First of all, I would not run it that way. I have a 98 TC. Haven’t had the intake crack YET. Have priced them at NAPA & ORIELLY Auto parts. Intake alone is $220-230 where I’m at, MO. Quite abit of labor involved. About 5hrs for a good mehanic experienced with the 4.6 Ford eng. There was a class action law suit on this but, sorry, is long gone as far as you and I, is my belief. Personally if the rest of the car is in good shape with reasonably low miles (120-140k) I would fix. Mine has 71k. So mine would definetly be worth the fix. Hope this helps some. The guy with the $800 price is about right if he knows what he’s doing!
