I have been getting a very slight amount of oil (half teaspoon or so every 200 miles) in the reservoir tank that collects on top of the anti-freeze. No coolant in the oil, no smoking or overheating and no idiot lights come on and engine runs smooth. I have no oil leaks to the outside of the engine i can find anywhere
Possible from transmission oil ? if oil cooler on same radiator
Oil in a radiator indicates that the transmission oil cooler in the radiator tank has failed and leaking transmission oil into the radiator
there are 2 possible fixes
fix one is a new radiator
fix 2 is to give the radiator oil cooler a miss altogether and opt foe an air cooler mounted in front of the radiator
the advantages here are that the radiator then has a bigger capacity to handle the engine heat as there is no hot transmission oil adding to the engine heat
the second advantage is that the transmission oil is being cooled to ambient temp and not engine temp which makes for longer transmission oil life
the disadvantage is that it cost a bit more than a radiator initially but the long term savings are real
oil to air oil coolers are available from auto transmission shops and quality auto spares shops
SOURCE: Oil in coolant
oil in the coolant generally indicates a blown head gasket. If the head gasket is blown, oil and coolant could be getting into the cylinders. You should have a mechanic check it out. I don't know a whole lot about dianosinng diesels. If you can get the glow plugs out, turn it over and see it any water or oil blows out of the holes.

you need to remove door trim panel there are (2) 7mm screws that hold panel on .. 1 is behind the lower red light lens and the other is behind switch panel for the power window switch . remove both screws and remove small black panel above door trim by pulling strait off .(now there are (4) 11mm nuts the hold mirror on 2 are behind the small rubber plugs in front of door that you can see with panel on and the other 2 are under panel that you can see after panel is removed . the wiring need to be disconneced you may have to remove speaker for acess to feed new wiring down into the door good luck

Light should have stored code. Go to local autoparts chain & get free scan for codes and go from there. Saves all that guess work & money a lot of times. Write down code(s) and let us know.
SOURCE: have oil in my radiator fluid reservoir tank (1996 v6 3.8)
Twice in two years now my Saab 9-5 has had a pin-hole in the oil cooler, which has caused oil to flow into the reservoir. A way to tell is if coolant/oil is coming out of the reservoir cap. The reservoir cap is rated for the pressure of the coolant system, which is significantly lower than the oil pressure. When there is a hole in the oil cooler, oil will be forced out at relatively high pressures, causing the reservoir to fill and then over pressurize and spill out of the cap.

make sure thermostant is good. most important is to make sure you didnt blow a gasket when it overheated, if you have a 3.8 engine those are famous for blowing headgasket. anyway have a block test done first, its a liquid they use to see if exhaust gases are entering the cooling system, good luck ,hope this helps.
