EGR valve fix on Volvo D12D

go ahead and try it but when you get hauled into the inspection bay and they do a thorough inspection and find what you did you will wish you just got it repaired. More then likely your truck will be towed, you will be fined a hefty amount and then you could face license suspension too. Oh and how do i know this? I was a former state trooper awhile back who did inspections. We know what to look for. Now as a driver i know what not to do.

 

So you open the EGR valve and check what's inside?

I'm glad I don't live in USA.

 

don't know how they can check without opening up the EGR valves. I would say they can just use a "sniffer" on your exhaust, but with all the different year trucks still allowed to run NJ, dont know how they could do it

 

Smoke test is easy ,they can do that, but without EGR engines are cleaner so no problem. I have never heard about NOx testers outside engine laboratories so it's hard to believe they have one.

 

Not that I would ever bypass the EGR system on a diesel engine....I think it is a complete waste of time and effort. But there is absolutly no way this would be checked on a roadside inspection, or weigh station. You simply cant tell from just looking at the outside of the EGR valves (on a D12 volvo anyways).

 

No way they could check without removing the egr but there is a few sensors that are part of the egr systems and it might sedate the truck I stead of welding them u could just unplug it its the same effect and a lot cheaper but I wouldn't suggest doing either one

 

Check out pdqperformance.com. They can kill the cycling part of the EGRs. So u can remove the EGRs from the exhaust but they still have to be plugged in to the ECU. They also have a Blixxton 200 Volvo box that adds more power.
