There is a number of things but not knowing more you most likely got a vacuum leak
Possibly but not likely. If you suspect the PCV valve is bad, replace it. The two deal with different aspects of engine operations. While a PCV can affect the way an engine runs, and even allow for a buildup of crankcase pressure, it will not affect oil pressure. If you have low oil pressure it may be time to change to a heavier (thicker) grade of engine oil. For example, if you're currently using a 5W15 oil, change to 10W30. Higher numbers indicate that the viscosity of the oil is thicker and can revive the oil pressure of an older engine that is starting to experience some wear.
Disconnect the PCV valve tube from the PCV valve.Disconnect the PCV valve electrical connector if it has one.Turn the PCV valve counterclockwise to remove from the valve cover.To install, reverse the removal procedure.
Pull upward on the hose that the PCV valve is in. The PCV valve will pull out of the hose. The PCV valve is located in the valve cover.
Remove the PCV valve retaining screws. Remove the PCV valve hose. Reverse the process to install the new PCV valve.
The PCV valve has a check ball in it, That's what you are hearing. REPLACE PCV VALVE
pcv valves are always located on valve covers (but not all vehicles have pcv valves)
There is no PCV plumbing there is how ever PVC piping and fittings
PCV is positive crankcase ventilation
Diesels generally do not have pcv.

All engines have a PCV valve.
