Another old thread coming back to life.
The factory moved the oil tank back to the forward position with the introduction of the 964 and used their leftover oil doors on the C4 lightweight and the not too shabby 959. Just one more endorsement for the ‘72 leading the way!

I know this thread started with a focus on the oil door, but it’s wandered to the broader question of the appeal of the 72 model year in general. I’m a fan of the E model in particular, which three magazine road tests in the day showed was slightly quicker to 100 mph than the S model. The means that the 72E was the quickest regular production car Porsche had ever built. Maybe this is why my wife once said, “Don’t ever sell this one.”
I am refurbishing the oil system in one of these '72 gems right now. It is an old friend's car.
I'm all for getting the weight of the oil and tank forward.
I'm NOT for the massive corrosion of the rear quarter panel and oil tank that results from road dirt settling between the tank and fender!
If you own one of these 'special' cars or are contemplating buying one I would recommend removing the tank to see what is going on up there.
When I didn't have my own 911, this friend used to LEND me his...
One day (in 1977) as I dutifully checked the oil level I missed the dipstick storage tube and dropped the dipstick into the tank-
It was a dicy 45 minutes with magnets, coat hangers and lots of colorful language before I retrieved the dipstick. We sure laugh about it now...
I still like the idea of this design, after all, the driver determines what flap is accessed for fill-ups-
But the corrosion is insidious.
Look now or have it pop out in this convoluted and very difficult to repair correctly area!
The compression ratio on these '72 cars resembles a Briggs and Stratton- 7.3 to one?
It is expensive to upgrade new Pistons and Cylinders but without C/R the engine will never perform like it was intended.
Luckily the car I'm working one has been upgraded. It runs really well with the 9.? to 1 setup.
You can help the situation immensely by assembling an inner fender shield positioned forward of the tire. I made mine by fashioning a custom frame from light aluminum bar stock, made a pattern from cardboard, transferred it to a thin rubber fabric and riveted the matrix together. It attaches nicely to the oil lines. I'll get a couple of photos when I get back in the garage.
I see that the Singer has the External Oil Door. Wonder if the Oil Tank is forward of the rear wheel.
It is, as this starts as a 964 and that is the stock location.
