87 Trooper II 2 door DLX

Postby Torquemonster » Mon Jul 11, 2016 11:32 am

Ever since my dad brought home his first Trooper, when I was 4 years old, I knew I wanted one. Well 16 years later I finally found it. My Rodeo was nice but I found when I went camping I filled it up quick.

Heres a short speclist
DLX trim
2.3
5 speed
No rust on the body or frame
Mileage getting up there (214k)
Doesnt currently run

The seller claimed it had carb trouble, but all the intake bolts were loose, and thermostat housing was off, no oil or coolant in it... It kinda looks like someone was prepping to put a headgasket in it. But Im keeping my fingers crossed.

Well since its at my dads place for now hes been fiddling with it a little. He put everything back together, put some water and a bit of oil in it and put some fuel down the carb and she ran for a few seconds. However, before he did anything he checked the dipstick and it had alot of fuel in the crankcase. He said he drained a few liters out of it. On the drive home we had to stop shortly after loading it, the fuel line was unhooked and it was siphoning gas out. We plugged it off and kept going. I suspect the diaphragm on the fuel pump is torn, and while it was siphoning gas out it was filling the crankcase.

If the PO was trying to change the fuel pump, that explains why the intake was mostly unbolted, since most manuals say you have to remove the intake. Im gonna try to find a pump locally, but I might also put on a cheap low pressure electric pump in.

Nice find. Hopefully it will be an easy fix with a new fuel pump.

My 86 from way back when did the same thing. Not too tough a job. Nice rig! I can't wait to have the budget and time for a new project. It will definitely be a Lwb 2 door.

Thanks! Im gonna try tonight, I sourced an oem pump locally that didnt cost an arm and a leg.
I didnt really have the budget for another project, but I found this for real cheap and I had to have it. I paid $400 and Im at about $450 in fuel costs and trailer rental going to look at it and then dragging it home.

I bought my Trooper for $700 as a "cheap" project. Over $3,000 later, I have a $1,500 Trooper. :roll:

Yep, that's most of us. As to the fuel pump, you do not have to remove the intake. Just remove the right front wheel and inner fender splash guard. It's hard but do-able. You'll need to put the engine on TDC to take the pressure off the pump push rod. That puts the fuel pump push rod on the flat part of the cam and makes for putting the pump on without actuating the diaphragm. Also 2 gaskets are required as there's a spacer there between the pump and engine. There's four ports on the pump. The one on the left is the one from the tank. The bigger one on the right goes to the carb and the smaller one on the right goes back to the tank as a return. The one on the top is just vented to the atmosphere and doesn't require a connection, but I have seen a short hose on it in case of a leak the oil or gas will not get all over the lower part of the engine. On a good pump there is no fluid that will come out of that vent or drain line.

Im not too worried about my overall investment with this thing, Ive been looking for one for a long time and I have no intentions to sell it. Hell its been 16 years in the making haha.

Yes my plans are to go through the wheel well. I saw some posts on here saying its not necessary to remove the intake. Thanks for the info on the ports! I havent actually looked yet to see if mine are still hooked up, but if they arent now I know

It lives! The hardest part of changing that fuel pump was removing the EGR fitting from the bottom of the intake.

It needed a little fresh gas down the carb to get going but after that it ran (for the most part) off the stale crap that was in it. My dads gonna drain the tank and refill it for me. I think it might be tuned a bit rich too, but its hard to say without fresh gas in it.

The rear driveshaft was out of it when I got it, and I just realized its missin the flange at the rear axle. I need to find another flange so I can move it out of my dads yard

Well, while it was running wendsday it wouldnt start saturday, even with fresh gas in it. I tried to pull the carb to do a proper clean, but atleast 2 of the nuts were nearly impossible to get at with the manifold on the engine (Well maybe if I find a 12mm crowsfoot...)

What I ended up doing is removing the float chamber cover with the carb on the engine (It was super easy to get at) and giving the workings inside a good clean.

Needle valve looked ok, fuel inlet screen was good, float was ok, but this was in the bowl
Image

Ew. Cleaned all that crap out, removed the jets and of course they were plugged. Cleaned those out and re assembled and it started!
Image

Re did any split vacuum lines and its purrs above 1000 rpm. If it drops below 1000 rpm however it sputters and dies. Ive been adjusting Idle and mixture but cant seem to solve that issue. The wire for the float bowl vent solenoid was ripped out, maybe its that? Who knows...


And while I couldnt find a driveshaft or flange, I noticed the flange on my spare Rodeo driveshaft will fit on the 10 bolt. Ive dropped it off at a driveline shop today, they are going to cut the end off of my spare Rodeo driveshaft and weld it to the Troopers driveshaft. Its going to be the cheapest and quickest option, plus its a larger U joint which is an upgrade I guess...

So after fiddling with that carb and checking all the vacuum lines and still having it run like crap I ditchecd the stock carb for a 32/36 Weber. Holy crap, 2 of the nuts on the carb, closest to the valvecover, are nearly impossible to get at without a crowsfoot socket. I had one, but it wasnt fully open, it was more like a line wrench. Having driven 30 minutes to work on it I wasnt gonna give up there, so I used a hammer and screwdriver to remove those nuts. Wasnt pretty but it worked.

Boy, the throttle shaft bushings on the stock unit were gone. Had atleast 1/8th inch of play, no wonder it ran like crap. Of course it started right up with the Weber, didnt even need to tune it, although I might fatten it up just a hair. I might look in to an air/fuel gauge...

Now the only problem is the check engine light is on constantly. I havent hooked up the choke yet, and the IAC motor is removed, and anything else electrical that was on the stock carb is unplugged. Maybe if I plug the IAC and choke back in it will go out...

Well, its about time for an update. Ive had it on the road and driving it for about a week now. So far hasnt let me down yet, the 2.3 with the weber on it feels almost as peppy as my tired old 3.2 did in my Rodeo. And Im getting much better mileage, with no lifter tick! However I am chasing a stumble on acceleration with the weber, and an oil leak has appeared from somewhere under the timing cover. My drivers front footwell is also filling with rain water, Im not yet sure where its coming from. Planning on adding manual hubs, and swapping the open 10 bolt for a 12 bolt Limited slip axle

I think its the firewall, cause the doorpanels dont get wet at all. Im hoping all it is it a bunch of crap caught up in the cowl or a missing firewall grommet

Well, I tried to go to work today but came home sick. In between visit to the bathroom praying for death, Ive done a little work to the Trooper. Sprayed it with a hose and went looking for water. I learned 2 things:

1) Yes, the vent windows leak, but they arent causing the puddles in my footwell. They leave a considerable amount of water on the doorpanel and I would have noticed that.

2) The leak appears to be coming frm this bad boy
Image

And his brother on the passenger side
Image

On the inside firewall, both of those gromets have rust colored rings around them and water trails leading down to the footwell. Also the carpet underlay glued to the firewall was completely waterlogged.

Now decision time, replace those gromets, which I assume would involve either slitting the new one to slide it over or finding the end of the harness and stretching it all the way down, or cleaning the existing ones and packing them with sealant?

Those may be where the water is entering, but the problem is more likely a clogged drain port somewhere above those grommets, which is allowing water to back up and drip onto them. Clogged drain ports are common, and will lead to all sorts of ugliness, which typically manifests itself in the floorboard of the front seats.

Agree on the drain ports especially given how much water you are seeing. Good looking 2 door LWB, definitely worth the time and energy. The firewall grommets get funky but still work pretty effectively, I wouldn't change them until you get done wiring up everything you are going to put on the front of the truck, driving and trail lights come to mind. There aren't are a whole lot of places to run wires from outside to inside and it is amazing how many wires you can stuff through that grommet.

Well Ive had a look, and there doesnt appear to be any drain holes on the firewall lip, right above those grommets. Maybe that was a common problem on the pre 88 trucks, and fixed post 88? Just my wild thoughts going again...
Regardless, I used some weatherstrip adhesive around the grommets, and it rained last night, so far no water...

So I got in the truck this morning to go to work to find more water in the footwells. So clearly not the grommets. Im on my lunch and its raining, and I was lucky enough to be able to see the water trail coming in. From the interior under the dash, to the left and near the top of that grommet, is a corner where a lip on the firewall meets the inner A piller/kick panel, and the water is coming from there. Theres seam sealer across the lip and the A pillar, but none in the very corner. Best I can tell is it relates to this corner in the engine bay
Image

If your standing infront of the truck, thats to the right of the brake booster, in the corner where the firewall meets the inner fender. Theres a lip there. Im going to confirm that thats the hole by inserting a small piece of wire, like a guitar string or something and seeing if it goes through into te cabin.

Now, if this is my leak how would I fix it? There isnt any drain holes on that lip near this area, should I make some? Should I apply some seam sealer in there? Judging by all the rust that was in the drivers footwell its been leaking atleast 8 years. Maybe the factory sealer dried up and fell out? I dunno...

Well, I did more digging at work and found the source. Water was running down into the crevice in the picture, down into the fender well area to another lip, and thats where the leak is. Looks like the seam sealer may have contracted slightly. I gobbed some RTV in the corner, supposed to be dry the next couple days, so it should be able to set before the next rainfall

Well so far no more pools in the footwell.

A couple weeks ago I ordered some 31" Geolanders, and they came in yesterday. My boss owed me a favour so onto the lift it went when I got to work today

That looks better

Also investigated my heater controls more. Sure enough the vent control cable is loose.

So the lever just pushes or pulls the entire cable, instead of sliding the cable in the housing.

Thanks!

Last night I replaced the O ring on the dizzy, and tonight I replaced the valvecover gasket. Set the valve lash and retorqued the head while the cover was off (just cause I dont know if the head was ever done or not)

When I got home my parts arrived from rockauto. Theres a dizzy cap, rotor, and plug wires there as well as a water pump and timing belt kit. I ordered the timing belt and water pump about a week later than the ignition parts, but they both arrived today. Seems like the more I drive it oil will start to leak from somewhere new. The first few days I drove it there were none.... There is oil leaking from somewhere under the timing cover so I figured Ill change the timing belt and the 3 seals the kit comes with. Then all thats left is the oil pan and rear main I believe, which can wait till I do the clutch, whenever that happens

There is oil leaking from somewhere under the timing cover

I recently went through that on my 89. Replaced the oil pump seal and "0" ring. And the front main seal. Also while I was there, the filter housing seal. Still leaked. It was a small crack in the front main seal retainer, so had to do it all over again, so check the seal retainer integrity. I first saw the crack in the picture I had posted asking for advice about what I thought was a grove in the crank itself.

Page 6 of my build shows a picture of the cracked retainer
