See below. This picture is taken with the hood up, standing at the front of the car, engine cover removed.Yadkin, is there a hole already there to have accepted a dipstick should Porsche gone that way? Or another way of asking: how'd you do it?
Item 1 (hand-drawn circle drawn around it) is the dipstick tube. The factory puts a cap on it, and it can be replaced with an actual dipstick. You can't leave the dipstick in because it conflicts with the plastic engine cover. If you don't have a dipstick, use a stiff wire and measure 20" to minimum, 19-1/4" to maximum. This is from the top of the tube.
The dipstick tube is also used to vacuum out the oil, using a catheter tube to get down to the bottom of the oil pan. I have a MityVac 8 quart that I bought on Amazon for about $100; there are other systems available.
Item 2 is the oil fill.
Item 3 is the top of the oil filter canister.
So with the base engine, checking or changing the oil is a simple process.
