1998 into 2000 5.0 Swap: Sandbox 2.000 Goes V8

Best part about the seat belt is it can stay with the engine.. no need to unbolt a chain and keep adding chain each time you need to lift.
Each engine gets a wheel to sit on and a strap for moving Blamo. Only special engines get a $99 harbor freight engine stand. My wife picked up a 1000’ roll of purple seat belt material at a yard sale,
So that helps

Nice work!
Ohv probably just needs heads haha

Heads likely, but the bottom end is tired too. I did a full leak down test before I gave up on this engine and there was a lot of hiss coming through the crank case, I think the rings are pretty well done. It's had oil dilution issues too.

Hopefully someone local takes it for all the good parts, I'd feel bad scrapping it all.

No takers on the 4.0 so far. If anyone need parts off it, PM me!

How about a Mounty front clip?

I'm slowly working my way down to this 5.0

Had a productive night last night! Got the evaporator box out and preemptively cut the passenger exhaust flange bolts because I figured they'd round off like they always do in the cast manifolds. But on the driver's side, where the frame blocks the bolts, I tried backing out the bolts and they turned just fine... that's a first! Maybe there's less galvanic corrosion between the welded-steel manifold and the steel bolt than there is between the cast iron manifold and steel bolt? Steel and iron are pretty close in galvanic potential, but that's my only guess as to why it was so much easier than every time I've done that in the past.

There's no market for these welded manifolds, right? This particular set is odd because they look like the early manifolds, but they fit P heads and have an EGR bung. They could probably be used in a Ranger V8 swap if someone wanted a fox 5.0 in a 4x4, but the cast manifolds would surely be better.

I also broke all the header flange-to-head bolts free and didn't snap any. Woohoo! Seems like this engine is excited to vacate the rusty Mountaineer and climb into the Sport and meet it's new manual partner.

Let me see your welded manifolds
They are probably junk but I want to see a picture anyways

Unfortunately there is not much market for used explorer stuff…except for a handful of complete psychopaths like us then that mounty front clip is like gold

Old Ranger engines always sell it’s just a matter of time

I started keeping all 4.0 and 5.0 builder engines a few years back. We are going to need “builders” in the future

Did you Sawsall off the front aprons to remove one big piece of the front inner structure?
I have 2 pair of 1995.5/1997 non "P" head factory headers.

Did you Sawsall off the front aprons to remove one big piece of the front inner structure?

No, it just unbolted. Two bolts each on right/left brackets, two on a bracket in the middle, and one anchor into the fiberglass on each end through the fender. I imagine the Explorer front end comes off the same way.

Exhaust is off, 4404 is out, trans cross member removed (trans is on the jack). Next to go, the 4R70...well, after I unbolt the torque converter. That was an oopsie when I pulled the trans out of my '99 Mounty, but now I know!

I looked at my two electrical diagram books and they are a 1999 book and a 2000 book. I very recently compared both wiring charts for the 104 pin pcm connector and they are identical. That gives you a head start on the wiring if that is your two years involved. I couldn't find where you had said.
However, there could still be minor differences in other places like the C-115 connector.

The donor is a '98 model, but it's built more like a '97.5 from everything I've seen. Since I deleted the auto trans wiring in the transmission sub harness and I need to make some repairs in the engine harness, I'm thinking I'll end up just building a custom engine bay harness combining the '00 4.0 OHV wiring and '98 5.0 wiring. The explorer has 3x as many turn signal bulbs, so I need to add that wiring into the Mounty harness anyway. My Sport was also built without fog lights and I spliced in a custom sub harness when I put on a '97 front bumper. I might as well combine everything I need into one clean harness now. It's going to be a good bit of work though!

I have a 96.5 5.0 book which had a 3 wire cam sensor and early transmission switch. I converted my early power train harness to the 1999 wiring diagrams. The 3 wire to two wire cam ps conversion was as simple as clipping, insulating and wrapping the unneeded 3rd wire into the main harness. I repurposed the rear o2 sensor wires to use on the DTRSwitch. But you can delete them and auto trans wires going manual. I understand about the hybrid harness that you need to make.
