I really don't have any idea what could cause your oil to be sucked into your fuel tank, especially at the rate of 5 quarts in 15 minutes. I'm kinda new to this stuff. Never touched a diesel until about a month ago.

The oil is going into the fuel. You need injector o-rings. They keep the oil and fuel separated at the injector but they are no longer providing a good seal. O-rings can be bought on ebay for a good price.

That clears it up very well thanx.
As Tim said Injector o-rings. I believe there are 3 per injector. They keep the oil and fuel separate.
What is happening is fuel is coming from the motor thru the heads and the injectors are using what they need and mixing with the oil and what is not used is returning to the tank.
You may want to look at your oil quality as well. Sometimes the oil pressure can get higher than the oil and then fuel will get in the oil. In your case your oil pressure is higher than your fuel pressure so it is going to the tank instead.
Get injector o-rings, Change your oil, Check your Fuel Pressure and shim if it is less than 55-60psi. I said that because it sounds like your FP may be a bit low because it is running better with the extra oil pressure and it is lower than the oil pressure.
Then run it a bit and you may want to invest in atleast one fuel filter.

Man, the more I learn about diesels, the more I wonder why gassers are even still in existence. Diesels: If ya wanna make more power, give more fuel and make sure they can breathe. Now you say that if you give them more than they can use they just send it back to the tank? Do I understand this correctly?

I'm a visual kind of guy. Pictures always seem to help out more when diagnosing problems. Here's a picture of an injector and the o-rings they are talking about.
For your idle problem I'd say the oil is a good canidate. You should not depress the the throttle pedal for starting. I'm sure if you did a filter change you wouldn't have this problem. I would imagine the oil is introducing impurities to the fuel system and filter.
