Oil change for 964.. drain plug?

This is my first on change on a 964. Where is the oil tank drain plug? I found the crank case plug but I can't find the oil tank drain plug.

Thanks.

it's in front of the rear wheel near the jack pick up, recessed in the frame.
Caution....when you fill it, you can't pour fast as its a long way from the filler neck down a narrow tube to the oil tank. You'll see. have fun.
oh, another tip. On mine, I have to release the airconditioner compressor and slide it over to the left to allow the oil filter to be removed. It was fun the first time to have the filter off and drooling as I tried to quickly move the compressor. What a mess!

Porsche must have made some major changes during the 964's lifespan. My 94 oil filter is nowhere near the AC compressor! The only hassle is getting the old filter off and the new one on while oil drains into the engine compartment. Lots of paper towels packed underneath the filter will help with the mess though. Also, don't forget the drain plug under the engine. Be sure to pick up two new drain plug washers as well.

Have fun. Get ready for the big whoooosh of oil when you remove the oil-tank drain plug.

Awesome. Thanks Guys.
