PCV: Postive Crankcase Ventilation...on our Volvo's it's a series of hoses connected from the accordion air intake hose all the way to the oil trap (also called the separator or breather box) under the intake manifold- when it get's clogged up, positive pressure builds up in the engine and can cause engine leaks.
Oil Trap: part of the Positive Crankcase Ventilation (PCV) system which does, literally, trap oil that circulates through the PCV. It requires periodic cleaning or replacement to keep the PCV working properly.
MAF: mass airflow sensor
