2.3 inlet manifold rubber gaskets

My inlet manifold that I fixed up with Quik Steel & JB Weld & replaced a year ago has started leaking again  ....can't complain though, the repair has lasted for about 25,000 miles 
Got a real nice spare one in the shed that I'm gonna sling in at the weekend (weather permitting), but was wondering whether I should order new rubber gaskets from FMD ? 
When I replaced the manifold a year ago I bought a whole set of new gaskets from FMD & seem to remember that they were quite pricey (about £40).
Will they have squished & flattened off that much to warrant needing a new set, or will they be re-usable ?
It would be nice to save a few quid

You have a 2:1 chance on this one,  if you fit new then you will know that it would be ok (or should be) If you fit the old ones a: you have the chance to inspect them before fitting and b:if they are ok then you save the money.... 
Personally I would take a chance on re-using, then IF there is a problem the worst thing that can happen is that you'll have it to strip out again to rectify. 
 But then again, I don't have to rely on my car for income.
Another way is to get the new ones and if not needed you could return them... probably have to pay a handling charge though.....
 Swings and roundabouts time I think...
best of luck with it....

ORRRR... you could fit the 2.0 metal intake + it's coresponding gasket like i did on my 2.3 The plastic intake was ok (no crack, no leek), but the 2.0 one is relay making the 2.3 lump go

Does it just nut & bolt on or does it need surgery to make it fit ?

You just need a new 2.0 intake manifold gasket, a plastic T connector and some pieces of hoses or L shaped connectors. Also the wiring must be a bit modified. I'm running a 2.3 with 2.0 sensors so the plugs are a bit different. It took me just one day for the full swap (including an oil + filter change as the car was lifted on jacks )
Beside the manifold you need the air ducts, resonator (air tunnel from the MAF to the throttle bodies)
Ohh and you must adjust a air bypass screw as the autobox version needs more air than the idle control valve can supply.

I rang FMD to get some gaskets, but guess what.....got to get them in specially & won't be till middle of next week
Decided to go with old gaskets as they looked okay....all fitted back in now & seems fine
One thing though....on inspecting the old manifold....it wasn't the old repair that had failed.....I had just assumed it was leaking through & down
It had actually split underneath, along the bolt shaft

Right then....all is not fine now  .....It all seemed well until I started to really drive it.
Every now & then, when you dip the accelerator, there is no power.....like there's no fuel....then wammo !!....it suddenly takes off again
I'm putting this down to the fact that I re-used the old gaskets & air is getting in somewhere....but where, I'm not sure, as all seems to be sealed. But will defo be ordering new gaskets tomorrow just to make sure.
Another problem that seems to have surfaced is that the rev counter seems to have become erratic....I'm putting this down to the fact that I gave the alternator a good (accidental) soaking of water when flushing the cooling system ....It may pass, or it may need a new alternator. But it's still charging at about 14.2 volts, so that can wait
Main problem is the temp guage, when normal (middle) keeps dipping when I press the accelerator .....
....Why ?....because the new (second hand ) manifold that I have just fitted has a hairline crack that isn't visible to the naked eye, but is big enough for anti freeze to seep through
So I'm off the road for a couple of days while I wait for FMD to get the gaskets. So off comes the manifold again & out comes the Quick Steel
If this happens again, then I'm going for the 2.0 manifold conversion

Jon, this lack of power, is it going lean when it happens?
If loads of air were getting in then I think you'd hear it pinking, or at least get a lean miss. Is the vac line from FPR ok? Fuel pressure dropping through lack of vacuum maybe?
You really need to get some OBD data mate, it's the best thing I ever bought for mine
TPS, fuel trims and MAF for a start, could tell you a lot...losing power isn't something you want pulling out onto a fast road with a fare onboard. I won't even go on a long journey now without stowing the laptop in the boot, just in case.

Thanks for the pointers guys, will check it all out.
The car was running perfectly until I started messing around with the manifold,. I've ordered the new gaskets, so it's just a matter of stripping it all down again, repairing the manifold , & making sure it all goes back in as it should.
I'm also wondering whether the spark plugs may cause this strange sudden dip in power ? They've done about 20K & look okay, but it's hard to tell what they are doing when they get hot. So I've got a new set of plugs as well.
I have tried swapping the coil packs & HT leads, but no difference & the loom is all still intact. Have also swapped FRPR, but also no difference

Sounds like a dip in manifold vac when you give it throttle, could well be some air getting in somewhere. I drove around in a car which was running lean for 6 months, I know the sort of symptoms it causes
A 4.0 with the power of a Fiesta is not fun
One of the guys on another forum pointed me to Iridium plugs, I bought a set when I was troubleshooting but never put them back in yet for some reason
Might not give noticeable improvments in the running but they're supposed to take less current so give the coilpacks and HT leads an easier life, might be worth thinking about.
Regards,Bruce.

Just got back from FMD with all the stuff apart from 3 fuel rail 'O' rings. They only ordered 1 instead of 4 ...... So they've had to order 3 more, which won't be in until tommorow......how frustrating
Bruce, I reckon you're right about a dip in manifold vac when giving it some throttle. The manifold is out again & it does look as though there is evidence of a slight leakage, it looks as though fuel may have leaked very slightly from one of the manifold gaskets & one of the fuel rail 'O' rings.
Hopefully, once all fitted back in with new gaskets, then fingers crossed, it'll be fine again
But because FMD f****d up the order, then that won't be until tommorow....so another night off work
At least the weather's nice.....so I'm gonna go & work on my tan & have a few beers

Jon, not sure how much your code reader can do, but if you ever want a full scan just let me know, I've got the full laptop setup and some good software so I can pull live data and things with it.
Best thing is to do a scan and record it while the car is running good, then you've got the info to compare to when something does go wrong...MAF and TPS values, ignition advance etc. Nothing worse than having all the data but having nothing to compare it to
Anyway, the offer's there mate
Regards, Bruce.

Bruce....my code reader can only read stored codes & that's about it.....cheapo Autel from USA
If it doesn't go right after this, then I'll let you know.....thanks for the offer mate
