I pulled together this information prompted by this thread:
http://www.fiero.nl/forum/Forum2/HTML/107934.html

Thanks to those who's pictures I've borrowed to illustrate things in this thread.

People are still finding a disconnected pipe or hose of the firewall below the rear window.
Sometimes it's a hose, or has a metal elbow, or just a tube on the firewall.



This originally ran from the valve cover to the air cleaner (to bottom of intake tube on some).

It seems half the recalls were done by guys too lazy to remove the hose and cap the ends of the tube (or plug hole in air cleaner housing), so they just left it hanging to suck dirty engine bay air into the air filter housing - bypassing the air filter.





This change was part of the recall kit.



A new metal tube was installed that ran from the valve cover to a NEW rubber intake tube. The tube on the firewall is no longer used.

The recall is also when they removed the decklid weatherstrip on the leading edge of the decklid.

The idea was that it would allow more hot air out of the engine bay, but removing it allowed water to fall through past the window onto the engine and exhaust manifold - and the thermal shock caused the exhaust manifold to crack in many cases.

I still don't understand why the recall was even done on the V6s...? Doesn't make a whole lot of sense.

Anyways, carry on.

The reasons the recall was done on the V6 alot apply to the 4cyl too.
The PCV hose was moved to prevent the air filter from being soaked in oil,
The big heat shield that goes between the manifold and the block is there in case the block decides to let a piston go through it and make a hole and dump coolant and oil on the CAT, catch fire.
The heatsheild over the manifold is to prevent heat on the wiring harness, which the loom can become brittle and break off, fall on the CAT and catch fire.
The decklid weatherstrip was removed because it can become brittle, break off, fall on the CAT, catch fire.

As you can see this is where GM was going with this.
The CAT is a huge plate to light things up too
I have seen some of the decklid strips do just that get real brittle and break off, the CAT is straight below.

Nice job Fierosound.

I appreciate you putting the pics and info together. When I bought my 85 it had all of them done on it so I never got a chance to see what was changed.
I have always wondered what was done for the recalls.

Maybe this could be added to the new How To section...

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 don't think my car ever got the recall done. I have added the CRX intake and here is how I have it. Let me know if there is anything wrong. I hooke up the 2 hoses on the firewall and the sensor too.

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.

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.
