I am new to this and I am trying to find out some more information on my intake gasket problems. In a routine oil change, I was informed that I have oil leaking into my coolant due to a faulty intake gasket made by GM. And now I am faced with the expenses of having the gasket replaced and my radiator flushed. I was told that this seems to be a reoccuring problem with 3.1L engines, so anyone with any helpful websites or information please contact me.
