Long story short as I have talked to 1 other person that didn't know about this 'deal'.

In 1996 Ford / Dupont decided a nylon/resin/whatever intake manifold (the part your throttle body sits on, not the part the air filter attaches) would be good.

The problem is the coolant crossover and heater line 'ports' end up leaking.

There was an actual recall in 1996, then they 'revised' the part but it was still faulty so they offered 7 year silent recall which is now expired.

Ford wants about $1000 to do the job. 4 hours labor and $750 for the parts.

Searching ebay and sean hyland Ford's website you can see an aftermarket deal that uses aluminum. Some have also used the later model manifolds with special gaskets and extra RTV and changing a few other parts. The special aftermarket one is nice as one it's only $200 and second it has all O-rings built in, just like the factory gaskets.

I realize there are a lot of take off manifolds out there, but when you are dealing with one that has a potential problem that develops with age I personally don't think it's worth it...if I were going for a GT-40 intake or other full aluminum deal then I would hunt used.

It's a 4 hour job (took me 6 hours+ the first time without manuals, just some printouts....but on a 98 Mustang GT you don't have to remove the EGR to exhaust manifold nut which I could not get to and wasted about 2 hours trying to figure out ways).

Labeling everything would definitely help the first time, second time I could do this in about 1/2 the time.

I told the lady $100 as I try to keep my shadetree stuff 1/2 mechanics, but she gave me $200 and covered the coolant and beer.

Saved her about $550....that's quite a bit for even a business woman. If you are in college or just starting off in the world of V8's the 'Factory' job may put your car on blocks. You will have to find a shop willing to let you bring your own parts, but IMHO this aftermarket deal was easier than the factory piece to do.

FYI: this job is grueling on your hands. Lots of sharp metal where you need to be. If you have sensitive ones better practice using mechanics gloves.

Thanks for the information. Looking to buy something possibly with that series engine, keep this in mind.

Mechanix gloves have saved my hands a many a times changing transmissions, engines, or R & R'ing front ends off of wrecked cars and trucks. Every DIY mechanic should have a pair. I've seen those intakes broke into pieces on a few wrecked Fords. I don't think Ford was keeping reliability and longevity in mind when they decided to make their intake manifolds out of fiberglass.

I've got a '95 G. Marquis and '94 Town Car that may use this intake. Gotta save every fraction of an ounce for fuel efficiency, eh? :roll:

I think I heard that this was caused by the water hose's outlet cracking or something like that. I was hoping it could be fixed with epoxy, if mine failed. :p

This intake cracked on my dad's '97 Crown Vic. He had it replaced a while back...wasn't cheap, either. :(

It broke right in the very front....the part has what looks like a series of small "pipes" fused together, crossing over the top. The very front one of those cracked, on the underside.

Was water seaping out of it, or air sucking in? If it's just air sucking in, I'd think you could seal it with something. Yeah, I'm a cheap SOB!

It actually happened to break while I was driving it. Of course my parents automatically assume it's my fault, since I've driven that car maybe twice in my lifetime.

It shot coolant EVERYWHERE. I noticed steam coming from under the hood (coolant steaming on the exhaust) and pulled over immediately. It was literally spraying out from the crack and going all over the engine. The crack was about 1.5 - 2" long, IIRC.

Water leaks out, more than likely air could be sucking in too...from what I have read it's not repairable.

I think it was a 96 and later only problem.
