1991 Mitsubishi Montero LS 3.0L naturally aspirated


Good car, I have faith in it


I bought it with a couple of busted piston rings, knowing I'd have to rebuild the engine. Had the engine rebuilt. But one of the hydraulic lifters seems to be making a ticking annoying sound. Hence the reason I chose the straight face. That's pretty much my main concern. Either it's clogged or it's not seating the right way. I will add a lifter cleaner, then go ahead and drain the oil and see if that goes away. If not, I am taking it back to my mechanic to address the issue.

Interior headliner lights don't work.

I have a brake light that I might have to replace both sockets.

It has like an old metal scent to the interior.

The body has zero rust.

I do need to replace the lower control arm bushings, so I can get a good alignment.

General Comments:

Overall it runs fine. Just wish I had more money to restore it.

Great car up until now - hope we can save it


Head gasket blew at 160,000 miles.

Seat belt latches had to be replaced.

General Comments:

Great family car! Bought it new in '91 - our first SUV. It's been 4-wheeling in the mountains above Boise, ID.

It was the first car my first son ever rode in as a baby, and now it's his car. I had the engine rebuilt and fresh paint put on it for his 16th birthday 2 years ago. However, now, 2 years later it's having some problems. It has no power from a stopped position - seems like it just can't get any rpm's... in fact the rpm's go so low the engine nearly dies, but doesn't. I have it in a shop, but they can't figure it out. Not a plug, not wires, replaced all those plus cap and rotor. Replaced throttle positioning sensor and coil. Still does the same thing. Could it be the injector?? Any thoughts from anyone? Thanks!

Check the catalytic converter; it might be plugged.

Excellent on/off road vehicle


I've taken very good care of my Montero. Bought it new. Always used full synthetic oil.

At 268,000 miles I am now experiencing low idle and low oil pressure. I think I need a new oil pump, but not sure if I should bother on a motor that has this many miles on it. I've driven it hard, but have taken good care of it. Little things are going out, electric window, door handles, that kind of stuff.

What is the best advice to keep this car on the road, or is it a cash for clunkers now? Can I replace the oil pump without having to overhaul the entire motor? Are new motors available?

It's not a Cash for Clunkers. That deals over. I'd fix it. You've got a real gem.

A beautiful car with lovely accommodations


Replaced a fog lamp. It was cracked and had rusted.

Fixed tear in leather seat.

Antifreeze leak.

General Comments:

This is a beautiful luxury SUV with all the accommodations one could ask for.

I absolutely love all the extra features on my car (Voltmeter, oil pressure meter, limited slip differential, etc.).

There is plenty of cargo space, but I wish there were an extra row of seats too.

I love the huge windows. They allow you to really enjoy the scenery as you drive.

Sitting high off the road also gives you the confidence to tackle any obstacle.

If your looking for high class off road ability and luxury, the Montero LS is it.

A solid performer


Transmission leaked fluid excessively at 174000, required a rebuild.

Engine leaked oil excessively at 175000, had all seals and gaskets replaced.

Engine still uses a lot of oil.

Defrost setting of the ventilation system didn't work due to a disconnected cable.

Alternator failed at 182000.

Water pump failed at 191000.

General Comments:

Considering the age and high mileage of the truck, it holds up really well - in fact I am surprised that I didn't have more failures.

The engine could use more oomph at higher speeds and steep grades, but is more than adequate for everyday driving. Fuel economy was surprisingly good: 14..17 mpg city, 18..20 mpg highway.

The standard alternator is on the weak side: voltage drops noticeably when the engine idles.

Handling is good for a truck of this shape; however the seats lack lateral support in tight turns, and body lean can get scary at times.

Low-beam lighting range is too short for my taste.

Ride is bouncy and a bit too soft for my taste, but not excessively so, and the suspension and high ground clearance inspire confidence to tackle off-road terrain.

The stop-and-shift part time 4WD system is primitive, but effective.

Visibility is good, thanks to the huge windows. However, the side mirrors could be larger to reduce the blind spot.

I really appreciate the huge, boxy cargo space: with the backseat folded up, it is big enough to hold a fully assembled road bike, or lots of camping gear.

The design of the body shape doesn't appeal to everybody (and makes it sensitive to crosswind), but gives the truck a unique utilitarian look.

In summary I wouldn't call the '91 Montero an outstanding truck, but it is a solid performer with just the right blend of performance, utility and looks.

Bilstein Shocks did wonders for my `91 Montero because it does not lean in curves. Much better high wind stability. Gary Z.

Completely agree about the tiny side mirrors, they should be larger. Though I´ve seen quite a few Monteros with larger ones... Wonder why mine are so small :-/

My mirrors are huge!

My truck has 191,000 and is still running strong, I can't wait to put a twin turbo 3.0l mitsu engine it it.
