The reason the dip stick pops out is the tip of the dipstick comes in contact with bottom of the OEM oil pan preventing the dipstick from staying fully seated into the tube.
See Picture 1The fix for a vehicle with a stock pan is to either cut a small length off the end of the stick and then remark the level markings
or
Bend a lazy "Z" in the dipstick to make it shorter so it does not contact the oil pan.
See Picture 2or
Install a deep sump oil pan, problem is solved.
