I found this guy at my school that said he'd sell his 81 4x4 luv w/ a 1.8 for 215-300 USD. Well me and my dad, whose's pretty good at the luvs and p'ups, went to go look at it and the guy says when you crank it, it surges, then eventually idles down and then shuts off, unless you push the accel. some. Well the problem is most of the vacume lines are missing, and i beleive the EGR valve as well... Should i get the truck and hunt down the valve and run the vacuum lines?

If you need smog stuff, check around to see if any junk yards have your missing emission pieces. Vacuum lines are like 50 cents a foot so that's a pretty cheap fix. If your hood doesn't have a diagram then you can find one on this site.
If you're not worried about emmissions, cap off all unnecesary vacuum lines. The surging is probably a problem with your carb, (if replacing vacuum lines doesn't fix it) the hitachi's kinda suck. If you don't need emissions' I would just drop the hitachi and buy a weber carb.

If it has a couple vac ports open and uncapped that would explain the surging and not wanting to idle. Sounds just about like what my trooper did when I first got it. The mixture control valve was bad and leaking off vacuum like there was nothing on that 1/2 inch vac fitting. It could have carb problems, but without knowing just how well someone capped off those lines I'd put my money on that being most of the problem.

Sounds like a pretty good deal if the sheetmetal is solid and straight. I've seen a truck with a blown motor and good bodywork bring more than $300 in more than one case. This sounds like just something where you need to back track and fix someone else's mistakes.

The only body panel that's rusted is the right panel of the bed, a small hole and a big rust patch... macco will fix it for pocket change... i got connections...

There's a few other things missing as well, the air switching valve, gas filter(for the vac. lines) maybe the mix. control valve, and the therm. vac. valve has a glued-on vac. hose stem...

And yeah there's a junk-yard with 3 isuzu trucks w/ gas engines... 2 w/ the heads and up removed and 1 with everything cept the valve cover and some valve springs.... and the air cleaner.

with all that stuff missing, i think thats why it's surging.

if you have access to a couple trucks, go for it man

Well it's not exactly surging... it's idleing EXTREMLY HIGH, idles down then shuts off....

I beleive Narcisist had a simimlar problem with his truck where he had to "feather" the gas, which is what you must do to this truck...

Get this, i might get this truck just for giving the guy a rimmington target master .22 bolt action... i've only shot it about 20 times

well, i've had the truck for about a month now and we've put a halve re-built carb on it. Runs MUCH smoother... but it still shuts off... we've adjusted the dist. so we didn't have to push the accel. as much to keep it running.... we did a vacuum test on it and it doesn't have vac. when we let off the accel. but we rev. it and the vac. goes up... so then we took some starting fluid and sprayed around and found out our vac. is leaking through the intake mani. gasket. which has slipped part-way out, so now we've got that to change... we'll prob do that after T-day. hopfully we can hurry and get it changed b4 winter...

One ? though... are there pegs that hold the gasket on the head so you can slide the intake on?
Any tips to get the job quicker also? Thx...

The studs should stay in the head when you undo the nuts that hold the intake manifold on. Hang the gaskets on them and put the intake back on over it. Only trick I have is to be sure to clean both the intake and head very well. I used a razor blade to clear off the old gasket remnants. I followed that with a light going over with 400 or 600 grit paper on a sanding block. I would not do the sand paper on the head side if you don't have it off the motor. Too easy to get grit in places you don't want it. I put on a Felpro gasket with no sealers and it has been holding up just fine for me. On the rear of the manifold there should be a tiny hole that goes to the water passage in the head, clean the gunk out of it and you'll find it easier to burp the air out when you refill the coolant.

Oh yeah, disconnect the battery for sure. It is really easy to short the starter on trying to reach some of the lower nuts to get the manifold off.

Do a search here for EGR or EGR pipe, that will probably be your biggest challenge really. Remove it at the exhaust side or the intake, which ever it will allow. Niether one is very easy.

my dad found that out the hard way....

My luv had a hard time staying running and i narrowed it down to my fuel pump, which was a retarded thing to do becuse it still didnt run much longer, so i had to replace my fuel tank, but in order to take my tank out i had to take off my bed, those beds weigh a hell of a lot more than toyotas. but what im getting at is check your tank, there was a lot of rust in the bottom of mine.

Currently no more luv's... But in search of one!

i had that problem it was weird i turn my key to on you here the fuel pump you turn it so it will run it will run high than die my problem was the fuel pump wouldnt stay on when it was on running for the key so i got a electric fuel pump and ran a toggle switch so when you start it you flip that switch wait a couple seconds push on the gas and fire it up runs great had this like this for 6months and still works fine.

it's not the tank that's the prob. it's just the vacuums being sucked away... to bad i can't get the whole engine and everything from japan... they didn't have this crap over there i don't think...

oh yeah! Does the header for the 81 gas have the EGR line fitting? (w/e you call it)

I've yet to see a header for a LUV with the EGR fitting. Pacesetter headers don't have it, the could of Hooker headers I've seen don't. A header for an Isuzu 2.3L might work and has the EGR bung, though the ports on the head of a 2.3L are round instead of squarish. I don't know how well they'd line up, even though the spacing and bolt pattern looks right. I'll let you know if/when I get my 2.3L torn apart.

good news! We've got the new gaskets on... but kinda had to jimmie-rig the starter sil. "hot wire"... took us from 9 am to 6pm to finish, but we're gonna try to run it sunday. just to let the silicone set and cure... then were on the hunt for polution control thingy-ma-jigs!

IT RUNS!!! heck yeah! it'll even spin tires, at 262k miles! but there's one more prob. we've changed the plugs those are good, wires are good coil's ok... carb runs great, but now it idles up then idles back down, then dies!, So we just hold the gas down till it gets warm enough to satay runnin but even after that it idles up but after 30 secs it idles back down,just a tad but you can still hear and tell we may rebuild the old carb and swap'm out... 800xl Got a solution?!

Oh yeah, does anyone know if the older luvs have the following?
Back press. transducer
vacuum control valve
and a thermal vacuum valve

?????
