Greetings, fellow 3800 owner! Those plastic intakes are a nightmare. You can try swapping an aluminum one from a Series III motor on there, but it will require a throttle body adapter for the TB to fit. I think you are better off just getting a good aftermarket replacement like this one. They are pretty easy to install and it should last a long time. That ATP intake seems to be more durable and better made than the Dorman one, I replaced my intake with a Dorman one 2 years ago but I can see it warping near the TB slightly already. What car is that 3800 in? What led up to you having to replace the ICM?
Good thing it's only like 20 bolts to get to it. The plastic manifold likes to warp too, and a dorman replacement with all the gaskets is only $80 on Amazon. http://smile.amazon.com/Dorman-615-180-Intake-Manifold/dp/B000C17G5E

I went with this one when mine failed, can't be happier.
It's your intake tube/intake pipe.
They crack over time, so yeah, he totally tried to seal it with silicon.
They're cheap.
Here's one on Amazon that looks like it will work
This one is cheaper - might work too.
It's pretty easy to put on. Those two bolts, one clamp, make sure the o-ring is in place. It might be hard to cram your carb spigot into the new one the first time.
Your new one will wear out in a few years too...
I just replaced my 06 CVPI. I replaced with factory (https://www.amazon.com/gp/aw/d/B000CNHT0E?psc=1&ref=ppx_pop_mob_b_asin_title) and like it better than the dorman. Dorman/aftermarket fitting is weird (it works, but some bolts are 'tight' threading in) and the flash/roughness leftover from the plastic casting is rather nasty. It's a part you'll only replace once, I'd stick with oem. Ive done 30+ of these (I'm a mechanic.)
No access to ebay at work. Here's one on Amazon that has mixed reviews. Apparently some people do not receive all of the parts. I'd also still need the elbows and lower set, plus whatever else I'm not aware of.
I'm checking rockauto right now.
It's plastic on most new cars. It's also not available on the Cruze unless you buy it complete, meaning with the throttle body and all 4 injectors. You can still get one for ~$400, but that's a lot of money to drop on a cruze.
As for why they go bad, this is the fun part. Both the Intake and the Valve Cover have non replaceable one way check valves inside them as parts of the Crankcase Ventilation system, and both like to go bad.
Fairly common issue on lots of turbo cars, the VW/Audi 2.0 FSI motors have a similar problem with the valves going bad, but at least they are easy and cheap to replace.
Thanks.
After a few beers...
I pulled the trigger on it as well as a new intake manifold, a gasket, a Keihin carb, (I just bought a carb but could always use a better quality one). A gang of tools. This kit arrived as well as 3 different hi flow air filters due to some order confusion.
I hope all this, when installed and tuned, at least gets me to 38/40mph faster with good throttle response and is reliable. I'm not looking for top end speed so much.
This was just supposed to be something to learn how to 'wrench' on, but lately I've been wanting to fix it up all sporty like and actually use it as transportation.

Aluminum one for less than fifty bucks right here
Make sure that your carbs are synced and cleaned properly first. I bought mine from Amazon. Here is the the link. iFJF Carburetor Intake Manifold...

the shorter serpentine belt was needed after i removed the smog pump and not shown is the dart iron eagle heads i got on craigslist for a good deal, not everything in the build is there and some links might be bad though
as far as HP/Torque its in the 270-330HP range judging from racing against other cars in that power range
I replaced all the gaskets. The part I used was this. The kit includes new gaskets. I even used RTV silicon around all the o-rings that connect to the coolant holes in the engine block.
Thanks for the reply though!
i've never worked on a car before; i'm going to look for some quotes throughout the county over this weekend, and if i can't find anything under $1000 i'll pick this up and install it.
Here it is. This is the most widely recommended manifold because it is an OEM equivalent and is from what I know, the only one that will not lose you horsepower. I certainly feel a difference coming from the Dorman.
Note I did this on a 2007, so make sure the fitment is correct for your vehicle first.

Let me know if you have any questions at all. I also have photos from my breakdown. Several lessons learned on my end. Some big ones were:
Great site... i need the connector for this https://www.amazon.com/dp/B0080DJE92/ref=cm_sw_r_cp_awdb_HUUzzbQVC2CRV
I see the site you recommended has lots of connector pieces but without pictures it makes it difficult to know if I chose the right piece of they even carry it 😅
