PA28 smoke source mystery
Hi All,
I have a perplexing question that I am hoping you can help me out with.
I completed an uneventful flight on a PA28 the other day and just as I was parking, noticed what looked like smoke/steam coming out of the ignition.
I immediately switched everything off and it didnt' return when I restarted it, did my run-up checks or flew home without issues.
Unfortunately (other than a suspected oil leak, as the a/c has been losing oil over time) there was no evidence that it ever occured and the the CFI called me into his office earier to ask if I was "sensitive" or "fearful of flying" as there is nothing wrong with the aircraft on inspection. (in short he thinks it may have been in my head, but I know what I saw).
My question is what caused the smoke/steam from the ignition? (which didin't leave a black soot in case you were going to ask/I cant' recall is here was a smell, it all happened very quickly).
I am worried about it re-occuring during flight and scaring another pilot.
Thank you for your help in advance,
