Abstract
The present embodiments include assemblies and methods for releasably sealing a dipstick tube with a piston valve assembly in a sealable engine fluid measurement probe assembly. In an embodiment, the piston valve assembly is integrated in a handle portion of the sealable engine fluid measurement probe assembly. The seal may be established with an o-ring positioned on an outer diameter of a portion of the sealable engine fluid measurement probe assembly that is configured to be inserted into the dipstick tube. A port or opening on either side of the o-ring is coupled to the piston valve, or other equivalent valve assembly, for allowing air or other gases to bypass the o-ring, thereby releasing the seal between the sealable engine fluid measurement probe assembly and the dipstick tube.
