what benefits do you get from blocking off the EGR, and how do you go about doing it the right way?

 

This is going to start huge arguments here haha. But one benefit is the intake stays cleaner without exhaust gases flowing back into it. And if you have egr problems, a blockoff plate is much cheaper than replacing the components. An egr itself can be pricey, along with the sensors and everything else. All I did was put in an aluminum plate between the egr and intake, and plug the vacuum line at the tree. Leave the sensors plugged in and there won't be any active codes. There isn't for me at least.

 

The egr is a relic from the carb days, it enriches the fuel air mix to cool the combustion temps that cut out the oxides of nitrogen. A good electronic fuel injection can do the same thing just by increasing the fuel slightly.

 

I have mine blocked off i just took it off and welded a nut in the hole then grinded it down plugged all lines back it throws a cel at all times but i can tell a difference

 

Keep the EGR, remove the smog crap.

 

^ I agree with ditching the smog. I got rid of both though. The only emissions component I have left is an o2 sensor. I got rid of the cats, egr, and smog pump.

 

Subcribing do to interest in blocking mine off too.

 

What benefit/risk is involved in "removing the smog crap?" What do you do, just plug the AIR pipe and remove the pump, put on a shorter belt?

 

I'm putting on a shorter belt and removing the pump this weekend, but for now I still have the smog pump in place, but the inlet and outlet pipes are disconnected from it. I had the exhaust redone and had the piping coming off the exhaust removed, and plugged the hole in the intake with a large bolt. I removed all the solenoids and sensors for the smog pump also. It does register a code when you run a diagnostic scan, but it is a background code and doesn't make the check engine light come on.

If you plug the intake and exhaust properly, there is no risk.

 

The benefit for me was having less stuff to go wrong. If you do away with a little emissions stuff, you might as well do away with all of it.
