Which one is #1 EGR?

When i look at the motor from the passenger side, which one is the #1 egr? The one towards the front of the motor? Or the one towards the back? Thanks for any help

 

Thanks. Will do. Found egr on sale at north carolina volvo for $550 if you need any

 

Shouldnt complain....this one lasted 4 years. A "friend" of mine found out that if you take an Egr valve and gut it, you find out some very interesting things.
For example....my "friend" took out the plunger valve that opens and closes the port into the motor, and cut the stem off. He then welded the valve closed. The egr will still actuate the motor, which turns the sensor to tell the computer thats its opening and closing, but no gasses get passed back into the motor.
Of course all this is illegal for use on trucks going into California, but legal elsewhere since the new smog laws arent in effect anwhere else.

 

Not that i would ever use it on a vehicle driven on the road. Nor would i suggest it to people to do, I merely said my friend chose to do that on his. Shame on him

And yes, you are correct....this sort of fix that saves my friend thousands of dollers, and makes his equiptment more efficient is illegal to do. My bad

 

I hear ya.
