i worked for olds when that car was new. had alot of those motors go bad. you need to remove the p/s pump to do it by yourself-BUT you can remove the engine struts(mounts) and have a buddy(you trust) start the car and out it into reverse, now have him give it some gas so the engine rocks forward so you can remove/replace the motor/fan assy. - like that?

Get a can of Gunk and clean the engine according to the directions there (please do read them), with attention to the area around where the oil leak is. Once you get the motor squeaky clean, you will be able to trace back to where the oil is coming from. It may be running down the underside of a hose so you will need to look carefully. You can do all this in the driveway. You will probably have to let the engine get to operating temp before it will start leaking.

Head gasket. The reason for the cold then hot readings is the cooling system is getting gas bound by exhaust gases. A simple intake leak would just make you loose fluid, but wouldn't cause the other symptoms until the coolant was very low. Which leads me to, is the coolant full? The head gasket most of the time will not leak coolant into the oil, but instead coolant will go into the combustion chamber, and exhaust gasses will go into the coolant. You don't see any white smoke until the leak gets extreme. Then shortly after that the engine hydro locks from too much coolant in the combustion chamber. There is a tester that will test your coolant for CO gas. That is the proof of a head gasket leak.

probably your lower rad hose. shine a flashlight around underneath and see if you see it reflecting off of a liquid trail, that will tell you where the leak is coming from. you can also get leak tracer to add to your coolant that will leave a more visible sign.

Obvious is to tighten to valve cover.
The engine is actually designed to Not leak via the PVC Valve if working correctly there should in-fact be a negative pressure in the crank case.
Check and replace the PVC Valve.
Hope this tip helps
