4.0

Howdy rangers. I'm doing the dreaded overdrive sprag replacement on my 2002 automagic 4.0 4x4. (It broke a week after purchase, no warranty. Fork me.) I've removed the exhaust (including the stupid y pipe and O2 sensors), drive shafts (front and back), transfer case, and I'm a few steps away...

Howdy there, I am trying to figure out the bolt sizes for my Ranger. It's a 1997 4.0 Manual transmission. The M50D-R1. I'd like to replace the bolts while I got the trans out.

Currently trying to engine swap a 2000 4.0 ohv from a 5 speed into a 1996 with the 5r44e, the flexplate, trans bolts, and threads in the engine don’t match up. Has anyone encountered this before and is there a way around it like some sort of adapter, probably should have researched a little more...

I’m looking to tcase swap my 1991 manual 4.0, with the electric shift 4x4 (manual hubs thank god). My electric shift really hated the cold snaps this winter, and as a result of using it my 4hi no longer works, and my 4lo has become 4hi. Honestly, I don’t really want to diag as I still can use my...

I have a 2006 Ford Ranger XLT 4.0 manual Just driving down the road I lost power to any gear i tried and the truck wouldnt go over 20, also in a sort of limp mode chugging back and forth. I limped it to a part store and towed it home. I have 0 check engine lights, replaced the fuel pump...

Sorry guys I'm not too sure where to post this. I woke up yesterday morning and someone had drilled a hole in my gas tank. It's a 2003 Ranger XLT with the 4.0 L and it's 4wd. For the life of me I can't figure out which gas tank I need to order. I know I can just drop the tank and compare it to...

Im rebuilding a 4.0 OHV and can't find any cam gear bolts or a new crank bolt for the engine. Do you guys know where I can find them? Rockauto, ebay, amazon Iv'e tried. If not, then red loctite on the cam bolts and blue on the top of the crank bolt(near the bolthead)? I tighten the crank...

My 1996 4.0L OHV has a slight fuel smell after adding gas. I can smell the gas from the cabin with the windows closed. I currently do not have a CEL on. What are some common areas to check for a fuel leak. My fuel lid is tightened down good (maybe its old and not working?) How dangerous is the...

Hey everyone, I just have a quick question. I found this broken piece when I was removing the valve covers as part of the process of replacing the lower intake manifold. I'm not sure what it is. I found it where one of the oil drains is for the cylinder head closest to the drivers side. I don't...

I'm looking to do a full rebuild of my 2000 Mazda B4000s transmission, it's got the 4.0L, 4WD, M5ODR1 trans, the case is spotless, but the guts are trashed, I know the bell housings are different for different engines, but can I take the internals from another M5ODR1 of a different engine and...

My son’s 2002 4.0 dohc ranger develops a nasty timing chain issue today. I found a motor out of a 2001 ranger with 105,000 miles for $1300 bucks. That’s cheaper than replacing the timing chains. my sons truck is an automatic and this motor came out of a manual truck. Is there any surprises I...

certain 4.0’s in the junkyard, specifically 1990 and 1991, have a MAP sensor (and the MAF sensor) and a plug for it on the wiring harness. in every picture i see of a 4.0 with the MAP the vacuum line to the sensor is not even hooked up and has a small white piece on it. furthermore, i took the...

I was wondering if anyone had a PDF or some sort of copy for the removal. Drive and Reverse went out, 1st and 2nd gear work though. Would appreciate tips or tricks if not. Thanks!

So, 1994 Ford ranger Splash 4.0 4wd auto Got it pretty good price, kid loved it, big tires, lots of cosmetic stuff. Kids had it before us took out all the interior plastics pretty much including dome light, headliner, a pillar trim, visors, etc., put all kinds of crazy lights under it, in the...

Hey everyone, im having trouble trying to figure out whats wrong with my truck. It is a 99 ranger with a 4.0. I have had the codes P0171 & P0174 now for awhile and it does this weird idle like its flooding after about 10-20min, I have had to reless fuel pressure a couple times when it was hot...

I have a 1986 ranger with 2.9 and 5-speed manual trans. I am curious about swapping in a new more powerful engine. Will a 4.0 be the easiest swap and if so what year 4.0 should I be looking for? If its not that much harder to go 5.0 v8 then I may do that but I am not experienced here and will...

I have a 1997 ford ranger 4.0. The truck got hot on the way home one night and was out of water. It had been using some water. So I did a pressure test and would hold pressure at all. I pulled the motor thinking it had to be a cracked head took heads in had the pressure checked and no cracks but...

new piston rings are going to be installed here soon as well as some other bottom end things, what break in oil would you guys use for this?

i really need this piece to complete my swap. can’t find one anywhere

i have got a complete 1999 4.0 ohv with harness and all accessories for my 1990 ranger and i don’t know all of the differences between the two (pre and post 1993/94) i already know a few of them such as the aluminum intake with no egr which i’ve already got from the yard, the wiring harness...
