1986 ford ranger engine question
« on: May 15, 2013, 07:37:04 PM »
It is decision time, my 86 ford ranger 4x4 is on the bubble. It's been taking up space in the garage for a year and I have to decide what to do in order to maintain domestic tranquility. Something bad happened to the motor, 2.3 FI. Could be just a head gasket could be worse. No compression in the two center cylinders, they act like they are connected if I recall. Was going to do a leak down test but the truck got buried with crap so I have to un bury it. In the mean time I thought I'd ask for advice. The thing is if I don't just sell this thing, if I'm going to take the head off I feel like for the effort I might as well take out the whole motor.  The last time I had this kind of problem back in 1989,(different truck,) I first got a junkyard motor which burned oil so I took it back and then rebuilt the original. It was the only time I rebuilt an engine and what I discovered was I was paying a pretty big percentage of what a rebuilt motor from a mass rebuilder would cost so that I could use plastigauge and I guess know that the parts were good. My question would be does anybody know a good ranger forum? How new a used engine would fit? Are any of the mass rebuilders any good?  It was a work truck so it's nothing fancy but it,s grown on me to the point that I hesitate to have it towed off to the smelter.

Ok...keep in mind that I'm a race car guy: if it was mine and the body is in good shape, I'd 302 it with a carb.  Many of those out there in good shape.  On the other hand, if you just want to do a 2.3 replacement used wise LKQ, I believe they offer a small warranty on the part.  Also you could try Autozone/Advanced for a crate 2.3L for about 1500.00 with a 3yr warranty for the long block.

 those 2.3's are great engines. they suck for power, but they're generally very reliable.

 what you describe sounds for sure like a blown gasket, or a cracked head. before deciding on anything, pull the rocker cover, and remove the cam followers on the cylinder you want to check the leakdown on. find where the pressure's leaking out. through the crankcase....wasted rings or cracked/broken piston. through the exhaust or intake....something wrong with the respective valve. through the cylinder next to it.......pull the head.

 i don't think they went to dual plug in 86, but they did(i think) sometime during the use of EEC4. if so, you can swap in a dual plug 2.3, with the accompanying wiring, and ECU, for a little better mileage, and a little better power.

 of course, the other thing that you could do that would be MASSIVE fun......find a wrecked fox body mustang that runs. take the engine, drop it in, and install the v8 EEC4 system. there's only 7(if i recall correctly) wires that you need to tap into the vehicles stock wiring system to make it work. remember...if you put a v8 in there though, you're gonna have to upgrade the tranny, and the diff.

 or you could sell it as, 'cause there's probably a kid out there that'd want a 4x4 that he could work on.

usual sign of a blown head gasket is oil/coolant mixing - check the coolant reservoir for oil on the surface, and the head for mayonnaise. You should see it inside the oil filler cap if its on top of the rocker cover, or remove the rocker cover and it should be everywhere.

Be best to buy a crate motor and use your old stuff on it . Just have the head's rebuilt and be done with it . What I have done with my last two truck's . Then you will have a bad as motor with 10 overs in it . I would put a 4.0 in it while I was at it but you have to go find some used head's to have rebuilt .

 ya know? i hadn't thought v6 route........it would make a SUPER interesting swap to put a 3.7 liter from a wrecked s197 stang. i think it'd be really tough to work EEC5 into the old wiring though......

EEC4 is a "stand alone" system, and can be wired in fairly easily. you need to spend time going through the wiring diagrams is all. it's the EEC5 i'm not sure about.......

$100 for a gasket set and a coupla hours work vs $1500 for a new engine and a coupla days work ... I know what I'd do.

Sounds like a blown head gasket. You can have the head gasket blow out between the two center cylinders without getting oil water contamination. You didn't say how many miles are on the truck, or if it's a manual or automatic transmission.

I would pull the head and check the condition of the cylinders, and have the head checked for cracks. Also check the cam for flat lobes and worn followers. If the only issue is a blown head gasket you will still want to replace the timing belt. You should be able to do that yourself for less than $200, Also take into account that even if you do put in a rebuilt engine the rest of the running gear is still twenty seven years old. Normally the next thing to go would be the clutch and/or transmission especially if you put in a fresh engine.

We are talking about a nearly thirty year old work truck that's been sitting for a year already. In running condition the truck isn't worth all that much. Doing a google search I found several runners for $1k or less.

You're forgetting about the new seals and bearings that come with the long block.

I would think taking the valve covers off might be a good start and go from there. Maybe just a case of sticky valves, if lucky. However, the two cylinders acting together could be a bad thing.

I read $1500 for an engine and I weep when I know it'll run me $35,000 when I remoter my plane
