Hello all, looking for a little repair direction on a 1990 Montero I picked up a couple of falls back. I've been a long time lurker on this site, always interested in overland vehicles. I've owned an Xterra, Grand Cherokee, Wranglers, etc for daily drivers. But now I have an awd car that I use as a daily driver and I'm looking into making an overland vehicle for vacations that would involve a lot of highway miles with some light offroad use for camping etc.

Which is where the Montero comes in, this is how I ended up choosing a Montero. Skip to the next paragraph is you're not interested in knowing, lol, but if you stumbled upon this post leaning towards picking up an older Montero you might be interested. I run a small carlot with my father so I go to a lot of dealer auctions. I started piling up overland candidates this time last year and at one point last November I had a First Gen Xterra, 3rd Gen 4Runner, this Montero, a 5 Speed Cherokee. (along with my Wrangler and Samurai which I still own) I also checked out a few 90's model Land Rovers I found at the auctions and finally decided on the Montero. I REALLY like that it was bar far the most rare to see on the roads, at least around here. The interior seems way more spacious than the X or the 4Runner. Drove it in some big snows last winter was amazed at how well it did.

WHICH BRINGS ME TO MY QUESTIONS: This Montero has the 3.0 V6 (with a 5 speed Manual, which was another big factor on my decision), but the head gasket is SHOT. I'm talking giant clouds of steam. I want to do the repairs myself but I've never seen a good review of a DIY headgasket walk through on this engine. I'm not afraid to tackle the job and I have the time to do it WHILE I'm at work. I also visit u-pull junkyards often, but from what I understand you need modifications to make the 3.0 from a dynasty or caravan work? I can get junkyard parts or order parts online and do all the labor myself but I want to make sure I have a good DIY handy or more information before i tear into the thing.
My main goal is to keep the repairs CHEAP. I've only got $700 total in the thing right now, the interior is in great shape, the 5 speed feels great, and the 4wd works flawlessly. Motor sounds good, just lots of steam out the pipe lol.
My longterm plans are I'd like to restore this thing's head gasket and body to it's former glory and pull either my Suzuki Samurai or Wrangler Sahara out west to play around and camp. I'd also like to be able to sleep IN or ON top of the Montero itself, but I'll make those plans when I get her road worthy again.

Thanks for any help pointing out posts I might have missed or any advice you have for me! I'm sure the number one thing would be to buy a manual on the vehicle, but what I've often found is a good diy in these forums is a thousand times better than a manual from auto zone, but i can go that route if I've got to.
Thanks again!

Pretty straightforward, I would highly suggest having both heads checked for cracks or warpage. Almost every single headgasket I've done on the 3.0's have had at least 1 cracked head. As far as using other heads, I would avoid it unless you are able to quickly identify what components need to be swapped over, otherwise you are going to most likely be installing and removing things more than once. I would also strongly suggest doing your valve stem seals and timing belt/water pump since you are in there.

Good luck

My 91 Montero is currently at my employee's house having the heads replaced. I opted to go with refurbished heads from National Cylinder Heads, which come completely assembled, pressure tested and mating surfaces machined, but still within manufacturer's spec. They only ran me $195 per side, I would be surprised if you could pull your own, have them machined and tested, and rebuild them completely for that price. Now I'm glad I went that way, because one of my heads was had a crack in it. It's nice to be able to just pull the old ones off and slap the completed ones on. Add to that, a new Timing Belt and Tensioner Pulley, Water Pump and all the gaskets and I'm only into the the project for under $600. I am paying my employee another $500 for the labor, so for $1100 total I have a completely rebuilt Top End and peace of mind for awhile to come. I was going to do it myself, but I just don't have the time right now.
