He has removed the listings for some reason. The repair parts listings have been on constantly for the last 6+ months.

First of all, I want to thank everyone on this site about the information about this TSB repair. I own a 1999 Windstar SEL and I had these codes, did the required TSB work, and the codes cleared (about 2-3) weeks ago. I have been suspicious about a noise I am hearing under the hood though. I do not recall hearing it before the repair but that does not mean much seeing as I was not really paying attention. I am hearing what sounds like a vacumm leak around or inside the plenum. I have sprayed its perimeter and hoses with throttle body cleaner while it is running with no change in idle. It is only apparent when i apply throttle quickly while the hood is opened. I put my ear to the top cover of the plenum and can hear it there stronger. Is this normal with the plastic plenum material? Would this sound be normal had the upper intake been made out of alluminum. Is what I am hearing just the air being sucked through the upper intake into the lower? I am just concerned that something else is wrong. I also observed something odd while giving the van throttle. It appears that the upper intake plenum swells slightly when throttled up, almost as if it is a breathing lung. It may be the fumes from the carb cleaner, but who knows. HA HA. The van runs great and there is no CEL. Does anyones else van sound like this to with the hood open and giving it throttle? Any insight or similar noises may hoppfully put my mind at ease. Thanks again.

I have a 2001 3.8L and my mechanic is telling me there is a leak on the lower intake manifold where the small rod goes through to the dual plane. He tells me that I'll have to replace the entire manifold ($325) because he knows of no repair for that seal.
Has anyone heard of a repair for this? Seems nonsense to have to replace the entire manifold because of a seal which can't cost more than 5 bucks!

I have always heard what I consider to be an unusually loud vacuum sound but I accepted it as most likely normal. (though I could be wrong).

Isn't the intake too rigid to flex? Is it collapsing? If so this would seem to suggest that the intakes to the cylinders are demanding more than the intake will allow. I can't see that occuring at relatively low RPMs unless you have some restriction in the intake. Even a clogged filter.

OK, I did the TSB about 2 years ago and got the new valve cover, and reflash. I get no codes but still seems to have some hesitation and oil pool up in the upper intake. I also just recently purchased a smoke machine and found that when hooked up, I get smoke from under the EGR housing (not the connection to engine point), from that button thing on top the IAC valve and more than I would like from around the IMRC bushings. Should I be getting smoke from these places as described?

Another seller has the repair kit listed for sale on eBay.

I'll Be dog!!! That is a Great price. If anybody need to do this job.. This is a steal.. Even comes with the valve cover. You may have an updated one already. But new is new and I paid that much for the isolator bolts and port seals alone> With a discount.. Thanks for posting this This could help someone save a lot of money even with the 12.75 shipping its a bargin.
