My engine is sucking il throuhgt the rings, thus letting out smoke in huge amount via exhaust with oil.

At 145,000 miles my car sudden started to blow smoke throught its exhaust in  
large quantity, which in turn means that the engine is sucking  oil throught the  
piston rings, could this be a problem develop from the air intake being less air
intake created the problem on the engine thus causing the engine to miss
sucking the piston through the block,
