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

Yeah, but you really don't want to go the cheap route when you do your plane.

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.

It's got 145k and its a manual. It's got newish synchronizers and new tie rod ends that you can actually grease, new clutch at about 100k, but I tow a trailer with it. In my area used small trucks command a bit of a premium but let's say I could buy the running version for 1200.  I'll take the valve cover off and do the leak down. My feeling is that if any of the valve train is badly worn I'll be spending 500. Does this sound right for head rebuilding, gaskets, timing belt?

a quick wiki shows the 4D55 engine has a timing chain not a belt so I'd imagine it would be fine at 145k, as should the valve train. I dont know that engine but 145k isnt alot for a diesel assuming its been looked after (ie. regular oil changes.) *

Do you guys have Haynes Manuals and is there one for that truck? I wouldnt do much more than changing plugs and filters without one, they are brilliant.


* edit: I thought you had the 2.3 diesel, if its the petrol engine there is a Haynes manual for it - buy one! And if it has a belt, definitely change that too :aok

 i'm pretty sure that ford didn't chain any of the 2.3 liters back then. probably the diesel, but i don't recall having ever seen a chained 2.3 gas eninge.

 regardless of mileage, if the thing's been setting for THAT long, i'd replace that belt.

Pemb I hate to say that you can rebuild the head, gaskets and timing belt for $500, because I don't know what kind of shape it's in, or what your abilities are. I don't mean that in a derogatory way, but not everyone has done a valve job or has the tools to remove and check valve springs etc. A cam and followers will run you around $250 so with head gasket set and timing belt you're pushing $450 right there. If any of the valves are burnt, the guides are worn, or you need to replace any of the valve springs or keepers that will push it over the $500 mark. You might check into a re-man head and see what they run in your area, If you can find one. Best thing to do is go ahead and do your leak down test and go from there.
I did my sisters pinto in the mid eighties and I had to replace the head because it was cracked. She swore it never got hot but it only had idiot lights and she did drive it home.  :huh I still have the special head bolt tool that I have never used since. Looks like a giant torx wrench.

Do you guys have Haynes Manuals and is there one for that truck? I wouldnt do much more than changing plugs and filters without one, they are brilliant.

Holmes the diesel version of the ranger is rarer than hens teeth, at least around here, so I'm pretty sure he has the gasoline engine.

Personally I hate the Haynes, and Climbers(sp) manuals. Not sure if they are different on the other side of the pond, but everyone I have ever had always has passages that say something like "this job is beyond the average enthusiasts ability, and should be taken to a qualified service technician." I want to know how it should be done and not that they think I should pay someone to do the job for me. So I stick with Chilton manuals. If you can find them MOTOR, or Mitchell manuals are what the professional shops generally use. I know that MOTOR has combined with ALLDATA and they offer their manuals online, but iirc they are still pretty spendy. Not sure if Mitchell has an online source or if they are even still around. The standard non pro Chilton should cost around $30. You can find them online for less, but after paying shipping it still comes out to about $30.

Step 1  get your ratchets out
Step 2  set them to loosen
Step 3  have fun and tear that rascal down.

Serious, why are people so scared about ripping into engines, especially with information available through the net at your fingertips.  There are no secrets when it comes to motors, crack it open and take a look.
