To anyone that might be interested, I had to go and get my truck emission tested today. I passed with no egr hooked up, no charcoal canaster and connecting lines, and no pcv system hooked up. The numbers on the sheet were less than those of the last test two years ago. I was really suprised because I really didn't think I'd pass. No I can go ha, and give the emissions people the bird.

 

If you don't have the PCV system hooked up you are just screwing yourself, by not venting moisture and other acidic byproducts from inside your engine. I don't know your state but emissions tests usually have no way of looking at the charcoal canister or the pcv system. As for the EGR I believe it doesn't work at idle speeds anyway and unless your state has a dynomometer /treadmill test for emissions like mine does it won't be seen anyway. Of course I could be wrong .

In CA, they would have failed you for visual inspection because the EGR and the charcoal canister isn't hooked up.

stractor, you're right. They need a dyno in order to test the EGR.

 

I'm glad they don't check under the hood. Their loss, not mine.

 

"stractor, you're right. They need a dyno in order to test the EGR."

They only test for functionality, if it opens with vaccume applied, etc... as you say they need a dyno to test if it actually works the way it's intended.

 

And your point of having all this not connected WAS-------???????????
How much Horse Power did you gain??????? Do you realize that unless you disconnected it , there is a canister purge solenoid in the evaporative emissions system that opens the vacuum from the intake manifold to the carbon canister and as such will cause a vacuum leak to the atmosphere when the computer calls for it to open if there is no canister. That is unless you disconnected it.
Also----- EGR is there for a reason and on a stock engine there is no reason to disconnect it, you aren't going to gain anything. And as for the PCV system --well !!! I wouldn't be surprised to see moisture mixing with your oil.

My point was to get rid of stuff not necessary. There was never any plan to gain power. All vacuum ports, lines, etc. are plugged or capped in a way. The engine idles perfect with no engine shimmy, therefore no vacuum leak. The purpose of the egr is to cut down on nox emissions and the emissions testing place here does not test for nox. Once the engine is up to operating temp, all moisture should be burned off and pushed through the top openings in the valve cover, along with other by-products. My truck sees highway operation about 5/7 days of the weak and is there for about 20min, so it should get plenty hot to burn off moisture.
