AFAIK, that's the only one available now.  they did this so you'll be more
inclined to take it in since it needs a special tool (at least that's what i
think, everything's a conspiracy...).  don't sweat it, though, the "special
tool" consists of two nails and a screwdriver.

not a wussy 90, not a superman 90, but an average joe (like you and me) 90.
but, on the 16V, it's 45, not 90.  i thought it was 90, also, but the
bentley does say 45 for 16V's.  the way i do it is i tighten it until i can
barely turn it 45, start it and see if it's too tight (it'll make noise,
like you said).  if it does, i loosen a tiny bit until the noise goes away.
i haven't had any problems in 7 years..
