what have you fellas used to block off the EGR port on the intake manifold when you remove the EGR system?
the headers came w/ a plate to block off the tube at the #2 primary, but im wondering about the other end at the manifold. thanks, CHIP

 

You can use a rubber freeze plug, but I cant remember the size. I'm sure someone will chime in.

 

I got an egr delete plug at the dealer, think it was about $15...Thunder racing sells them also I think. I'll see if I can dig up the part #'s...

 

I think this is the part# for the manifold plug: 12558346 $17.10 (got a discount...lists for about $24)

I got the EGR block off and gasket for the headers from Thunder Racing
EGR Stainless Steel Block Off Plate: 99-86EGR $10
GM LS1 EGR Valve Gasket: 20-1255304 $6.09

 

i think the plug size is 1 1/4

 

cool, thanks man. ill stop by the dealership on my lunchbreak tomorrow and see whats up. so its just a plug, dont need another gasket for the manifold?

ive already got the blockoff plate and gasket for the header. CHIP

 

Yea, when you unbolt the egr pipe from the manifold, you use the same bolt to hold the plug in...it's a little metal plate with a sort of o-ring on it, if I remember correctly.

 

I'm cheap, I used a piece of gasket material, and gasket maker (silicone). Total cost $0.00

 

Budhayes3....the part number you gave me was right. ordered it from the dealer today, $12 and change.

white1...i thought about making a piece, but i'd rather have something i wont have to worry about leaking. dont want to be bothered w/ a vaccum leak.

thanks fellas, CHIP

 

Was there anything that you guys did as far as tuning?? Why did you choose to do this? I ask b/c I think I may need all the room I can get in the engine bay
