

Pattern is the normal rotation starting from the center and working outwards, final snug down to "tight" is adequate.

As I type that I realize that many may have not seen a typical torque rotation pattern, starting from the center and working outwards in a criss cross or spiral pattern. Tighten to touching, then to snug, then to tight.

Few have the inch/lb beam type torque wrench that's easiest to use on those tiny fasteners, pull out a click type ft/lb one at minimum setting and it's out of it's accuracy range. Way too easy to twist them off before knowing it. Once you start putting pressure on that long lever it's already too late

Very true, who even has these, need to be rented. I did a search for this TSB and didn't find it, I was sure ford had told me there was a TSB when they repaired mine. Anyway I would follow ford service manual to do this correct.

Tighten too much & break fasteners.
Pretty sure there is a gasket adhesive needed as well. You may be right on no torque is required, but torque ratings can be required to prevent exactly what you are describing. Its to not over tighten just as much as not to have it too loose.

Make sure you torque cover down to revised specs as this was a tsb I believe.
