I'm poking around the top end of my Formula's 2.8 as discussed
HERE, and among other things I've discovered that my EGR tube was completely plugged with "tar" where it connected to the underside of the upper plenum. Although this angle doesn't show it very well, the tar ball was protruding out of the plenum at least a quarter inch into the EGR tube.
As you can see, the EGR tube is also cracked, and I need a replacement. Rodney sells new replacements and I may yet go that route. However, what's at the wreckers? We all know that the EGR tubes from 2.8 Camaros and Firebirds work well (they're actually tougher than the relatively fragile OE Fiero EGR tubes), but what about something like the following? I saw this EGR tube on eBay which is listed as being for a 2000 Cadillac Deville. Anyone seen one of these in person? Would it work with a 2.8 Fiero, specificlally an '88 which takes a slightly longer tube than the earlier years? Or does this one look
too long?
I'm just interested to see if we can find replacement EGR tubes from other sources. The more choices the better.
