300 SEL Coolant Problem

[mriljim]

Has anyone had the problem with oil getting into the coolant? It doesn't seem to be getting in the oil however it may be I just have not seen it there yet. I replaced the head gasket pulled all the valves and did not see any crack is the head last week. Replaced the head gasket with the Engler and put in a set of valve stem seals and reassembled the car. Runs great but I fear I did not find the problem as there is still some oil visible sitting atop the antifreeze in the coolant tank.
Any help would be greatly appreciated in tracking this down. It is a very nice car with 187,00 miles on it.
