3rd gen sohc in a 2000?

[D17Fetish]

Hey all, not new to cars but inexperienced with fords... I work with VWs and hondas all day long and was a technician at a mopar dealership for a bit, but have done no more than replacing a t-case and tranny filter on a 95 explorer sport, and regular maintenance on ford products...

I have a 2000 Mercury Mountaineer 4.0 sohc 2wd with 240000 miles, it was making timing chain noises for a while and no compression on cyl 4 for over a year but it was a work truck and had basically no maintenance for atleast 130000 miles... i recommended fixing it over and over but got no results since the owners didnt care.

so the time came for the motor to die... blew a head gasket so the truck is down and that motor is definitely not worth fixing.

now its my truck and i have the motor out of a 03 explorer 4.0 sohc sitting in my garage. the block and heads look similar but valve covers, intake, ps pump, coil pack and so on looks different.

i was wondering if i transfer all these parts, including sensors and everything, would that motor work?

Long block only

The forum consensus seems to be as long as you use only the long block from the 2003 and everything else from the 2000 there should be no problems.
