Can blocking the egr port damage or hinder car performance

 

Yes. The egr serves to reduce combustion temperatures as well as reducing emissions. This can prevent detonation. It would be a very rare case, however, that blocking it actually did cause problems.

 

blah blah blah... just block it off with a piece of sheet metal

 

Do you know where a block-off plate could be bought?

Dolph,

I am sure that Jegs or Summit have the plates and gaskets.

 

sometimes I wonder about myself.....

 

lol dont beat yourself up to badly. I have my EGR blocked off I wasnt sure if it would be a problem. Especially with carbon buildup in the chambers and exhaust.

 

my digital egr valve sometimes backfires when rev dropping in neutral. i think one of the bolts broke and half of it is sitting inside the thread If i cant find a replacement at a junkyard, i could just block it off and everything *should* be alright?

"Who needs emissions anyway?"
