Gen 3 Mitsubishi Montero 3.8l lower intake repair 6g75 2003-2006 

Another thank you for this, Long term fuel trims dropped from 12.5 to zero. Of course I did spark plugs ans wires while I was in there and kinda wish I'd done valve cover gaskets, but car runs bbetter than it has in a long time.

Cheers for the video, been having a leak for a while, swapped every vac hose lo and behold it was this. Will be swapping the o ring this week. Attempting the rocker cover seals this week for a roadworthiness check.

Great video help tremendously thank you

Awesome thank you

You have video on how to remove the intake? Good idea here. As you know the engine are getting harder to find parts. I'm stocking parts and doing small maintenance myself. Good work. Thanks

What are the torque specs after replacing the intake

Okay I tried this O-ring then put everything together ran the Montero came back sprayed the aria again the engine started stalling so for some reason the O-ring isn't working on my Montero what do you think i did wrong?

This assembly can be removed and blocked if you removed the secondary butterflies that are inside those ports. Those detective butterflies come loose and destroy motors. One reason why we see do few of these good vehicles. They did this to me on one 2003 and another I bought I removed them the first chance I got...sure enough there were loose screws and it likely would have destroyed the motor also. The butterflies aren't needed at all. No drivability issues or lights from them being removed on both of mine for years. If you have to wait to remove and reinstall the intake, because it will take you half a day to do the first time, you can cut that plunger shaft connecting to the intake, and then get good high temp sealant and slather it around the area with your pinky. Let it dry 24 hours and drive on until you get to removing the intake. Personally I don't take that thing off except when I have to.

Owen thank you for the video! Unfortunately, I ruined the orange plastic piece trying to get back inside the manifold. Been looking for a place to order a replacement but having difficulty. Any tips? Thx!

Does anyone hear run a transmission cooler in series or bypassing the radiator?

Hi, I’m currently doing the same repair at the moment and would also like to replace the intake manifold gasket for hood measures but, I keep receiving the incorrect type. I was wondering if there’s a special part number via fel-pro. It’s for a 03 montero limited 3.8L

Awesome video just completed mines today would you know the torque specs. Thanks

Is there a part number for the plastic piece or plug where the o ring goes into ?

Hey Owen, while trying to remove my plastic piece it snapped. it was incredible brittle and I tried to be as gentle as I could. the O-ring disintegrated as well. I put it all back together as best as I could but it does not start now. the leak is terrible. I was thinking of applying some kind of sealant around the area,.. what do you think?

Do you know what throttle body's will work on the 3.8 03 montero? Think the actuator is bad on mine

Just took my 2003 in for a diagnostic for p0171. They told me it’s probably an intake manifold tuning valve. Does that seem reasonable or would you think that this o-ring might be the root of the issue?

What number of pieces (punches) did you use to remove the pin?

are you still around and how much do you know about monteros i have a gen 3 2002 3.5l v6 and i have error p0300 i think its the spark plugs because they have never been changed and i cant find any videos with good quality or any documents that show how to do so. I refuse to take this car to a shop

Does this engine swap easily into a Montero sport? I haven't seen nobody done it before I think

Does anyone know the specs for the screws on the flappers? I checked the dealership with no luck I would have to but the whole part

I've taken my Mitsubishi apart three times trying this O-ring and then sprayed carburetor cleaner and it's still bogging out has anyone succeeded if so maybe I'm doing something wrong I've lubricated the O-ring put it back together still leaking??????
