Greetings all,
Owner of 98 Explorer V6 OHV, recently did upper intake gaskets and all vacuum hoses to fix lean codes. When I was reassembling the plenum, I fear I may have stripped one of the throttle body bolts. These are a set of four bolts, identical to the ones that hold down the coil pack. They are self-threading with a course (deep vee) thread.
They screw into plastic holes on the plenum. I'm not sure why Ford didn't put thread inserts into these holes; I failed to observer proper torque for these bolts as I discovered in my Chilton manual.
Anyone repair these? There are three different repair approaches:
1.) Heli coil, They sell sets. Anyone do this? How hard is it? Do the
springs hold well in plastic? What size bolt, and what kit do I need?
2.) Fill holes with epoxy compound, re-drill and use same screws.
3.) retap to next size bolt.
...you could also drill these out to next larger size and put in screw inserts...
Anyone have a suggestion?
