I wanted to install an intercooler on mine but the crankcase breather / separator box was in the way I had to grind the plug flat I'm sure I can cut a slot in it to get it out...for the lower plenum of my install kitI have put 04+ SOHC engine into earlier trucks too, it gets a little tricky because the 04+ SOHC does not have the hole in the top of the block for the crankcase breather box that is under the intake of the 97-03 engines. However with some careful PCV plumbing a few tricks to work around the different intakes and thermostat housings it can be done and we have done it more then once here
The SOHC engine was built until what 2014?
The upgraded camshaft timing chain related components will fit in any Ford 4.0L SOHC V6 from 1997 to 2010. The installation and timing of the camshafts normally requires the OTC-6488 timing tool kit that can't be rented but may be purchased used for about $150. The installation and timing is not difficult but is labor intensive and requires attention to detail when following specific written instructions. Incorrect installation or timing can result in the destruction of the engine (pistons striking valves) on start up.
There are significant differences over the years in intake manifolds, valve covers, throttle bodies, EGR configuration and probably other things I don't know about or can think of at this time. The differences would have to be transferred from the original engine to the replacement engine. Its enough work to discourage many Explorer owners from purchasing a different year or make of engine. That makes less demand for SOHC V6 Mustang engines for Explorers which keeps the selling price lower.
