Oil spray all over engine bay (also white smoke from exhaust) '84 Euro 5sp

Even if the engine is overfilled with oil, there's no "path" (like a vent of some sort), in the area which is oily.
Therefore, something is leaking, somewhere.
Start with the cork gasket that seals the oil fill cap. The cork gets crushed, over time, and can leak oil.
Like Speedtoys says, check all the hose clamps and be alert for cracked hoses, right at the base of the clamps.
Nice looking engine compartment, BTW.

So, I've sucked a bit of oil out of the engine (via the dipstick, so it was a bit greasy and difficult to measure afterwards). Fingers crossed, I'll check again tomorrow.
Also, I think I may have found the source of my greasy engine bay. The oil filler cap did not have a gasket installed.
Nr. 26 in the drawing below.
I guess I only need the cork gasket, not the O-ring, or do I need both? (I have an M28.21 engine).
I'll source one right away, and hope it will arrive soon.

You need the gasket.

The new gasket arrived today, I'll install tomorrow, as it is pitch dark in my garage for the moment.
(I had to drain more than 1liter of oil to get the level to the maximum line.)
My other problem still remains, but should I start another thread? (Title not very specific...)
I had quite a scare today, as it gave me a really loud gunshot bang right under my *** while decelerating (put it in 4th to slow down after just cruising at 100kmh in 5th). It regularly gives some pops and bangs, but this one woke up the entire neighborhood. I had a loud one last week too, but this one was even louder.
It also consumed almost an entire tank of fuel in only 320km (200 miles). The low fuel light is about to come on in the next kilometers I think.
It did pass the CO test for the legal technical inspection 2 weeks ago.
Seems like there's something out of order. I'm afraid I'll have to get it to a specialist, as I don't own all the necessary tools you guys suggest.
I don't look forward to this, as I've owned it for only a few weeks and it has only been registered since last week. I don't want to part with it already.

Smell your dipstick. Does it smell like gas and is the oil super runny?
That bang sounds.like fule that wasnt burned in the cylinder and made it into the exhaust before it combusted.

Who overfill the engine? You should make an oiltest if you have 20 % gas in the oil.
Putting 7,5 l oil in the engine is easy. I would be sceptical if overfilling is the Answer to your problem.
Too much gas can wash the oilfilm from the walls of the cylinders = scored bores.
My 84 euro S can drive with one tank filling 500 - 550 km and I drive fast.
I f you loose the trottle Pedal my car pops too but not loud bangs.
Maybe you should test the injectors and the ignition. Are you sure she fires on all 8 cylinders?

look for vacuum leaks and consider replacing the MAF

Last workshop who filled the car was an independent Porsche mechanic in Roth, Germany. It does not make sense to overfill this much.
I'll get myself a vacuum tester.
I know the MAF and injectors are new. Can I easily find out if it runs on all 8 cylinders? It runs and idles smooth.

MAF may need to be readjusted after fitting
