This "can" be an indication of badly worn rings. The compression is lost through the rings into the crankcase and the pressure escapes the engine through the PCV system. Also be sure to check all of the PCV related parts. Make sure the hoses are connected and that there is vacuum present to the PCV valve. A clogged PCV system will make a mess in your air cleaner to.
