How do you replace the head gasket located on a 1989 Mercury Grand Marquis?

Answer 1

from my experience from other vehicles, depending on the side of the head gasket remove the valve cover, then it may be required to remove the intake manifold after that remove the head and scrape the old gasket off adding a new one in the process. the motor can still be in the car when doing this

the intake manifold must be removed, upper and lower, to get the heads off of any v-8 that is domestic
