I have a 94 Ford Ranger w/ the 4.0 V6. The heat shield came loose from the catalytic converter about a week ago. I have been meaning to go after it w/ some JB Weld, but never got around to it.
The girlfriend was driving the truck last night and when she came home she said "How important is that heat shield thing? I was driving and heard a noise that sounded like it fell off and skidded on the ground.
Me: Did you stop and pick it up?
Her: No, should I have?
So heres the question. If I don't have the heat shield on the cat. converter, am I going to ruin the cat. converter? If so, how quick will it go?
I checked w/ a auto parts store and you cant buy just the heat shield, you have to get a whole new converter which I don't want to do. If I was to jimmy-rig it and make my own heat shielf for it, what should I make it out of? Aluminum, tin....????
