    The info in your link is correct -- bad rings or a defective Positive Crankcase Ventilation (PCV) system can cause pressure to build up inside the engine block.

    How about ripping out the AIR system?

    Has absolutely no affect on crankcase pressure. The system simply pumps air into the exhaust manifolds on cold startup for about a minute or so. This helps the catalytic converters come up to operating temp quicker and cuts down on cold start emissions.
