ok got the money up for a full tune up so i bought all the parts. i havnt got them installed yet but i can see my intake gasket leaking. would an intake gasket leaking antifreeze into the motor cause it to pop and sputter? i figured it would because it would be just like having water in the gas. so i had to cough up some more money to get an intake gasket, even if thats not the problem it still needs replaced.
