There are different lengths of dipsticks for Porsche oil tanks. You need to know if that oil tank is from the same car as the engine. Then, you or we can look it up right here on Pelican.

There is also a thread on dip sticks in the archives somewhere. When you get this info, you can probably make a correct DS with a file mark for the levels. It can't interfere with the oil level sending arm in the tank, the one Grady referred to.
