loosing oil

I have a oil leak its only leak when driving when im in park position you dont see no oil spots but if you look under the car the bottom oil pan is soaked with oil .

There is a plug on the back side on top, where the distributor was until they went to DIS ignition. The o-ring tends to disintegrate, leeting lots of oil leak down from above. Use a mirror to look behind the motor. That might be what you see. Did you fix the overheat? Running hot will make 'em leak oil outta everywhere.

I found the screw unscrewed it and turnded the car on and start filling the radiator with fluid until it floowed out.Then i put the screw in real fast and tightend it and put the cap back on the radiator and let it ran for about 20 minutes. It seem fine but when i drove it it was getting back closer to the hot warning indicator it didnt bubble back in the resevoir.I not sure if i did it proparly i didnt get to flush it like you said as far as the hoses, by me working two jobs it would have to be a weekend thing let me know if i did this right.

to relace the o-ring Jeffco describes, take the air intake tube off the throttle body and you should see it. The fel-pro part # for the o-ring is 70800, and I also use a 70194 flat paper gasket between the top of the block and the oil pump drive for extra insurance. They are available at any auto parts store for less than $2 each, and pick up a throttle body mount gasket too, as you need to remove the throttle body to get clearance to remove the oil pump drive. You didn't specify the year of your car, so I can't give you the T/b mount gasket number, as they vary slightly from year to year.

I have a 1995 i dont really think that my o ring is on the driver side because thats where my air intake unit is at and my oil pan botom is the passenger side that is what is soaked in oil

If the leak is on the passenger side, it's either a timing cover seal or possibly a power steering leak. My 91 was covered with oil on the front of the motor, ended up being power steering fluid from a leaking return line.

Let it cool off, and fill it again with the screw loose, keep doing that over and over until no more air comes from the bleeder each time you top it off.

It is possible for an air lock to keep the heater core from seeing much flow. Focus on the overheat and getting the air purged first, the rest might fall into place.
