white smoke from oil dipstick

Smoke coming out of the dipstick tube is most likely a plugged vent line, or you have excessive blowby, like compression rings are shot.

 

so an update. with a filler cap that didn't seal i lost average 11gal of oil per 30k miles of driving. After I put in a new oil filler cap that seals, I am losing only 4.5gal of oil per 30k miles.

maybe my dipstick is worn out too and a new dipstick would reduce the oil loss and the smoking (if the smoking is actually something like moisture).

 

i take it back. still high oil loss not sure if oil loss varies with outside temperature or amount of idling or what...

 

Have you by chance done any oil analysis?

 

yeah. done a few oil tests. Seems ok.

Same thing happened to my ISX.
I fixed the bad cooler and the white smoke magically went away.
