Nah, didn't hurt it. I won't get into it because it will show how juvenile my friends and I can be, but my friend with the almost 400k 07 civic has done this many times on a hot and cold engine. On purpose. Yes I'm serious.
No biggie, didn't hurt it. Probably sucked some oil thru the pvc or something causing the blue smoke.
Don't lose sleep over it, monitor your oil consumption but this one time incident isn't going to hurt anything.
I had a 86 mustang 5.0, I had, in a fit of anger, hopped in it on a 30 degree day and ran it up to redline in the first three gears. I beat that poor horse every single day I owned it.
I got another story, but I don't want to incriminate myself...
