300TE: symptoms indicate possible head gasket leak, opinions please?

[belagirl]

92 300TE- 154K miles. Just flushed the coolant, some white oily residue but basically coolant was clean. Now there appears to be a little white residue on the coolant cap.

No overheating, no milky oil, what do you think?

Is this something I can just not worry about until other symptoms appear?


Thanks for the help!
