EGR Block Off Plate
« on: February 19 2020, 07:22:00 PM »
Hi All,
Question, When ordering this EHR block off plate, why are they sending a screw when the original set up is bolted down with a nut?  Or is every engine has a different factory set up?
My personal feelings, Forget about the useless screw just send a gasket.

Is it necessary to remove the threaded bolt? Why not use the nut?

Doesn't really matter either way.   Those block off plates (AKA 'reeds') are nothing more than POS's.

Yep, glued one down on the GN 20 years ago and it has been good so far. I have seen others that leaked on other cars. Must be the prep

Do you high temp rtv on both sides of gasket or just the side of the EGR plate?

Thanks, I wasn't sure if it was one side or both.
Today I drain the tranny fluid and it's a lot of fluid since it has a deep pan cover.
Tomorrow I will check the TV cable setting with the valve body plunger, I will post some pictures or video of making the GM style adjustment, and compare to see how close the plunger valve is at full wot
