Crank Case vent pipe

I rebuilt my brakes and replaced all of the hydraulics in my car. Sadly I am not so great with the tube bending so some of the paths aren't currently the best. However I think they are pretty much out of the way of being crushed. Sunday Afternoon/evening I took the car out for a spin around San Francisco, just to see how everything works. I still need to adjust the brakes some as it does not apply perfectly evenly (mostly the wheels aren't engaging at all the same time, once they are down they are all stopping about the same.). There is plenty of documentation on that one.

When I got home after driving for an hour or so, I found myself a little woosy with a nasty headache. I was told that the missing crankcase vent pipe would cause problems of gassing out the cockpit, so I need to take care of that right away.

I assume I can go to just about any crappy autoparts store and buy a hose of the right diameter/length to the crankcase vent pipe. Does anyone have the basic specs of this hose for a BN1 off hand?

Hi Josh,
Not sure which "vent" pipe you are talking about.

There is a pipe "road draft tube" on the side of the tappet cover. It extends down quite far to a location where it is exposed to forward motion air flow. There is a vent on the side of the valve cover. The draft tube is intended to create a suction on the crankcase when the car is in forward motion. Air enters the top at the valve cover & exits via the draft tube. The top vent is originally connected to the back of the air filter with a piece of 5/8" ID hose. Almost any hose will work. When the car is not in motion & the draft tube not working, fumes exit the top tube & are hopefully sucked into the air intake.

All questions answered.

I was talking about the breather vent in the valve cover that hooks into the airfilter, I suppose "crankcase" is not the right terminology.
