You did a REALLY great job with this video tutorial. Thanks for putting so much time into the editing and showing how the connectors work for the layperson mechanic. Appreciate these great instructions and about to do this project this weekend!
2008, 3.8L job happening. Diy, kind. Thinking i could work without paper towels, some things happend with my planned job. And im wondering if i need to delve even deeper into learning this fix. And fixing any potential mistakes the first time. Reinforcements on the way! The woman with paper towels and cleaner. Thanks!
How do I know if it's my uper or lower gasket that's leaking? I'm getting lean mixture and I can hear the vacuum leak coming from the intake but now idk
@@ianworkman8199 It's hard to tell without a smoke machine. This one was replaced because it was leaking coolant out of the lower gasket. It's pretty common for these engines.
I ended up with an idle issue afterwards. Possible I messed up the IAT sensor everything is new and clean. Or possible iac coincidently failed all plugs and wired new too did all the maintenance suggested in video. But never had an idle issue before doing this repair. Any ideas?
@ValleyMobileAutomotive idles like it's chugging when u out ur hand on the plenum you feel it gurgling. No power at the pedal when trying to accelerate. If depressing accelerator in park it revs up fast but has a hard time coming back to normal.
The bracket under it covers half of one of the bolts holding the lower intake down. Because of the angles you could use a crows foot wrench to slowly get that bolt loose, but I wouldn't because when you go to put it back on there's some really finicky torque stuff to do. Much simpler to pull it off. A tip, before you pull of the spark plug wires from the coil pack, put zip ties on them all and cut them at ascending lengths. Then take a photo or video to remember the order. Makes it real simple to see which one is which.
I believe it was Fel-pro from the local parts store. I think there are better gaskets out there. I would look for one that has a rubber bead around it to seal better. The Fel-pro is just a metal gasket
My Fel-pro gasket had black rubber gaskets already on the bottom ends of the valley gasket. I also put a little Ultra-black silicone sealer in the bottom corners, and around the water pass-throughs. The additional set of gaskets, each kind of oval with a flat side, are the replace the old ones in the upper plenum.
Good Evening my friend and nice to meet you! My factory service manual book says to install lower intake manifold. Install the bolts and torque to 1 N.m (10 in. lbs.). Then torque bolts to 22 N.m (200 in. lbs.) in sequence. Then torque again to 22 N.m (200 in. lbs.). After Intake manifold is in place, Inspect to make sure seals are in place. In your video you say to tighten lower intake manifold bolts to 10 inch pounds in the sequence Then again 100 inch pounds and then finally 200 inch pounds. You lost me when you said 100 inch pounds for the second torque. The factory service manual doesn't mention 100 inch pounds for the installation of the lower intake manifold. Where did you get 100 inch pounds from? Just asking with all the respect no disrespect or offense at all. Im very appreciative of the time and detail you put into this video great work my friend keep it up!
Hey good question. It seems like our service information varies slightly. The important thing to note is that you tighten the manifold in increments not all at once and the final torque is 200 inch pounds. The results will be the same either way 👍
@@AlwaysDiagnoseVehicleFirst Doing it in increments ensures a good seal where the manifold has a chance to settle against the gasket in the best form. It's analogous to putting the lug nuts on your tire in a star pattern -- you don't tighten the nuts to their full torque (100 foot pounds) immediately -- you finger-tighten in a star pattern, then tighten them up a bit (in same pattern), and then reach 100 ft/lbs. The reason for the tightening pattern is to ensure that a person doesn't start on the left end, tighten it completely to the end spec, and then get to the right end and have it raised due to high compression of the gasket on just one end. Another analogy would be placing yourself into a foam mattress. If you put all your weight on one end, it'll sink, but if you can gently place your entire body down on the mattress, your weight will be evenly distributed without causing a sudden indentation in the foam. For the car, that foam is the gasket!
@@jasonbengel I dont understand what your explaining cause im not good with vocabulary but i really do appreciate your reply in detail explanation it means alot to me that was very nice of you 💚🫂🙏.
@@AlwaysDiagnoseVehicleFirst Here's a better explanation. Make two peanut butter jelly sandwiches, and put a LOT of jelly in both of them. For one sandwich, take a rolling pin and squish the sandwich by rolling the pin from one side to the other. For the other sandwich, take a book and press it firmly on the sandwich. Take a look at how one sandwich has goo coming out of one side of it (the one squashed by the rolling pin). The other sandwich has goo equally distributed on all sides coming out. We want equal pressure when tightening down components on gaskets, so that the gasket isn't squeezed hard in any one direction.

Very nice and helpful video .Thank you . I'm going to do this job next Saturday.
Thanks man, your video helped me a lot.
Awesome! Glad this was helpful 👊
Nice video took my 3.3 in oil leak lower intake, I have a good macanic just wanted to see what he was doing, hes done a few of these, time consuming.
Great vid. Thanks
You're welcome 🙂

We did this job on our '05 CTaC 3.3 but now it idles high, any idea why?
Vacuum leak In most cases vacuum leaks raise idle speeds
I ended up with an idle issue afterwards. Possible I messed up the IAT sensor everything is new and clean. Or possible iac coincidently failed all plugs and wired new too did all the maintenance suggested in video. But never had an idle issue before doing this repair. Any ideas?
What is the idle doing? Because this is a speed density motor a fast idle may indicate a vaccine leak.

Egr isn't on properly
The gasket on the egr tube could be bad or broken
The Intake Manifold gasket is made of thin steel, it also comes with some rubber gaskets. I see on videos that these are never used. Why is that?
Wait why did you need to remove the coil pack ? Seems like it wasn't in the way
The bracket under it covers half of one of the bolts holding the lower intake down. Because of the angles you could use a crows foot wrench to slowly get that bolt loose, but I wouldn't because when you go to put it back on there's some really finicky torque stuff to do.

What brand gaskets did you use?
I believe it was Fel-pro from the local parts store. I think there are better gaskets out there. I would look for one that has a rubber bead around it to seal better. The Fel-pro is just a metal gasket
@@ValleyMobileAutomotive Great video by the way. You sound like you know what you're doing.

Is silicone Required for this job?
