Welded EGR valve???

Quick question... If I weld my egr valve closed, will it cause any damage if I run it for a while without completely blocking the cooler or removing it? I am going to do the egr cooler delete soon, but $$$$ is real tight right now.

Just unplug the sensor. May throw a code on the '04's - some did - some didnt. That in itself will tell you what to expect as a basis. Consider the DIY full EGR delete here on the forum found under the Mod Help section. I had this done to my '03 for about $50 total. Awesome results! Cheap too!

What happens if you don't unplug the sensor and weld it? My other issue with deleting the cooler as opposed to blocking it is that I have to have emission tests done every other year or so. not sure if the cooler is something they look for or would even know if it was gone. I saw the write up on it and am seriously considering to doing it if I knew it wouldn't bite me in the arse later.

Thanks for your input!!!!

The EGR cooler still remains a problem potential even if it is blocked off. It continues to flow coolant and can still ruputer and leak. If you are subject to emissions and want to keep the EGR cooler and fix the problem for good replace it with the cooler from Bulletprrof Diesel.

Then just unplug the EGR valve. This is the cooler that Ford should have designed. Personall I favor the full delete but if you can't or don't want to....

aside from rupturing or leaking, will it do any damage to the motor? Is it really necessary to unplug the valve if it is welded shut?
Thanks for you input!!

If you have the early version of the EGR cooler, the odds of it failing are pretty slim. The early version is round tube-shaped, the newer version used in 04.5 - 07 is square.

So IMO, if you have the early version you could just as well leave it be till you're also ready to plug the exhaust influent or totally delete it.

YOU MUST UN PLUG IT WHEN WELDED SHUT!
it will still try to cycle and over heat,i welded mine but i have the tunes to have it inoperable

Now this was a superior machine. Ten grand worth of gimmicks and high-priced special effects. The rear windows lit up with a touch like frogs in a dynamite pond. The dashboard was full of esoteric lights and dials and meters that I would never understand.
