Oil Dipstick

[FULLPWR]

Something I have been dealing with but just forget to ask.

when I chk the oil and install the dipstick all the way it engages fine at the handle and end of the tube like any other dipstick does.

but...... when i go to check the oil few days later its allways sticking out about a half inch or so, like I didnt engage it all the way.

so i've pushed it back in took for a granny few mile drive and ck it and its fine. but when i go terrorize the neigborhood and chk it it is out...

I dont know if I need another stick or tube or what.

any ideas what causes that?
and any ideas on the fix?
