Oil looks nasty, loosing coolant
Oh no! in my 92 Se i just changed the oil like 500 miles ago. I checked it today becuase when its been cool out (~60 degrees fahrenheit) my oil pressure has been a few needle widths over 80. Once the car starts to warm up, the pressure goes back down to normal (assuming normal is 80 and the line after 40 is 80).
When i checked the oil today it looked kinda brown and nasty. Also i noticed my coolant was at less than half and i just filled it about a month ago.
Did i blow my head gasket? Crack in the block? The car seems to be running fine except sometimes it idles a little rough. My only 2 other cars (both chevy corsicas) had a blown head gasket that caused the coolant mix with the oil and basically kill my car slowly. is the bonne on its way out?
EDIT!!!: I forgot to mention that sometimes during driving my temperature will sometimes go over 200 for a short time then drop back down. It seems to happen at randomly regardless of the temperature outside or if im driving on the highway through the city.

Not a pretty picture. :( Two likely possibilities: plastic intake manifold failed or blown head gasket. Less likely: cracked block, cracked head.
Don't drive it with coolant in the oil or you will damage your bearings. A quick repair will prevent further damage.

This 92 may not have a plastic upper intake manifold, and if it is, they're not prone to the same failures as the series 2.
Can you tell us what your spark plugs look like? Any visible coolant leaks on the outside? Do you have a plastic or aluminum upper intake manifold? Pics?
I agree, to be on the safe side, drain the oil immediately.

Ok i can drain the oil but i have no idea how to drain the coolant. Also i changed the spark plugs maybe 2 months ago but i will check them. I dont know how to check my manifold gasket though. i will post more when i get home

To drain the coolant, there'* a petcock on the bottom of the radiator on the driver'* side. Open it up a little and let it drain into a pan. If you can't locate the petcock, disconnect the lower radiator hose and drain it into a pan. If you drain with the hose, it'll come out VERY fast and you'll most likely take a bath!!

For a full coolant drain, I understand that you have to drain the engine block also. I did my coolant change on the weekend, but could not figure out on how to get to the engine coolant drain plug. Any thoughts?

If you "backflush" the cooling system with water, you should be able to get all of the coolant solution out. Prestone has a backflushing kit that sells at Autozone and the like... I installed one in my old car, and it seemed to work well.
