so i was driving my girlfriends 4.6 t bird and i got on it think nothing of it. well she looks in the mirror and its smoking like none other. thank god we're 2 sec away from my house and i pop the hood HOPING for the radiator to have bisted. no such luck. thePLASTIC intake manifold cracked. fucking ford...
and on top of that fiasco i went to the JY to find a mani and i guess thats a relatively rare motor... and i found a bad ass 3g hatch lxi with a 5 speed but some ass hole broke the hood latch so i could steal any goodies!!!!
that sucks
imports FTW

they actually make manifolds out of plastic? lol
pull off the front bumper then you can unbolt the hood latch boltsOriginally Posted by oscwrestler
yup gm is a fan of plastic intake manifolds
thanks mkymonkey
bio degrading cars ,degrade when you drive them off the lot. fords logic: hey no one else makes plastic manifolds,lets try that!! other manufacturers logic: plastic manifolds don't last,lets sell the idea to ford for 100 million dollars.
The composite manifolds are fine if they're designed properly. LS1s don't have an issue with them.
Composite manifolds are lighter, don't conduct heat worth a damn so that you don't have to deal with heatsoaking, and most importantly for the manufacturer, cheaper than aluminum.
Also, what year is that car? I'd be willing to bet a manifold from just about any 4.6 can be made to work just fine.
A T bird with a 4.6 has to be pretty old, hey wrestler check your Ford dealer they were replacing those for free, it was a non expiring recall. They will look up the VIN and if it has not already been done they will do it free one time. Otherwise most of the upgraded versions do not have that issue, but do crack from improper torque on the thermostat housing.
Everybody is using composite intake manifolds now days. Nothing wrong with them IMO.
GM V6 intakes are the worst, they warp, crack, and take out engines at random.. but GM never attempted to make it good for out of warrenty vehicles. Also GM used silicone RTV as the entire gasket for them.

yes they have been doing that for a little while now , as far as i know the fords and some of the gm's are like that (Pontiac, buick , ect)
i wouldn't bee surprised that Saturn (if i remember right also a division of GM) has plastic engine components , i mean those cars ARE plastic themselves?!

Personally, I'm surprised that companies still make manifolds from aluminum. The price difference is huge, and the weight penalty can be significant.
Add BMW, Mercedes, to that list
Yea some fords are ok but most are like wtf
and which yard would that be? I might just have to take a field trip and treat myself to an early fathers day on Sat if it's worth while.
Let me know.

wrong state !
haha. shit. I swear he was in CT at one point. ...oh well, got my hopes up only for Guy to crush them like a bug.
Anyway, about these manifolds....
...are any aftermarket intake manifolds, that are made for applications using composite from the factory, made in composite as well? (Basically asking if any aftermarket companies have jumped on the composite bandwagon too.)

honda and many manufacturers have gone to plastic intake manifolds. The difference between honda and everybody else is that youd never ever have a failure like that in the honda

Yes, searching to back up my statement about the German cars I found a lot of aftermarket composites.
Fords are not that bad, they had several batches of bad intake manifolds in the early ninties. Aftermarket has stepped up like Dorman products that are problem solvers kind of like MOOG is with suspension. They have really nice intake kits for GM and Fords that elimnate sealing /cracking issues as well as making parts for many other areas of USDM vehicles.
Thing is all these USDM car makers pay other companies to make the parts to their specs and then they get screwed when that goes unchecked. GM is the worst with problems on 2002 -08 models having Chinese (and others) substandard parts.
well the car is a 96. i found a 95 with the same motor but in true ford fashon the like to be on the cutting edge every year and change shit up. i swear they get off on using untested ideas.
I would think you could use the intake off a Crown vic 96-97 as long as you get all of it up to the throttle body. The thing I would look for is hood clearance. Make sure you get one that has the alumninum around the thermostat housing. Have you even tried going to a good parts place, not the dealer, to get one new? Did you contact a Ford Service dealer to see if that car got the free upgraded intake yet?
well its not my car so after the jy i'm not handling any of it yet.
the only problem now,is when that ford catches fire from eithier A. bad cruise control switch, b. bad ignition switch, or C. other undetermined electrical problem, now you will have to replace the intake manifold with all the other plastic parts that melted
all i can say is only ford... who else makes cars that are essentially designed as fucking bombs?
phooey last two posts, exploding chevy trucks ring a bell , the biggest class action settlement ever in automotive history?
You are right to not even mess with it though, you will be in way over your head. I would never buy a used intake for a 4.6, it just is not how you do it, like buying a used water pump, used windshield wipers, used sunglasses..etc.
haha..its like buying used underwear
