Dipstick wont stay in the tube... 91 2.6 Trooper
 

I have a 1991 Trooper 2.6l/5spd

130k on the odo, supposedly a rebuild <1k mi ago.


When I go to check the oil, the dipstick is always out a little. About an inch or so below the handle.

What is going on here?

Oil level is correct, oil pressure is around 55psi. Just did a tune up and old plugs all looked normal, just passed emission test too. new PCV valve too.

Guesses welcome.

Thanks
