3.0 Engine Stalls when Oil Cap Removed

Also, you drained quite a bit more than 8...

[DRACO A5OG]

10.5 Quarts. (3.2s)

But to be safe, add only 9.5 then fill as need after she is nice, hot and engine on.

If it dies when cap is open, indicates more than not that you have a vacuum leak.

Oh yeah, Welcome Aboard, she a Beaut :-)

Try the vacumm restrictor as mentioned in the pasted thread by gregwils.

If that's the issue, then start hunting vac leaks. But that can be a slippery slope and a PITA

or use the Cigar Method, just don't tel the wife

In the meantime, you can pinch the breather hose to stop the HUGE vacuum leak and check the oil. I would use a set of vice grips and a rag to pinch it off.

Just would like to confirm you're using the correct weight oil. I know a guy who ran 5W20 until I asked him He rebuilt his engine.
You should be running 20W50.

Update, Porsche recommends 10w-60 for SC onwards. 20w-50 for earlier cars.

10w-60w ? What? I love Alphas...had a GTV 2000.
