Howdy. Been a little while, but I'm back.
About a week ago the ohv in my '92 XL (the in/famous 4 door 4x2 sticker, aka the Explorer GT) is kinda dying. The middle spark plug of the driver's side bank (number 5?) goes bad every couple days (about 100 miles). It gets covered in oil/gas. I haven't run a compression check or anything, but I'm assuming it's from a broken piston ring or worse. Truck has 152k miles and I'm not sure of the previous owner's care. I don't think it was that great though. Fixing this is going to involve tearing the motor apart to get to whatever is actually wrong. When the plug goes bad the engine lacks a lot of power and you can hear a "putt" sound from the exhaust.
Then, of course as usual, when my mechanic will get down the problem, he'll point out that the rest of the motor is probably shot too.
So, why not F the old motor, and attempt to drop in a 4.0L SOHC? I'd get like 50 more horses out of the same block and they run smoother. I know of the chain tensioner problem but Ford got over that. I would probably get a used junkyard type one. Except for the engine harness, I don't see really any wiring to do. I can swap the engine computer and get one from an SOHC stick Explorer. I have manual windows, locks, transmission, etc so there's not much in electronics anyway.
WIll it bolt up fine to the M5OD? I know some Sports were equipped with the M5OD and the SOHC, but I'm just checking to make sure it'll bolt to MY tranny. And, will the engine bolt up? It would seem like it to me, but since I'm crossing a newer engine into a 1st gen truck I thought I should ask.
It makes sense to me. Not much effort to rig it up and a lot cheaper than a 5.0L. I'd like more power, but I'm not really doing the swap for the power or bragging rights. There's a decent 302 in the barn that I could have rebuilt, but I don't want to pay for the work, build up my own mounts, deal with the tranny bolting up, deal with carburation, etc.
Thanks guys. Has someone done this before?
