So I've got the crack and the subsequent leak. I've been looking around the web for a replacement manifold. I've found some but they don't mention the Explorer as one of the models it will fit. Is there any difference between any of the 4.6 motors that would prevent a mustang intake manifold from fitting up on an Explorer motor or any other one for that matter. I know there are like 3 or 4 different blocks as far as place of manufacture but I thought "modular" would lend itself to interchangeability of parts among the various makes. Its an '02 model with an W in the 8th digit of the VIN.
