The oil quantity in my Jabiru 2200 is just a little over two quarts, so every ounce counts. Occasionally and over time, oil from the filter can leak back into the sump and indicate a higher level. To assure the proper amount, I always check the level before and after each flight. However, when hot, the knob on the dipstick expands and is difficult to remove. After checking with other Jabiru owners, I found that mine is not an isolated case.
To easily remove the dipstick, I fabricated a tool from a 1-1/2-inch-long piece of -inch square steel tubing with 1/16-inch walls. By grinding and cutting, I was able to remove the purple area shown in the drawing from the square tube. A hole was drilled in the center of the top, then filed square to accept a 1/4-inch socket extension.
The purple area is removed from a 1-1/2-inch-long piece of 3/4-inch square steel tubing. The hole on top is filed square to accept a 1/4-inch socket extension.
As you can see in the photo above, a short socket extension was bonded to the tool with epoxy. I then tightened two linked 1/4-inch hose clamps around the dipstick knob.
Placing the tool over the linked 1/4-inch hose clamps on the dipstick knob, I can easily remove the dipstick to check the oil level.
