I have a 940 turbo, 1993. I have found what I believed to be a redish oil
in the expansion tank. So I removed the less than one year old raditor,
Hit a deer. Had a raditor shop test it and they told me the trany cooler is just fine.
So it must be engine oil. I have been checking the 700/900 archives. I did find
a post from a Chris H on Jan 14,99, Possible oil cooler leaking. Need to know
how to remove it and test it. If possible I would like to talk to this Chris H.
The information that I have gathered is if it is engine oil it could be head
gasket or the turbo or maybe this oil cooler. Note, I am not loosing or burning anti freeze. I am not loosing coolant but gaining a oil layer on top of the coolant in the expansion tank. Have never seen any foaming at the dip stick or the oil fill area in the engine oil or
the coolant tank. This is why I am thinking it is this cooler near the oil filter assembly. If it is trany oil it is the
raditor. Since I already have the car's raditors out and coolant drained it would not be hard to check this oil cooler if I had a few instuction. I guess that I should get the coolant tested for the type of oil. It looked red in the sun light so I thought it was trany oil. Raditor shop did not find anything. Could really use some help on this one. Is there any information in the 700\900 area?

Thanks
