I've got a question about the PCV system on a 1990 900S. Looking at the black plastic nipple that is installed in the valve cover, there are two barbed hose attachment points. One is large and has a hose that runs to the throttle body upstream of the throttle plate. The other is small and has...

Hey, So I've got the old "oil in the brake booster" problem - and all the built up oil is being sucked into the intake manifold when its at low pressure and burning off once the engines hot enough, dumping giant clouds of blue. I started by replacing the nipple for the connection to the intake...
