Did you miss my post on having 2 almost identical 2000 explorers with 4:10 and 5 spd autos and the only variable was 15" wheels over 16" and leather seats? Heck they were both even the same color, white with gray cladding. I don't think you can get a better comparison than that. I still say OHC>OHV anyday of the week.

I couldnt stand the RPM range on the SOHC, my 05 didnt really pull till like 3500 and my 2000 OHV always pulled best 15-2500.

Then something must have been wrong with your SOHC engine. The OHC and SOHC engines both have the same torque at 1600 rpm. Below that the OHC has a little more torque and above the SOHC has anywhere from a little more torque to a lot more torque. There is nothing on the torque or hp curve that indicates there is anything special about 3500 rpm with the SOHC engine.

My SOHC engine pulls reasonably well at 2,000 rpm but likes 2,500 rpm better.

You can get to it through the wheel well. Very easy. Your friend got his *** handed to him.

Ill happily change both of them for you and only charge you 8 hours labor instead of 11-20 hours to swap a new motor out.
he is the mechanic doing the work on it... told me some plastic part broke and they called Ford and they told them only way to fix is to replace the long block

I never drove an OHV 4.0, but I did drive an SOHC in an 05 ranger, and I was impressed. If I get another ranger after this one, I would get one. From what Ive heard, the ones after 03, or 03-up were supposed to be better as far as tentioners go.

Hi but the chain possition doent matter. As long as crank is tdc on comp stroke and cam is same, gears and chain possition does not matter. Lots simpler than timing a Honda belt.

You have a SOHC in your 2011 4.0L Ranger. They started using the SOHC 4.0L engine in the Ranger in 2001. The 4.0L pushrod engine became available in 1990 and the last year was 2000.

After reading this post and being a recent owner of a 2004 ranger xlt 4.0L 5sp manual 4x4, what is the difference between the two engines? Which one came with 2004? How do I tell which one I have? On a nother note, what does the XLT mean. I don't have elec mirrors, windows, or any creature comforts that I would expect in a XLT(extra limited ?)

You have the SOHC. All rangers from 2001 on that came with a 4.0 got the SOHC.


XLT is just the trim package. Rangers never really had defined options for certain trim packages. Some had a few common options, like edges got color matched plastics, or xlts got chrome bumpers. But for the most part, it depends on what the truck was ordered with.

So by 2011 did Ford "fix" the timing chain issues w/ this engine? With regular oil changes and normal use, I'd hope I'd get 200,000 miles out of this truck w/o have to get into replacing timing chains, gears, & tensioners.

Just wondering what the track record of the final generation of this engine is like?

It's at 75,000 miles now and only issue its had is one of the cat converters had its insides come apart @ 68,000 miles. When it happened, first thing I thought was "major engine failure" - the rattle & noise was that bad. But I probed around underneath the engine w/ a screwdriver handle to my ear and very quickly determined the cat was bad. Short time later a code appeared and once read certainly verified what I already knew. And Ford replaced the cat under the emissions warranty.

2005 and up 4.0l SOHC were fairly trouble free, 1997-2004 had the timing chain issues, but once parts were changed they became trouble free as well.

^^^ This ... but if you want to get real technical about it, the early 2004 4.0 SOHCs are hit and miss, but the late 2004 engines are golden.
I had a 2007 Ranger with the 4.0 SOHC with 391,000 on the clock and it purred like a kitten just like a new engine because the oil was changed like it was supposed to.

2001 and earlier seemed to be the worst for the 4.0 SOHC. Many of those had problems. They still had problems in 2002 but considerably less. I changed my tensioners sometime after 100K miles just as preventative maintenance. The old ones were still good and I still have them as backups. I am at 213K miles now and the engine is still strong with no timing chain problems that I know of. My original plan was to keep it to 300K miles and longer if I can't find something suitable to replace it.
