Oil Leak from Crankcase Breather Hose

[Rave Racer]

        Well, when I was driving my 16V Jetta to Florida, I noticed the same
thing.  On getting some advice from my VW specialist (NOT the dealer), he
said that it was the PVC valve and had no real importance other then to
evacuate fumes from the crank case back into the intake to be reburnt for
pollution control (no importance, unless you're a tree huggin hippie that
is).  Seeing as it had no real function, I pullled the hose off the airbox,
and bought a small paint can that I attached just behind the front grill,
and jammed the PVC hose into the hole in the top.
        I had a very noticable increase in low end power.  My guess is that
it was due to having less uncombustable gases in the intake.
        I did have to put a bottle of oil in after every 4 fillups though,
and had to empty out the paint can every 1500 KM or so.  I drove the car
like that for over a year.
