Rebuilding a Gen 1 Montero Engine

In this video I transfer all the parts from the old motor onto the new block. This includes a new timing belt/water pump. I ran into a few challenges along the way, but it's finally ready to drop in!

Nice work! It takes some guts to drill a block. Don't forget to off up that core block- it is probably just fine, even with 300K miles. They are strong blocks. GL with the rest of the work and thanks for sharing.

I appreciate videos like this immensely. Not likely that it'll get a million views but invaluable for a niche group of people. My 1990 needs this exact treatment almost. Where did you/owner buy the engine? I'm curious about availability and cost.

[@WilliamLaakkonen]

The factory never used a oil pan gasket. If you use Hondabond HT- you will likely never have a leaking oil pan. The oil pan gaskets will always leak. Glad to see you figured the non interference part.

Great video man. I did a motor swap on my 93 a few years ago. I got the block from engine world for 500 bucks. Short block with super low miles. Swapped all my stuff over in about a weekend or so. Just had to wait for some odds and ends coolant parts like the housing and hoses.

That's the blessing about the 12valve 6g72s....they are non interference motors. I am curious, where did your friend get the new shortblock? I MAY need one for the Gen 1 we saved.

I totally needed this video 😭😭🎉🎉

[@WilliamLaakkonen]

SOHC is a non-interference engine. Most likely you will find no valve collision damage. The bolt may have been over torqued. The whole engine is severely neglected.

[@JohnnyBfromPeoria]

The old style crank bolts tend to break. Any of them will back out if they're not torqued correctly, but that's not why they're onto a third iteration. In my 95, years ago, mine broke off flush with the crankshaft snout and it was NOT fun to fix.

This was very helpful! I have a 1990 Montero RS that I am working on and this is my first time digging into an engine like this. How exactly does the dipstick attach? I am trying to remove the exhaust manifold and I cant get it out without removing the dipstick. Does it just pull out? My engine is still in the car so its not super easy to access. Any tips?

[@mitsuevo8mr]

Those 3.0L umin the first gen Montero are non interference! Valves and piston should be alright!

[@davidkeetz]

Those bolts like to break - I’m only a couple of minutes in, but if this is really a gen 1 montero engine, it’s non-interference so shouldn’t be any bent valves or damage on the cylinder tops

[@montanamontero]

Yep I figured that out in the end

[@gearhed79]

What's it cost to rebuilt one? I have a 1990 w/ a blown head gasket and was thinking of just rebuilding the whole motor... 192k on it. Thoughts?

[@user-uk3uj6zs1w]

What did you do? I have a 1999 with a blown head gasket also. 254K on it!

[@golfsidedr]

Where did you get the new motor?

[@jwelds9974]

Hey bro, can you drop a link for the timing tool you used to grab the cam wheels

[@kyletucker6508]

Hey! wanted to know your thoughts on the Montero sport version. Looking to by a XLS 97' and im wondering about it compared to the Gen 2 montero

[@montanamontero]

I don’t know much about them actually. The one I had was a 2000, and i liked it all the way up until it blew up on me haha

[@robertnicholson1525]

Hi from South Africa I've got a Gen 3 Pajero v6 3.5 GDI. Where did the exhaust manifold crack. Just interested as I'm getting fumes into interior. Carnt find hear any leak. Thanks

[@montanamontero]

They crack in a few different spots, usually you can’t see them until you remove the dust shield

[@robertnicholson1525]

@@montanamontero Thanks for the feedback

[@andrescortez4945]

Where did he source the new engine? I wanna do the same thing

[@montanamontero]

at this point i can't remember... some shop in california

[@jaygatsby2790]

You didn't clean shit. You just bolted on the gunky parts on a nice new engine.
