Turns out a 'modern' 4.0 OHV 4.0 Ford is based on that engine and will bolt up in place of the old ones. I'm thinking about getting one of those and a T5 out of a Mustang so I can have overdrive and more cubes.
It should be a fun swap that will be cheep cheep. (plus my TVR's 4 speed was never offered in the states so it might be worth a chunk).
I had a '92 Ranger with the 4.0 Austrian pushrod engine if that's the one you're talking about, It was a stout little engine. Ran very well and surprised a lot of people off the line. Put 200,000 miles on it before I traded it off. Loved that little truck.
That would be the one. Ford has two 4.0 V6's. The older OHV like we're talking about and the OHC which is a POS. That's he one in all the Explorers with ''blown'' engines that rattle.
It's a really screwey design. Most OHC engines have a seperate head for left and right due to the cam drive on the front of the engine. On that Ford, the heads match so one head has to be driven from the rear. So they put a jack shaft where the cam used to go. That way one bank gets driven from the back of the engine. The front of the engine has two changes, one for a head, and one to drive the jack shaft.
I used the special tools one time to replace the chains and time the cams. It was a MAJOR PIA, and the engine was on a stand. There's no way I'd ever attempt it with an engine in the vehicle.
I actually thought about buying every Explorer I could find with loud chains to flip, but that repair is just too messed up! lol
Yea, I tried for a year to find another low mileage Ranger with the OHV engine and couldn't. Test drove the OHC but never liked it. I ended up buying a new 2003 Dakota with the 4.7 V-8, BIG MISTAKE. Constantly had to fix nit picky problems. By the time it was 3 years old I had replaced every vacuum line on it and ended up having to make my own thermostat housing out of aluminum, the plastic ones kept leaking. Now I have a 2013 F-150 SCREW with the 3.7 normally aspirated engine and I really like it. Screaming little engine and gets decent mileage.
Part of the reason I got rid of my Dakota was the mileage. You'd think a computer controlled, fuel injected 287 cu.in. engine would have gotten better mileage than 16 mpg. Crap, my '65 GMC with a 283 got better than that. Dodge cheaped out by using old style copper core plugs that had to be changed every 25K. I think they scrounged all the old hoses that they could find and put them on my truck because I ordered it instead buying off the lot. No more Dodges for me.
