If that line from the OAS is actually plugged you must have one gummed up engine and an oil pan gasket that gushes from the pressure buildup.

Hey Levi,

I think it's

944 107 187 01 (PET Illustration 104-00 Pg001 #20), and
999 181 152 50 (PET Illustration 201-05 Pg001 #30)

Cheers

it goes to something on the right side of the master cylinder.
sorry couldn't be more help. maybe someone could chime in.

yea...i think over there was the carbon canister and emissions stuff....that's prob why it was just chopped and capped.

It goes to a vacuum solenoid that vents the fuel vapor from the charcoal canister in the fender area. You can plug it, but this defeats part of the evaporative emissions control and is not a good idea.

The larger hose comes from the AOS, commonly cracks / hardens with age and leaks vacuum badly. It is stupidly expensive from a porsche dealer (~$60) but is difficult to replace with standard hose because of the bend at the end. I don't recall if it changes size either.

any harm on a stripped track car w/o a cat?

[Zero10]

Well it allows the charcoal canister to vent to the atmosphere if that line is left open. If you are on a stripped track car you've probably removed that thing anyways, adds weight
