This might sound dumb, but what benefit do you get by removing the EGR? I know they are a pain and have gunk up problems. I was just wondering if I should get rid of mine.

 

there really is no benefit or loss from it, the only thing is that to get rid of it, you have to custom make blanking plates, and then you will get a CEL because you computer will be looking for an egr and it won't be there.

 

Thanks, I saw you talking about it on the other thread and did not want to bust in.

 

Haha, but yeah, I would just leave it, it's just a bunch of extra work for nothing really.

 

sounds like a plan then, stay with EGR.

 

Yay egr!!!

 

I am not sure about Volvos in general on this, but I know that many cars rely on the EGR system to keep exhaust valve temperatures down and prevent them from getting burned. I know that a number of vehicles are susceptible to valves burning if the EGR system isn't working, and that some of those cars rely partly on the backpressure from the catalytic converter to help open the EGR valve. I had a friend with an old POS Grand Am that I fixed burned valves on 3 times- all 3 times, we had the head sent to a machine shop to be redone (this was YEARS ago!) before I found out that the catalytic converter had been "cleaned," I.E. emptied out, and that that was preventing the EGR from opening. Once we put a cat on again, he stopped having trouble with it burning valves. So...at least on some cars, the EGR system is VERY important, and definitely doesn't hurt anything.

 

I would say to leave it, but in 1996, Volvo eliminated the EGR completely. Otherwise I would say leave it, but the majority of 850's don't even have it.

 

My '96 N/A still has EGR - which plugs up and causes grief. Neither my '94 N/A or the '96 turbo has EGR. It all comes down to the emissions code.

Oh boy, now I am not sure. I just pulled the head do to a burnt valve, but tech said to run premo in the tank to avoid future issues. Not doubting, you tech, just wondering.

 

There is a ton of 850's out there with the EGR deleted and no problems.
Also like already stated the 96 Turbo's came without EGR.

 

If it ain't broke, don't fix it.
