There's a high probability of recently 'first-time' Fiero owners which are likely uninformed of the 2.8L V6 Recall and Searching the Entire PFF for 'Recall' gets hundreds of threads!

Seasoned PFF members might tell the tale; although some veterans rather not rehash it when newer members repeat the same questions.

Also, some details of the GM Campaign 88-C-24 are forgotten including new parts which aren't illustrated in the factory manuals or part catalogs.

Plus, the formally "General Motors Company" purged Fiero Recall History from their database before the 2009 Chapter 11 reorganization which "General Motors" is an entirely different new company.

So, this thread is a "sticky" for members who have a desire to refer to on this subject!

One question arises often these days:
"Please help me figure out what is missing from this metal pipe in the engine bay on the firewall."

quote By IMSA GT: That's part of the GM recall. It is abandoned during that recall and does nothing.

This 'metal pipe' was connected to the Engine Crankcase Vent as shown in the photo after the recall procedure.

On the other end of this pipe is an Either/Or:
1st Design was connected with an elbow in the bottom of the original rubber Air Intake Duct near to the Air Cleaner Housing.
2nd Design was connected with a prebend rubber hose to the side of the Air Cleaner Housing.

The recall 'Air Intake Duct Kits' removed the original air intake duct (between air cleaner housing/throttle body) and the crankcase vent tube from the pipe on the right.
Then installed a New Air Intake Duct which has a port for the New Engine Crankcase Vent Tube on the throttle body end.

Confirm the type of Air Cleaner Housing that the vehicle has; the recall illustrations in the link below shows both designs as well as the original parts were removed/discarded.

If a 1st Design vehicle has the new recall New Air Intake Duct/Vent Tube; the metal pipe was disconnected from the intake/vacuum system directly below the air intake duct.

If a 2nd Design vehicle has the new recall New Air Intake Duct/Vent Tube; CHECK this 'metal pipe' to verify:

*IF the Air Cleaner Housing Side Port has been Sealed (capped off)
OR
*IF the prebend rubber hose is connected between the metal pipe AND to the Air Cleaner Housing Port.

IF the Air Cleaner Housing Side Port is connected to the pipe; a rubber cap is needed to seal the end (not 'open' as the photo above) as this tube is still 'LIVE' and can draw unfiltered air to the intake/vacuum system which is a dire condition!


BTW: On my '88; the GM dealer installed a cap on the pipe and didn't remove the rubber hose nor a "Campaign Identification Label". I removed the hose, sealed the air housing port and my metal pipe is 'dead' on the firewall.

--------------------------------------------------------------------------------------------------------------------------------------

On the original parts which were removed and discarded is the infamous "Deck Lid Rubber Dust Seal" that many owners wished they still had the seal!

BTW, I queried 'The Fiero Store' to reproduce the deck seal and clips:

quote Matt at 'The Fireo Store': Your point is well taken, and we have thought about reproducing that seal a couple of times in the past. Unfortunately, we haven’t seen the demand spike enough to justify the tooling cost and a large production run. We certainly can’t rule it out for the future, but nothing is imminent at the moment.
