I need some advice; I have a 1988 Trooper. A few months ago I started it up and clouds of water vapor came flying out the back.. I am pretty sure that this means a new head gasket?? My deal is I love the Trooper and my kids do to.. Do I put the money into it to have it fixed first off.. and if so should I buy a new head and put it on myself?? A new cylinder head with gaskets is like 5-600 and some man hours by me.. or should I let the shop do a head job and valve job the shop wants 1500.00?? I have never done a head gasket, but have done some cam work and most every thing outside the engine. I recently replaced the shocks, brakes, fuel pump, fuel filter, belts, starter, alternator, battery, vacuum hoses well most hoses.. It's a hard choice for me I only have 1500. to put into it and my family is very dependent on this vehicle... I have read that you should buy a new head and it will never blow again.. The guy at the shop says no prob. bro. you don't need a new head... Please help; I am lost and want to make a good decision... Ty

To Ty: 88 Trooper II head replacement.
Do yourself a favor and buy a new head. I just replaced mine this past week and the cost was about 500.00 and two days work. E-mail me if you like and I can give you more details on how to accomplish the switch with the least amount of effort. firstname.lastname@example.org

I just bought a 88 Trooper with the 2.6. The #1 cylinder only has 30 lbs compression, but the head is brand new. Does anyone have any ideas? I would greatly appreciate your help. Thanks.

I have a 89 Isuzu Trooper 2.6 L.
I bought it almost 5 1/2 years ago and it runs great.
175,000. Now the problem... it starts but dies in a few seconds.
Now if I hold the pedal down to 1,500 rpm to warm up, it idles fine. What should I do to fix this? Vacuum lines maybe...?

Need help with an Amigo First Gen that I am building.
I have a Trooper 2.8 motor and tranny that I was using to install in my Amigo. But I am wondering if I should install a 3.8 motor adapted to the 2.8 tranny and install it?
Any help would be appreciated.
Any ideas if I use a Grand Prix motor 3.8 V6, how would the electronic fuel injection work out? What might I have to do?
Any info or suggestion about the fuel injection part? Thanks

I have a 1988 Isuzu TrooperII and the 4th cylinder only holds about 28 lbs of pressure.
I believe it's either a bad gasket or valve.
I don't know what it can be.
Could it be the spark plug wire?

I have an 88 Trooper II with 2.6, 278,000 miles. Runs great, just leaks oil very bad. Looking for the best place to buy a spare engine just in case?

I have a 1988 trooper and am going replace the head gasket in a few days here. There is a gang of gaskets in the kit and I have a 4 inch thick manual so far so good. Is there a list of things I should do while I have the head out??? And are there any parts I can add for better performance and more power???

I have an '89 Trooper with 2.8L V6 and 5 speed manual transmission. Apparently the transmission was low on oil as it failed going down the turnpike. Trooper has only 124,000 miles on it and repairs will be about $2200 dollars for transmission rebuild, new clutch, new rear main seal, and exhaust work to put it back together. I have had the vehicle for about 15 years and really like it's ruggedness and style. Do you trooper lovers think it is worth that kind of money to repair a 20 year old Trooper?

So I need some scoop on the 4.3 liter conversion. Is it true the 4.3 won't bolt up to my stock 5 speed tranny. I have not even begun to research it but I would think someone has to make an adapter plate or something. Any help would be nice. Theres gotta be someone who has done this conversion before.

I just bought a 1986 Trooper II LS (4-cylinder 2.6) with 97,000 miles on it. It runs great and looks even better. I'm very happy with the truck, except for a small oil leak on the main oil pan. I was curious if anyone has had this problem, and how much they spent to remedy it? I'd be happy to send some pictures if you want to see it. It really looks great!

I just bought a 1990 Trooper II with the 2.6 ltr. and 5-speed. I bought it from a family friend for $500. I love it so far, and can't wait for trips up to the trails! I sold my Vanagon to pay for it and start adding all sorts of goodies. Does anyone know a one-stop parts & accessories supplier for Trooper IIs?

Old Troopers are just that - old Troopers. They didn't get that way because they died in their early years. As a career mechanic and longtime Isuzu owner, I have come to some conclusions that may or may not help newer owners of the 2.6 Troopers. First, accept that your engine puts out about 110 HP at 3500 RPM in a 3800 pound rig and drive it as such. That will help you. To help your Trooper live longer, replace the entire exhaust or as much as you can with a freer flowing system. Have all of the emissions system components checked for proper functionality. This is critical to proper ECU function. NEVER OVERHEAT. Clean your MAF yearly. Check pigtail connection to pressure sending unit if gauge pressure wavers, and make sure all sensor connections to engine electrical system are solid. Respect the Trooper; it'll take care of you.

I think most great parts for the Trooper are in Australia. I've heard you can put turbo set up off an Isuzu Impulse on Trooper, but you need everything - injectors, pump etc off the donor Impulse.

I have an Isuzu pick up 1990. I was driving yesterday and I felt the power cut. After checking it, I found that the camshaft has been severed in the center. I replaced it a few months later and the same thing happened again. Can someone please help me? My email address is firstname.lastname@example.org.
Thanks in advance.
