Pressure Testing / Cover Gasket

I replaced the valve cover gasket on my car and the only tricky part I can
remember is the bolts suck!  Even using a torque wrench (ya, I do use one
once in a while, just not on spark plugs) so I didn't go he-man, I broke I
think between 2-4 bolts, including the bolts/nuts that the spark plug wire
cover secures to.

If that didn't frustrate, the fact that some of the bolts weren't at the
dealer didn't help.  Other, than that, a straightforward job, although I do
remember using gasket sealer on the half moons at the cam ends.

I replaced the leaking o-ring on my intercooler at the weekend. I don't know
how badly designed the brackets are on the 200, but on my S2 they are very
thin metal with 2 spot welds each. I cut the brackets off, and as I was
pressed for time welded them back on (I would have preferred to make some
new/stronger ones) in slightly different positions to get the I/C push-fit
connection as tight & straight as it can go.

This evening I pressurised the inlet up to 12 psi with a compressor. The 6
month old oil filler cap starts blowing by at 10psi and around this time the
#3 spark plug hole starts blowing. A couple of the F5DPORs were loose,
including #3, but the air leak is from the cylinder head cover gasket.

Is there anything to watch out for when changing this gasket? I don't have a
Bentley, as there isn't one available for the S2. I would appreciate any
