In the General Fiero because these engines are popular Fiero upgrades. I suspect these are for 3800 equipped vehicles.
GM is recalling cars from 97 and later years due to the danger of oil leaks causing fires. The news brief didn't indicate which engine, but it was for Grand Prix, Monte Carlos, Buick Regals, Chevrolet Impalas and Luminas.
When my wife had her 2000 Grand Prix, we got notice of a recall for the same reason. Valve cover leaks would allow oil to run down on the exhaust manifold, possible causing a fire. Their solution was to remove the plastic raceway that held the spark plug wires just above the exhaust manifold. It took about 5 minutes to do this. Their claim was that if the oil ignited on the manifold, it would then ignite the plastic raceway and spread to the rest of the engine and vehicle. By removing the raceway, the danger of spread was eliminated. GM AND NTSB were responsible for this weak and lame repair. The required fix should have been to fix the cause of the leak--that being the valve cover gaskets and seals.
Quote from AutoBlog addressing the original recall:
The recall affects various Buick, Chevrolet, Oldsmobile, and Pontiac models equipped with normally aspirated versions of GM's much-utilized 3800 3.8-liter V6.
Apparently, some of these engines can drop oil onto the exhaust manifold during hard braking. If that manifold has gotten hot enough and the oil dribbles below the heat shield, it can start a small fire. The flames can then engulf the plastic spark plug wire channel, potentially resulting in a full-on engine compartment fire.
The fix? Dealer service departments will be asked to remove said spark plug wire retention channel from the front of the engine bay, and then retrofit two new retainers.
I don't know if they removed anything from the firewall side of the engine, but I do know that there was only one raceway cover laying in the trunk of her car when I got it back home. I searched and couldn't find a cause or cure for the current recall.
Edited: One of the Georgia Fiero members just posted on our forum and the problem is still the valve cover oil leaks on the 3800 engines. GM hasn't decided how they're going to eliminate the hazard and until they do, they are again recommending the vehicles be parked outside away from the home.
