I am almost done installing my non-emission headers on my TA. I don't want to spend $30 on block off plates. Is there anything I can do to not spend it? Could I just crimp/seal the tube off at the bottom?

 

the lt4 blockoff plate is like 8 bucks and then all you really need is a couple rubber vacuum caps.

 

Cut a diamond shaped plate (you can cut it from a soda can) to match the flange on the corrugated tube, drill two holes in it so it will slip over the studs on the back of the manifold, then bolt the corrugated tube flange back on to sandwich the metal plate to the intake. A small amount of RTV on the manifold side will ensure a good seal. Cost.... "0".

 

Thank you.

 

Anyone have any pics of that kind of setup?

 

It's pretty intutitive. The aluminum can is just to seal it. You still need to keep the old piece to bolt on the back of it.

 

I bought the EGR block off plate from GMPartsDirect, but that only blocks off the EGR valve. I need to block off the EGR pipe that comes from the pass. side manifold. So all I would do would be to take off that plate...disconnect the pipe from the plate, then get the coke can, can put it behind the plate and place it back on the intake manifold?

 

I bought these http://cgi.ebay.com/ebaymotors/ws/eB...category=33607

They were perfect, fast shipping, nice guy. I will spend the extra money to not rig my cars with things like beer cans

 

I think I"m goign to go with that...what about gaskets?

 

You won't be disappointted What's 34.00.... F...it

 

Can you delete the EGR function via PCM reprogramming, without having to physically block it off?

 

I'm the guy selling the paltes form the Ebay link above. Thanks for the compliments I don't sell anything that I wouldn't be proud to put on my own car.

If you want them alittle cheaper email me and we can cut Ebay out and I can knock off $2 if you want. And about the gaskets, I don't think they are nessessary. When I installed mine over 2 years ago I used some RTV to make a small bead, let it set for about 10 minutes to stiffin alittle and install. I have had no problems at all. With the heat now taken off the back of the intake manifold you don't have to worry about the RTV getting cooked. I thought about making gaskets like some of the other guys are that are selling them, bet felt they wern't needed. I use .250 tool plate 6061-T6 aluminum and is very flat. So if you clean off the mating surface well, and use alittle RTV, there shouldn't be any problems.

 

Thats it? do I need to block anything else off?
