[V8] questions

Faxed the pages over.
Oil leaks - major players:
1 - distributer seals (most likely) - large o-ring seals on the body of 
the distributor. After removing the cap, there are 2 hold down bolts. 
The body is pinned to maintain alighment, there is no gear for the rotor 
drive (slotted), just note the direction the rotor is pointing. The leak 
goes directly onto the header as it angles down. Feel the bottom of the 
distrib body - if wet, that's a source...
2 - Rack  (second most likely) - with the upper engine cover off and the 
intake box removed (4 bolts for the engine cover, phillip screws at the 
back that are hidden, remove brace bar to get the screwdriver down there 
to back them out (I usually leave these backed out for easier removal). 
2 nuts hold the intake box on.
Reach down and feel the bottom of the rack boot - if wet and really 
sticky, and the boot is torn, your rack is leaking onto the h pipe. This 
is a real pain in the ass job - I've done it 3 times. 6-8 hours of work. 
The rack comes out the passenger side wheel well. Around $250.00 rebuilt 
from Jorgen.
3. Rack hoses - the short return hose can loose its crimp and leak on 
the driver's side - look behind the master cylinder.
4. Rear main seal - the most evil - trans job is 10 hours of labor. You 
need a lift. To verify, remove the engine sensors on the driver's side 
of the engine toward the back - if they're wet, its probable. This is 
relatively rare. I had one that was actually an upper pan gasket leaking 
(there's a cast upper oil pan, and a stamped steel lower pan).

Typical water temp is pretty tough, really - it should be 87-100C. If 
you're moving down the highway - 87. In town, slow traffic - 100-102. 
Cold weather can drag it down. If in the summer it tends to be low and 
running rough, your O2 sensor can be toast. Your mileage will be too 
(10-12).
If temp exceeds 105-110 in traffic and stays cool on the highway - time 
to replace the radiator.
