Finally got to drive my Fiero last night for the first time in a couple of months, and when I stopped for gas I noticed some white steam coming out of the driver's side engine vent. Opened the hood and it looked like it was all originating from a gasket in this thing in the center of the photo:

This images is larger than 153600 bytes. Click to view.

Didn't realize how bad the pic was till I got to see it on a larger screen than my cellphone, so apologies there. There appear to be two sets of screws and gaskets in whatever this is - one at the connection to the gold hard line/heat wrap going towards the engine (there was a bit of moisture bubbling at this gasket and where at least 90% of the steam appeared to be coming from), and another slightly farther up towards the plastic portion of it (maybe a little bit of steam coming from here, hard to tell). I couldn't detect any burning smell and there's nothing leaking down on to the rest of the engine or my garage floor. So what is this, and is it something that gaskets commonly fail on?

I think your referring to the EGR. Common for that tube to be cracked.

The EGR system has no water in it and is all under a vacuum, so nothing should be coming out of it.....do you see any coolant leaks at the throttle body?

From what I can see it looks like it might be a heater hose.

Mine had a little smoke from there when I had a cracked tube. It went away after I did an EGR delete. I assumed it was just exhaust gasses. It wasn't all the time. Just ever so often I would see it puff up. But I could see the coolant tubes for the throttle body be a problem as well.

It looks like the area around the base of the EGR valve got wet. After the exhaust gets hot, the moisture will start to boil off. The question is how the moisture got there. Did you wash the car recently? Does the steam smell like antifreeze?

put an arrow on the part you are talking about with ms paint and we could have a better answer for you, cause I see a lot of things there but not steam.

white steam from any vehicle usually indicates a coolant leak somewhere

Sorry, I'll take a better picture when I get home tonight and draw on it a bit. I washed the car a couple of weeks ago and then garaged it without driving it long enough to get the engine up to temp, but it seemed a little odd to me that there could still be moisture there. Like I said, no smell at all - just the steam. I doubt I'll be able to actually get the steam in the pic, it's not really thick or anything, but I can certainly highlight the gasket I was talking about.
