4.6L engine question

I was on the Crown Vic website, and there was some discussion about
cracking and subsequent coolant loss from the plastic crossover pipe.
The permanent fix is replacement wit a manifold that has an aluminum
crossover.
Some questions:
1. How frequent is this problem? Consumer reports indicates a very low
percentage of failures in the engine/fuel/coolng system categories.

2. If it is frequent, is it a high mileage/hard usage kind of thing?
The guys on the Crown Vic site seem to be performance oriented, and
likely push their cars harder than the average driver.

3. If a crack does occur, can a temporary repair be made with epoxy/KB
Weld, etc? By temporary, I mean lasting long enough to get back home
from a trip, say 300 to 500 miles.

4. Does anyone know the cost of replacement and intallation of a
manifold with the aluminum crossover?

Thank you guys for the feedback on my first post, and thanks in
advance for this one.

George

It's not going to happen all the time, but a lot of require it. You can
take it to the Ford dealer to have it fixed and the new, improved,
reinforced with metal intake costs about $500, plus the cost of
installation. The aftermarket has jumped in and has the same design
(with the reinforced crossover) costing about $200, plus the cost of
installation. Of course, the Ford dealer will not install the
aftermarket intake manifold, but any good shop can.
I've never seen one that could be temporarily fixed with JB Weld.
The later model engines have this fix from the factory.
If you need a source for this intake manifold, let me know. Otherwise,
it is available at your aftermarket auto part stores, just maybe not at
the national chain stores.

It actually is fairly frequent. Mine did it around 90,000 miles I believe. I
went to Ford & paid $140 for the revised intake manifold w/ the metal
thermostat housing, etc. Paid not much more than that for labor.

Intake manifold was replaced by local mechanic and Ford paid the bill.
"Recall" item or something like that. Look it up.

Yes, it was an actual recall on 96-97 I believe... but just a TSB for 98.

Typically, when these things go, is it a catastrophic failure that
dumps out all your coolant and leaves you stranded, or is it more
like a slow leak?

Thanks,
George

P.S. I have a line on a 97 Grand Marquis, one owner, clean title,
54,000 miles at a good price, but it has the original
manifold....that's why I'm pestering you guys with these specific
questions. Thanks for your help and patience.

Usually, it is a slow leak. If I were you, I'd stop by your friendly
(when YOU are paying the bill) Ford dealer and ask if your make and
model is under the recall. They will run your VIN and at the worst tell
you that it is not.
The catastrophic failures are the GM 3800 V6 models that have the
plastic engine manifold by-pass nipples. They get old, break and in 15
seconds you have lost all your coolant......
To prove my point, the GM replacements are steel.
memset@recorddeal.com - 08 Apr 2005 22:02 GMT
Mine was a rather slow leak that was detected early. I used high-temp gasket
maker (the orange goopy stuff) as a temporary fix to get to the Ford
dealership to get the intake manifold & then to the shop to get it
installed.
