...99 pontiac grand prix? ok here's the deal i have done alot of head gasket jobs in the past i know thats the key way for water to get into the oil. however i also know when the head gasket goes there is white smoke,loss of compression,and power.well this car for example has all power no smoke but a lil water in oil and exaust pipes. but i read up on the problem and unfortunatly pontiac made the gasket for these cars out of plastic.the car im doing has the busted gasket.cracked radiator,and exaust manifold.but like i said all power no check engine ligfht nothing can this be the problem
