That pipe is the crankcase vent tube and in your car, that would be hooked up to the PCV valve and would be run back through the cylinders.

The "stuff" coming out of there is what is called "blow by gas" and it's the gas that gets by the piston rings,and other stuff evaporating from the crankcase oil. If it's coming out in a large volume, it's usually indicative of the need for piston ring/sleeves. Diesels use oil spray under the piston crown to cool it so when the blow by is excessive, oil droplets from that spray and off the cylinder walls and splash from the crankshaft(The crankcase is a pretty dynamic place on the engine!) get expelled with the gasses.
There is no quick fix. It's usually rings and sleeves. You might try a heavier weight oil but if it works, it's only temporary.
