Abstract: A dipstick adapter assembly for use with an oil pan includes a front fixture having an inner face, and a backing plate coupled to the front fixture opposite the inner face. A first fastener is applied through the front fixture and fixed to the backing plate with a bond to prevent rotation of the backing plate with respect to the first fastener. A second fastener is applied to the front fixture for application to the backing plate so as to engage the backing plate and move the backing plate toward and away from the front fixture.

Abstract: A dipstick adapter assembly for use with an oil pan includes a front fixture, a clamping means coupled the front fixture, the clamping means being moveable through the hole to arrange the assembly between a free condition and an applied condition, in which the clamping means is inside the oil pan and the front fixture encircles a hole in the oil in direct contact against an outer surface of the oil pan and is sealed around the hole. The front fixture carries a gasket which is compressed against the outer surface, and first and second fasteners couple the clamping means to the front fixture and are adjusted through the hole from outside of the oil pan.
