When I took the intake hose off to clean up my TB, the pipe that leads to the back of the valve cover feels a bit wobbly. Did I knock something loose or is this normal?

I still don't understand the water part, allow me to explain:
When the car is moving, water shouldn't get to this point - maybe when standing still and in a heavy rain. When you open the decklid the rubber pulls away from the window and water still runs down onto the manifold.
As for the manifold cracking, IMHO, I personally feel that this is due to the short exhaust system and it being spring mounted. There some weight here and it does bounce when the car is in motion and this movement is then transfer up to the manifolds and attacks the weak point. I 'think' that installing one of those flex tubes between the y-pipe and where the cat noramlly is would help solve this issue if this is indeed the case. All cars today have this flexable tube installed.

The dealer's ?mechanics? butchered the recall job on my 85 GT when they installed the sheetmetal shield. Years later I discovered a pathetic attempt to weld some of the exhaust manifold IN PLACE. wtf? How did they even get a weld tip into position. Idiots!!

True. The weatherstrip may have another purpose.
Those of us who have reinstalled the weatherstrip have found the rear window glass does not get as HOT.
When I didn't have one, at times I found it was like sitting in front of an open oven door!!
Without the weatherstrip, engine heat off the exhaust manifold comes straight up the firewall onto the rear window.
With the weatherstrip, hot air has to escape through the vents at the sides of the engine bay as intended.
Even the vent panels also have a rubber strip on their front edge against the rear glass.[This message has been edited by fierosound (edited 02-07-2015).]

When I went looking for a new manifold several years ago I called GM's consumer department to complain about the recall and discuss my options.
They said they would offer me a new manifold for half off.
Well the front manifold listed for $250, and it would be $125.
So I asked what the rear one listed for, $125.
He got an ear full from me on the bait and switch.
So I asked if the recall kit was available and how much.
It listed for about $100, and he offered 50% off to appease me.
I picked a dealer who was close and had it in stock, he set it up and I walked away a happy guy, well until about halfway through replacing it, what a pain!

I noticed my 88 had the recall done when I did a rebuild on it, they left the extra exhaust manifold gasket off, 2 of the exhaust manifold bolts were missing and the manifold had cracked almost all the way around. Someone at some dealer ship was very lazy, of course after doing a dozen of those recalls I would have been ready to shoot myself.

I plan to reinstall a rubber gasket here because of the water that comes in when I open the decklid to get at the trunk. The cooler rear window will also, hopefully, be a nice change!
On the other hand, I really believe this car would benefit from a flexible section like you mention. :)

I'm not really following this. I have had my '88 GT V6 for 8 days so I'm not conversant on all the terms and issues. One thing that caught my attention right away was rain water falling directly onto the engine when the read deck is opened. I thought it was odd but this thread is making me wonder if this should be happening. Is there supposed to be a feature to prevent this or was that feature removed as part of a recall?
-------------------------
Found my answer in some recall docs, The rubber seal war removed and I can see the mounting holes that remain in the deck lid. Still seems strange to see all that water draining onto a hot engine.[This message has been edited by Rsvl-Rider (edited 03-31-2014).]
