Hi.
I miss the oil breather hose restrictor in my Porsche 911SC, 3.0, 1979.
Probably taken out, or forgotten by a previous car-owner . . . ? I don’t know
I observe the idle changes when i check the oil level.
Is this part important? Does it have an other function other than keeping the idle ok when I check the oil level with the dipstick ?
