FYI-4.6 intake problems

[PKRWUD]

Greetings

I am a member of a website that is only open to ASE certified mechanics, and from it I receive close to 100 emails a day about problems and fixes that other mechanics are having. Anyway, when I see something of intrest, I like to share the info with others. Below is one I received today. I don't know if this has been covered in this forum or not, but it is something to watch out for.

Take care,
~Chris

Affected Item: Intake Manifold


_____________ ORIGINAL MESSAGE: _____________

We have tried to 'patch' a crack in this $250 composite
intake manifold with out success. Does anyone know of a
substance or material which will mend this defect, causing
coolant to leak out just behind the alternator? We have
drilled both ends of the crack, tapered the valley and
applied JB Weld. It doesnt last long. Factory assistance
refused or unavailable. Thanks.

________________ FIX: _________________

There is no 'magic sealant' for this situation. We replaced
the manifold and judging by the response, this problem is
occuring throughout North America. It seems that in some
places this is covered under some phantom warranty and in
others, it is not. The fact that this does not occur untill
70K+ probably has something to do with the warranty
coverage. Many thanks to all of you techs with the
sensible, constructive answers.
