I think you have a gy engine
that is a vertical split you should get away with just replacing the old seal
remove the flywheel off the shaft
making sure not to lose the wood-ruff key
with a small drill
drill two small holes in the seal
with two thin screw drivers place them in the holes and draw out the old seal
with some sealant put the new seal in place
and with a flat bit of wood and a mallet or a small hammer
tap the seal into place
then put the wood-ruff key back in the groove
and replace the flywheel making sure to torque the flywheel down to the correct torque

Some times judders on take off

this is an indication of oil or grease on the clutch plate, or worn plate , over heated flywheel that has high spots and cracks and the same on the pressure plate. Basically the fix is the replace the clutch assembly, have the flywheel machined . While the gear box is out replace the rear main seal and the clutch shaft input seal ( the seal is behind the metal tube that the throw out bearing is on so it is a simple seal to replace.)

Why would I have oil in where my flywheel is and

Give more information. What car, what year model? If there is oil where the flywheel is, chances are you have a leaking rear main bearing oil seal or leaking gear box primary shaft oil seal. Coil packs? They should be there to make the car go.

I have a 1997 rav4, with an oil leak between engine and tranny. Is that an expensive fix?

Check that it is not the rear of the sump gasket that is leaking. If not then the fix will be to remove the gear box. If manual the leak may be at the clutch shaft input seal which is relative minor fix. If auto it will be torque converter seal and shaft seal . A bit more expensive. It it is the rear main seal then the clutch ( if applicable) and flywheel have to come off as well. All in all about $20.00 dollars for seal and about 6 hours labour.

Leak oil from underneith where the shaft comes out of the engine

If you look at the bottom of the engine, if you see oil on the large shaft coming out of the engine where the blade is attached, the PTO or crankshaft seal is leaking. It can be replace without taking the engine apart, but you'll need to remove the blade and adapter from the crankshaft, which can be difficult without the proper tools. You'll also have to remove the old seal, with a seal puller, or by using a couple self-tapping sheet metal screws into the outer metal part of the seal. You then would pry on the screw heads to remove the seal. Replace with a new one after cleaning out the bottom of the crankcase. Clean the PTO so that the new seal is not damaged as it is slid into place. You can use a length of plastic pipe to drive the new seal into place. Replace adapter and blade. Check oil level before use.
Oh, be sure it is not the drain plug, as it may have been left a bit loose if the oil was recently changed.

2002 Pontiac Sunfire GT. 2.2 Litre Ecotec Engine. Concern: Front Seal is leaking. Question: Does the engine need to be pulled to replace the seal?

No. The crankshaft pully can be removed through the right wheel well area. (This is the hard part) Once the pully is off, the seal is relatively easy to change.

Rear oil seal leaking. how to fix

If your sure the rear main seal is leaking then the engine and transmission have to be separated. It is easier to remove the transmission. If it's an automatic then after trans removal, you have to remove the flex plate to expose the seal. If it's a manual then the flywheel has to be removed after trans removal. It is a one piece seal that can be pryed out gently and a new one pressed in.

Master seal leak.

It's not usually called this, perhaps it was a "main seal leak"? Suffice it to say that it is not possible to replace this seal without removing the engine or the transmission as it resides behind the flywheel. Or perhaps they said "master cylinder leak", in which case it is a matter of replacing the brake master cylinder with a rebuilt unit or at the very least, the seals on top of the master cylinder that mate with the brake reservoir.
