Hello, my name is Dave
PCV stands for Positive Crankcase Ventilation and what it does is relieves the pressure in the bottom of the engine caused by the pistons and crankshaft moving which basically moves air like a fan would which causes pressure to build. If this pressure is not vented it can cause oil to get into the cylinders which in turn causes the engine to smoke. It is very easy to change the valve, it is in the valve cover on the top of the engine, I have attached the best diagram I could find that will hopefully help you locate and replace the valve. Please let us know how that goes and what the results are and as always thank you for using 2CarPros!
