To check the PCV valve, temporarily remove it. If there is a lot of pressure and air flow coming through the hose it attaches to, compression that is suppose to remain above the piston is getting into the crank case. This may be due to a cracked or worn piston rings or rings, a cracked head or engine block, or a hole or crack at the top of a piston. If there isn't much pressure or flow at the hose attached to the PCV valve, the valve is likely stuck shut. If you hold it next to your ear and shake it longitudinally, you should hear the valve clicking back and fourth. This indicates it's likely fine. If you do a compression check of each cylinder and find 2 cylinders that are next to each other both low on compression, a blown head gasket is a likely cause. All engines will have some amount of air flow through the PCV valve.

Replace the PVC valve, it's probably clogged.

I dont think it is the PCV but its a good idea to replace the PCV at least once a year either way, and its very cheap, usually $2-$5 at autozone.
SOURCE: Had a rough idle and the engine dies while
does yurs have the idle air control motor if so look into that
SOURCE: STOP ENGINE-LOW OIL PRESSURE LIGHT COMES ON AFTER INSTALLING NEW
Before making any repairs I suggest you put an external mechanical oil pressure gauge in place of the sending unit and determine what your actual oil pressure is. That will tell you which way to go using real numbers. If this condition appeared suddenly it may not be a large problem, especially as you did not note any knocking etc that goes along with internal wear.
SOURCE: Rear engine oil leak....
Oil leak can be attributed to several factors.
1. Gasket failure.
2. Uncontrolled Crank case pressure Failure.
RECOMENDATION:
Tighten both the valve cover and oil pan bolts.
Replace the Positive Crankcase Ventilation Valve and vacuum line.,
INFO: PCV
This is a valve causes a negative vacuum on the engine while its running, As to say if it had a leak in a valve cover it should not be leaking while its running, only when the engine it turned off.
Hope this tip guides you in the correct direction to solve this problem.

Usually answered in minutes!
we went thru all of the proper checks, pcv was the culprit but it had been bad so long, caused other vacuum leaks at crank seal and rear main...evidently a common problem with vws
