When did EGR valves become mandatory?
When did EGR valves become mandatory?
Registered. I am not a smog mechanic, but know that EGR appeared in the early 1970’s as mandatory emissions equipment. In Kalifornia, I believe it became mandatory for the 1972 model year on most cars, 1974 on trucks. Some years ago, I had a 1974 Power Wagon that dropped off the DMV’s registration records.
Where is the EGR valve on a Duramax?
Over time, the EGR valve will clog and will need to be replaced. Disconnect the cable on the negative terminal of the battery. Locate the exhaust manifold on the engine. The manifold will be on the right side, or driver’s side, of the engine, but its location will vary slightly depending on the particular Duramax model.
Why is the EGR Valve Bad for your diesel engine?
So when you reintroduce exhaust back into the diesel engine, you are displacing fresh air that has more oxygen with exhaust gasses that don’t. As a result, the engine doesn’t burn the fuel as well because there is less oxygen. Second, diesel exhaust by its very nature has pollutants in it, including soot in the form of carbon.
Can you blank the EGR valve on a Ford Focus?
If the EGR was fine, leave it be. If its playing up, replace. People only blank as a last resort on Peugeots because the valve is so hard to get to on some engines, and requires the entire engine being removed from the mounts and pulled forward. Ford Focus 1.6 TDCI – Blanking EGR valve and fault codes – Railroad.
Do you have to blank the EGR valve on a Peugeot?
EGR blanking is popular on the 110bhp 1.6 DV6TED (or variant on that code) diesel engine in Peugeots, but you need to have the EGR valve mapped out in the ECU and a remap, otherwise you’ll always have the light on. If the EGR was fine, leave it be.
Why do I need to replace the EGR valve on my Duramax?
This increases fuel economy by ensuring that all of the diesel fuel has been consumed. It also reduces emissions because it prevents the fuel from being released into the atmosphere. Over time, the EGR valve will clog and will need to be replaced. Disconnect the cable on the negative terminal of the battery.

Are there any disadvantages to using an EGR valve?
There are some disadvantages of EGR as well such as loss in fuel economy, low performance and, in diesel-engine cars, the production of soot increases. However, modern engines use clever technologies for an efficient process, for example, new diesel engines now use EGR cooler which cools down the exhaust gasses by passing the coolant.
