Question
i have a 1991 dodge dynasty with the 3.3L V6 and over the past few months have noticed coolant loss only about a pint has to be added to the over flow tank i did find a small hole in the rad. so a i replaced it and all hoses
and now i am getting large amounts of coolant out the tail pipe but there is no oil in the rad. or water in the oil pan could this be the head gasket or intake the car still runs good but i stopped driving after the large amounts started to roll out so not to hurt the engine it does have 150,000 on it but has been well taken care of since new
would you have any idea of the problem thanks  

Answer
Even though you cant see oil in the coolant or vice versa,the head gasket or gaskets and intake will need replaced.The only way coolant can get out the tail pipe is through these gaskets so im afraid its a head job.I would recommend new valves because of the mileage also.Dont forget to replace your water pump as well.A good  machine shop will check the heads for cracks as i have seen this happen on this vehicle.Have them resurface and clean the heads when they are doing the valve replacement.
