Well this is interesting...not good, but *interesting* nonetheless...
:-)
If my car is doing the same thing I'm afraid I'd not be aware of it.
With only the idiot light installed, mine could drop as low as 5psi
before the thing trips...I *think* that's the number.
Practically, it sounds like we need a lister who has fitted an oil
pressure gauge to his 1500 to report his experience. When you use
the phrase: "brake hard at an intersection or round a long turn at
high speed ", I'm guessing you mean *spirited driving* and several
notches down from real RACING...right? :-)
The symptoms sound very much like an engine that's low on oil. Have
you checked to see that the engine really does take most of the 5
quarts requires for an oil change? <U.S., with filter> Just wondering
if the dipstick might be wrong...no other brilliant ideas to offer
just now I'm afraid. :-)

Hmm..another toughie!
I would expect that a bad throw-out bearing, spigot bush or even
transmission bearings would manifest themselves with a sound that
changed in some way when you step on the clutch, rev engine, etc.
Since that's not happening my guess is the problem lies elsewhere.
Dumb question...does the "rattling" sound disappear when you lightly
grab the shifter? No chance you lost the little spring loaded
anti-rattle thingy in the base of the shift lever, right? Mine flew
out onto my gravel driveway during a rebuild the summer...fun time
finding it! :-)

The throw-out bearing is a very light press fit...no pin. Sounds like
some DPO got creative...OR:

You might be confusing the bearing itself with the throw-out bearing
*sleeve*. This part is indeed "pinned" to the fork. You don't need
to remove it tho', just use a small puller to grab only the outer part
of the TO bearing.
