Time to move on, Where to start??? Options

[catsltd]

Got the car running tip top.
Replaced coil,plugs.injectors,old rubber hoses,etc.

Now I am down to my biggest remaining problem:Oil Leaks.

When I had the car in to shop getting fucked up,they told me these were the areas that had leaks.

Rear Main seal.
Oil leaking from head(cylinder seal),I am assuming head gasket.
Differential side seals.(Probably NOT RELATED???).

The car is running great,but it is loosing a lot of oil through these leaks.
Questions:
1.Can I fix these thing without removing the engine???(This is the last thing I want to do).
2. Where do I start.
Thanks for any suggestions.
Grant.

Rear Main seal.

You 'can' remove the transmission without removing the engine and replace the engine rear main seal.
If you have FI, it is less work than removing the engine & trans as a whole.
If you have carbs, I believe it is about the same effort.

If you go that route, you would:
Disconnect all electrical to the trans/starter.
Remove the exhaust, shift linkage, and clutch cable
disconnect the axles at the trans end and tie them up out of the way.
(if you screw this up and the balls fall out of the cages, no need to panic)
loosen all the engine mount bolts (2X engine bar, 2X rear of trans)
support the engine in the rear of the case
crack the 4X bolts that hold the trans to the engine
remove the rear trans bolts & lower the engine while tipping the trans down
remove the 4X trans to case bolts
Slide the trans off ( almost need a transmission jack ~$50 at harbor fr.)
BLOCK up the engine - do not leave it on a hydraulic jack.
remove the clutch
measure endplay, if you dare (this gives a good indication of how "tired" the motor is)
remove the flywheel
pull the old Rear seal
install new seal and replace a few cheap FW parts
reverse above to put trans back on.

Oil leaking from head(cylinder seal),I am assuming head gasket.

Most likely the valve cover gaskets and/or the push rod tube gaskets.
Both of these can be replaced in a couple of hours and you would need to set the valves afterwards.

Differential side seals.(Probably NOT RELATED???).

These come out easily and can be replaced without pulling the "core" from the trans.
You can do it without removing the trans, but you still need to disconnect the axles & remove the output shafts
While the trans is off doing the rear main do the 2X output shaft seals and 1X input shaft seal
