will a 2009 4.0L engine 2x4 fit in a 2004 4.0L engine 4x4

 

I have an issue. I have a 2004 4x4 ranger 4.0 and It developed a loud rattle, and then on the way home started running really ruff, barely making it home. I pulled the engine, pull the front timing chain cover off, and sure enough, the plastic portion of the tensioner was gone and the chain had been loose and hitting the metal portion of the tensioner that remained. I then pulled the valve covers and turned the crank so the #1 piston was at the top, and the keyway on the crank was at top dead center, or 12:00. I then checked the slots on the cams to make sure they were parallel with the top of the heads. The right side is parallel but the left side looks to be at least a tooth off. How can this be when both cam timing chains, guides and tensioner are in tact? They both run off the jack shaft so how could one cam have jumped?
Also, the truck barely made it home. I
Can't see how, even with the loss of the tensioner, it would have caused the truck to run so poorly.
Lastly, from what I've read all 4.0 ranger 4x4s should have a balance shaft, but mine doesn't.
Need some feedback. I can't afford to replace all the timing components and reinstall just to find out the cams were correct, and by leveling the cam slots to the heads I screwed up the timing. I realize I've thrown a lot out there but any help would be greatly appreciated.

 

So I just put a throttle body spacer on my 2006 ranger 4.0 and I thought I had it on backwards so I turned it around but I am still getting a vibration at 60 not as bad now but still there and very noticeable I am running a superchips tuner and k&n intake system any help would be appreciated

 

Hi
Just got my ranger in may used 160k seems sluggish and kinda under powered, and it get very bad gas milage 13 14 15ish. I was wondering if this is normal for rangers. Or if i should have the engine checked and tuned.
thanks, Derek

 

In my experience, no. Not normal.

My 2003 4.0 had full power up until 195000 with years of regular maintenance.

I would check the condition of a few things to see if the power may be resurrected

All the usual maintenance stuffs...new oil and filter, new air filter, new fuel filter, check the MAF sensor, check the plugs and wires, check the coils.

I once had a little hesitation in my rig, and when I ran through this list and changed the fuel filter and cleaned the MAF sensor, VROOM VROOM!!! Easy peasy.

Deeper, you could check compression. Lower compression could mean internal chaos. Cool thing is, you can find a compression tester cheap like 25-30 bucks at Harbor Freight or Amazon.

O2 sensors are not out of the question. I'm sure I've missed a few things that others may chime in with.

As far as mileage...I do get 14-16 in the city, so you're right there, but you no go-go. This might help you get your go-go back.

 

Im actually having issues with the computer programming/tuning for my ohv trans with sohc engine/ harness & computer need some advice

 

Hello - my son and I want to put headers on his 2003 Ford Ranger FX4 Level II - would doing so require us to change the truck's tune?

 

I wasn't aware that Level II was available in 2003.
edit: Just looked it up. 2003 was the first year for the Level II.

 

Is a handheld tuner the only way to tune my 99 4L OHV? I have a mod'd ODB2 to usb cable that I use to adjust parameters on my wifes Focus with the use of my laptop and the FOCCCUS app. Is there a similar app that would allow me to tune my truck via my laptop and mod'd ODB2 USB device?

 

Hi guys, just wanting to know, what are kind of spark plugs does my 1993 ranger need? its 6 cylinders, its not a 4x4, just getting to know it really
So any info helps a lot. Thanks!!

 

Bought a set of plugs and wires for my 2001 4.0 SOHC motor. Why the one gray spark plug boot while the other five are black? I thought maybe it signified #1 cylinder but it's not the longest wire.

 

I shouldn't address this because I do not KNOW but I believe it makes no difference.
I ASSUME boots come from the boot maker in varying shades of grey-to-black because you'll see wire sets with inconsistently colored boots in catalog listings.
How many miles on your 2001 4.0 SOHC?

 

I have 123,500-ish on it. Just got it from my father-in-law who know longer drives. Oddly enough, zero timing chain noise, even ice cold. Have no idea what may have been done to it before he bought it used from a local Ford dealer years ago.
Regarding the plug wires, I ordered them from Rock Auto. I went back and referenced the pic and it also shows one gray wire boot. Weird.

I realize this is an old thread.... but, I'm wondering if anyone here has information on a good tuner for the 4L OHV motor? Just trying to see what current information/recommendations are out there. I recently rebuilt my 99 4L with a few mods and looking to boost performance maybe just a little more over stock tune. Added 1.7 roller rockers, shorty headers, and gibson catback exhaust.

 

Superchips is mentioned above (post 353?). Contact them. Get prices and go to where they send you (websites etc.)
Look at almost all of leadfoot's posts.
The search function on these boards exist in name only so try scrolling around and see the charts and columns whiz by. Those will be posts on tuning. Stop there and read a few.

 

Thanks for the info! I've been searching for a while, just finding mostly outdated info and wondering if anyone knows of anyone doing current custom tunes for the 4l OHV (20+ year old motor). I'll keep searching and see what I can find. Have also done a little youtube watching on learning program tuning, which could be invaluable for me to learn... Give a hungry man a fish to eat and he'll be back tomorrow for another, give him the gear to catch his own and teach him how and if he isn't lazy... he'll provide himself with his own and leave you alone.

 

I have a 2000 4x4 Ranger with a 4.0 5 speed. It seems very low on power compared to my old 92 4x4 5 speed Ranger. Will a pair of Headers or dual exhaust help this truck and how will it effect the tune?

 

Is yours the pushrod motor? Sorry, just not sure when it changed to OHC...
I recently changed to headers, cat back exhaust, 1.7 roller rockers with hydraulic lifters, and new heads. I don't have a tuner on it but I know it's flowing more air than before and not throwing any codes. You probably won't notice any power increase if you just change to headers. With everything I did, there wasn't a huge increase of power so I'm hoping to get a tuner and see what that will do for a little more at the pedal.

 

yeah man 2000 was the last year for the old school pushrod 4.0. Just wondering what can be done to add some power to these motors. It's a complete dog compared to my older 92 4x4 Ranger...

 

I agree on the limited power. I upgraded my rockers to roller 1.7s with Morana racing setup, but still doesn't seem to have as much as I'd like. You can try his 1.8 setup but after all the problems I had with it I wouldn't recommend. Morana is working on a new rocker for this motor which I like but needs some details worked out with the manufacturer... Tom was lots of help with my project upgrading to 1.7 roller rockers and very knowledgeable. Now I'm looking to get a tuner, probably flashpaq by superchips, as there don't seem to be many options out there but pretty sure a tuner will give a noticable boost. Have not contacted superchips yet but planning to and get their input.

 

So I have an event on the 28th of April and I’m getting my first tuner on the 21st, can anybody help me tune my 4.0 2003 Ranger before the 28th?

 

You have no tuners in your town?

 

I think the closest ones are in mass which is a few hours away from me.

 

So, I have an 04 ranger 4.0. I just got the obd2 mx+ bluetooth scanner. I've seen some stuff saying I can use it to tune. Has anyone had any experience with them? What apps do you use? I'm specifically wanting g to fix the lean condition that causes shudders between 40 and 60 mph. I will be putting new plugs and all in it (just got it). The odometer says 328,000 miles but I'm pretty sure the engine has been rebuilt or replaced. It has plenty of gitty up. Will spin the tires pretty easily. Just that damn shudder. I'm thinking about eventually maybe adding a turbo bit that's future dreaming lol. Tha KS in advance I'd anyone actually responds to this ancient thread lol
