The forum is meant to stimulate interaction among Crossfire owners and pass on information that is useful and informative. Jumping down another members throat because of a simple post may well be one reason female members rarely post. I am surprised she didn't respond to your attack, but she is probably too much a lady.

"I owned a Fiat Spyder that this was done with" - "The engine had to be replaced" - "could be an expensive test" - maybe you should go back and read her posting. She gives no prove that her engine came apart because of an EGR problem.
No one makes claims that I am posting an engine mod that will blow your engine up without demonstrating with facts. That is BS and not an over reaction on my part.
Now if you can Google the net and come up with any engine that destroyed itself because the vacuum hose was disconnected from the vacuum valve that opens and closes the EGR valve - I'll gladly eat my words by way of a video feed to this forum. Hooah

"EGR Valves have been around for a long time. Starting way back in 1972 GM used them in an attempt to reduce emissions of oxides of nitrogen (NOx) which were a major cause of air pollution, mainly photochemical smog, that kind of smog which is formed when strong sunlight shines down on the exhaust gasses we puke out of our tailpipes by the billions of cubic feet a day.
A short chemistry lesson is in order here. It was discovered way back when, that high combustion chamber peak temperatures (the really short duration high temperatures near the end of the combustion process) caused oxygen and nitrogen to combine chemically and form these oxides of nitrogen mentioned above. Most of the anti-pollution devices of the day did a pretty good job of reducing the other bad by-products of combustion, namely excessive hydrocarbons and carbon monoxide, however they tended to induce the formation of oxides of nitrogen. Something had to be done else we would all die of smog diseases.
The automotive engineers figured that they needed to do something to lower the peak combustion temperatures which only occurred under certain high load driving conditions. They figured they could do so at the expense of power and fuel economy but what the heck, ya can't have everything! If they could only add something to the combustion chamber that would act like sort of a fire extinguisher to cool the combustion temperatures that would do it.
So they invented a way to allow some very inert gas to get back into the combustion chamber only when needed. They needed a source of this gas - it wasn't air, cuz that contains oxygen and nitrogen which caused the problem in the first place. So they chose carbon dioxide. Where to get a supply of carbon dioxide . . . ??? Hmmmm, how about the exhaust system? That is mainly carbon dioxide and water (plus a zillion other noxious chemicals) Suppose we allow some of the exhaust gas to get back into the intake manifold under strict control and only when we need it? That would cool the combustion chamber and prevent the formation of the NoX. Maybe we should call it recirculated exhaust gas (REG??). But a guy named Reginald voted no cuz he didn't want his name associated with a car part, so they called it exhaust gas recirculation (EGR) since there was nobody around with that name.
Now we understand why it is there. And we understand what it does. So what can go wrong with it and what are the symptoms??
It's really pretty simple - it can be open when it isn't supposed to be, or it can be closed when it is supposed to be open. Not rocket science, but it is science. If it is open when it is not supposed to be open, at idle for instance, It will act like one monster vacuum leak and the engine will not idle or will idle really roughly. If it doesn't open when it is supposed to open you will probably experience a symptom of "pinging" or "knocking" since the combustion chamber temperature will be higher than normal (one of the main causes of pinging in an engine).

How many of you folks posting in this thread, short of Wayne, know what a EGR Valve looks like, or where it is located, without doing a "Google" on the internet?
How many of you know where the "Smug Pump" is located or looks like without using the internet for a brain?
Just wondering if I should continue to defend my position, or if I'm dealing with "Net Kiddies." hooah
Re: Here is a free HP increase for your XFire...
I see by your profile you are just a few years older than I am. I understand that you are also a Vietnam Veteran and I commend you for your service to your Country. Although I am a woman and may not be as experienced as a mechanic; I am perfectly capable of following instructions. When I need to solve a problem I find that Chilton Books give a fairly good "How To Do" when it comes to automobile repairs and troubleshooting. I also remember the "OLD DAYS" when you could walk up to an experienced mechanic and in five minutes he could troubleshoot the problem and recommend a fix. Good luck trying to find anyone that can do this today without computer diagnostic equipment.
Once again, in reference to my post. The 1976 Fiat Spyder had a double overhead cam and was adapted from a former Ferrari engine by Fiat. It was a high revving engine that could easily tach out to 7,000 rpm. It was one of the most durable engines available. A friend of mine ( a mechanic) attended a school in Italy known as FAZA. This organization specialized in tuning and enhancing Ferrari and Fiat racing engines. He bought a kit that disconnected the pollution control; disconnected the EGR valve and plugged the vacuum lines associated with these items. (to prevent rough idling and flat spots on acceleration). The Fiat ran fantastic. A noticeable increase in power and performance. There was no other changes made to the car. Within a week I noticed the temperature gauge increasing substantially. By the time I got the car home it boiled over. On checking the oil I noticed it had a milky appearance. A blown head gasket.
My friend and an expert import mechanic replaced the head gasket. The oil and filter was changed and ,five minutes after the car was started antifreeze appeared in the oil. They removed the head and found it was warped and beyond machining. They replaced the entire assembly. In analyzing what caused this, they determined that the Fiat engine used in Europe did not have all the pollution controls that the US engine had. So, by disconnection the EGR valve and plugging the lines; this caused a buildup of heat and pressure in the engine therefore blowing the head gasket. So I am not saying this would happen to every engine in every make as manufacturers use different pollution systems, all of which have changed dramatically over the years. I therefore resolve that one cannot say that disconnecting the EGR valve will either harm or not harm the engine. I am sure, however, that the computer will throw a code when the EGR is disconnected and attempt to compensate in some way.
There are some young men on this forum, (Bullseye for one) that are very up to date with today's technology, and always substantiate their claims with facts and personal experience. For some reason you feel personally attacked about this matter, and I assure you no disrespect was intended. In turn, you should respect other people's opinion and refrain from name calling and trashing their posts. I have found that to get respect you have to give it in return. Hopefully the WAR is over.

Re: Here is a free HP increase for your XFire...
As i said before don't stop, (but i think we have explored every avenue) it has been a very entertaining post, an i for one have learned a lot. The lady is right everyone's views and comments should be respected. That why we have a forum an that also has been said before.
Happy and safe enjoyable drive to you all. Don't forget we all drive an love our crossfires to bits THAT MAKES US SPECIAL AND UNIQUE, an 1 big happy family.
