Q: Intake Manifold on 1994 Ford Crown Victoria

What are the torque specifications for the intake manifold gaskets on a 4.0 1999 Land Rover Discovery

My wife's 2004 Ford Explorer is overheating. After her truck has been running for 10-15 minutes, You can see steam that smells like anti-freeze coming from the black plastic intake manifold area at the top of the engine. Does that entire black piece have to be replaced and how much đoes it cost? What seems to make the problem better or worse? Turn the truck off and allowing the engine to cool down...the problem gets better How long have you had this problem? Two days

i have had code 0420 come up for quite a while now and i suspect a leaking intake manifold gasket. lately the trans as been going into limp mode and i was wondering if the continued presence of coolant leak into yhe intake would cause trans to go in limp mode. another question is if i fix coolant leak do i need to replace catalyctic converter?
