Are you talking like block-off plate or what? Other than that only option I could think of would be headers. I just disconnected mine, simply unplugged it and no more EGR. for some strange reason it was giving me KR and causing all kindsa tuning issues, so we just unplugged that sucker.

If you mean removing it. There's 3 bolts if I recall (possibly 4) the line for the exhaust gas to pas through has a bolt on the headers (13mm) and a bolt just under the TB on the LIM (13mm). Once those are out of the way, if I recall there's 1 or 2 more under the EGR canistor (13mm). Then lastly two 10mm bolts holding the black shroud around it.

so...you can still run stock mani's even after removing the EGR? I coulda swore the EGR tube was welded onto the flange for the manifolds, didn't realize you can just unbolt it and be done. Dont have to have a block off plate?

Instructions: Unplug EGR valve from wiring harness. Unbolt EGR inlet tube from exhaust manifold (13mm). Unbolt EGR outlet tube from lower intake manifold (13mm). Unbolt two bolts holding the EGR valve pedestal to the head (13mm or 15mm). Remove entire EGR system from engine bay! Finally, find a way to seal the two holes you have just exposed. You should have something that looks like the picture below. Notice that the inlet tube is cut. That's how I got the collar off (it had a leak next to the inlet, anyway).Image

You'll have to either make or buy block-off plates or have the holes welded shut. Nate, don't you remember how I did mine? I placed a penny in the old retaining collar to cover the hole from the exhaust manifold and RTV'd it to make sure it would seal, then I bolted it in just like the original EGR inlet tube. Next, I made a block-off plate out of a piece of sheet steel to bolt to the LIM. Put a little RTV around the hole, and bolt 'er down! Of course, now I have the hole blocked in the blower casing, too.

Seems simple enough. I got some metal pieces around I could fabricate a blocking plate using a dermal.

Probably already melted seeing is the headers get quite a bit hotter than a penny's melting point haha

I actually still have my EGR still on my car and functioning. The only thing that's different is that the rear tube is not hooked up to the back header so that it's just sucking in clean air. Doesnt throw any engine code.

Actually, I checked it last time I changed the oil and it's still solid. :D

It just stops from the build up of carbon from exhaust fumes in yer intake/ s/c inlet. When I swapped back to Gen 3 a few weeks ago, my stock blower, LIM and TB were caked in nasty carbon/sludge. Idk how i ran a 13.4 last year w/ that stuff.......but thats when the EGR was hooked up its whole life. I cleaned the shit out of all that stuff b4 i put it back on and it runs awesome. Very noticable difference once you clean that stuff out of the blower and LIM. And now like i said my EGR is there and hooked up to my LIM but the rear tube is hanging in mid air...so that it's just sucking in clean air into the LIM.....and keeps the PCM happy. No codes.

All that carbon build up inside the motor over time is prone to heating up....wich will give you more KR. You might lose 1mpg from delieting the EGR............but the benefits from it are well worth it....knowing that you arnt pushing all that carbon shit back into yer motor. I still get over 30mpg on the highway w/o the EGR.

Gotcha, I might as well remove mine while I have my engine torn apart.

Or do what I did and leave the back hose hanging in mid air and block off the hole on the rear manifold. That way when you get NYSI and they look under your hood they see that the EGR is physically there if they wanna be pricks about it. That's the reason why I have mine like that.

I was reading online that if you remove the egr that the PCM will set itself to a lower ignition timing. I think grand prix fever's idea is the best.

I've never heard that b4 honestly. But like I said b4 the only reason why i have it the way it is is so that it will Pass NYSI and is completely functional........if i were in a state that didnt do inspections still it would be off completely.

I never had any issues with the PCM lowering timing when I removed mine, granted mine's a '97, which seems to be the exception more than it is the rule... With a tuner, you could tune around that, if it was the case. You'd have to have the code turned off anyway, so while you're getting that done, you can get a tune to maximize timing.

I used tin snips...and then threw the thing as far as I could out into the yard.

Might not be what you want to do though, lol. Seems like these guys covered it pretty well though.

I just used the tuner to set the EGR enable temp to a temp that will never be obtained, and therefore will never enable the EGR. You'll pass a physical inspection easily this way.
