380 sec questions

Gday, im new to the forum, and to mercedes cars. Today i got hold of a really crap 1984 380sec. Its got very hi km(411,000). It runs and drives reasonably well, but has been treated like garbage in every way for some time, and has the following list of problems...so far.

What seems to be a bad leak on the passenger side exhaust manifold or gasket..(rhd car)
...or it may b a lifter? Im unsure but its noisy... Noise noticably lessens briefly on decelleration.
Severe leak of self levelling fluid...appears to leak under car near the resivoir.
No aparent 4th gear engagement? (all other gears work..no slipping noticed).
Trans lever looks to be a bit out of place when in drive position.
Drivers window not secure in track
Runs a little hot..90-95 c
A/c inoperative
Oil press is at max when cold...and just under 2 at idle when fully warm, and at 3 (max) when driving. Is this ok?

Id appreciate any and all opinions on diagnosis/repair for the above issues.
Thanks in advance.

1)Oil pressure is fine readings
2)Self leveling leak could be from the ram connection via a hydraulic line going
to the accumulators
3)Car starts in second, not first, so you would only notice 3 shift points. 1st gear is gotten by moving the shifter into the lowest position, clicking to the left, and put back in drive, and than take off.
