These two problems are related, your engine is overheating because there isn't enough coolant to dissipate the heat. There are three main causes for coolant in the engine oil:

1. Cracked head
2. Blown head or intake gasket
3. Cracked block.

The gaskets are an easy and relatively cheap fix, the head replacemnet isn't to difficult but will run you more than the gaskets. If the block is cracked (pretty rare) you'll need a new motor because it's going to comletelyu fail sooner or later.

1998 Oldsmobile Silhouette overheating

Is it leaking antifreeze underneath the engine at all when it sits overnight? If so I would say the water pump is shot. If it isn't leaking, it could still be the water pump but it might(hopefully) just need a new thermostat. And driving it when it's hot like that to the point where it starts to run rough means you run it too much like that and your engine will blow up and there is probably already damage. So check it out before driving it to much more.

2001 olds silhouette engine overheats

Time for Intake Gaskets and possibly head gaskets, very common problem with these, the intake gaskets go bad and the coolant actually burns in the cylinder and of course the cylinder pumps air into the coolant system because of intake gaskets being bad. :-(

2001 Oldsmobile Silhouette...Overheating, changed the thermostat, no signs of leaking, and the oil looks fine. At idle it takes 20 minutes to max the temperature gauge (red) and while driving it take

Usually the problem with no heat and overheating is low coolant, thermostat, or a faulty water pump impeller.
The radiator may not be full of liquid coolant, or the pump may not be moving the coolant thru the block.

Why is there oil in the radiator??

If you are certain it is engine oil then you have a blown head gasket. Transmission fluid also runs in separate passages in the radiator because the radiator contains the transmission cooler as well. Sometimes the transmission cooler inside the radiator can bust and cause transmission fluid to mix with the coolant. You need to be certain if it is oil or trans fluid you are seeing.

Anti freze leaking from back of motor?

The 3.1 and 3.4 engines are bad about blowing intake manifold gaskets. I have changed a bunch of them. Check you oil and make sure it's not getting coolant mixed in it. if it is don't start or drive it. this will destroy your engine.
