Coolant

My friend you need a head gadket

or two.

Time for a junk yard engine

Coolant coming out of the exhaust is never a good thing.

How is the vehicle otherwise? How's the mileage? My 99 looks like it came off the showroom floor, but needed a new engine. New reman from Ford with 100K warranty. Comes with oil and plugs. You'll have to re-use injectors or purchase new ones. $2600 bucks if you can install it yourself. Compare to what the repair will cost if you cannot do the work yourself.
