they are a pain to get to and to figure out, looking for some help

 

Do you need the thread spec for the studs that are used to hold the EGR on, or are you looking for the wrench size for the nut (1/2")?

 

wrench size, for the nut, 1/2"??

 

1/2" wrench size.

 

I know this post is old but...

What about the thread size?

my guess would be 1/4" x 20 but i am not sure about length.

and would this be the same for both the valve and the pipe to the exhaust?

Can anyone verify?

Thank you

 

Hi,

I know this is a very old thread but I was wondering if you found out the thread size as the camaro I'm working on did not come with the two nuts

thanks
