Can u drive without a EGR tube?
As per my research and going through the threads on EGR valves its OK to run without EGR. Yes it might affect the environment but no harm to engine as such. there are people who are running without EGR for more than 50k km. As time goes by, the EGR valve may cause certain malfunctions in your diesel vehicle.
Do you need an EGR tube?
You don’t need it. Your mileage will suffer though. The EGR system is used at cruising RPM’s so not as much fuel is needed. Without those inert gasses being drawn in, the computer will have to add fuel so the mixture does not lean out.
Do you need to replace the EGR pipe?
Even though the functioning of the EGR system may seem complicated, replacing the EGR pipe won’t be. You may need to remove various air intake parts to get at the EGR hose Then you’ll need to unbolt the EGR tube from the exhaust manifold and separate it from the EGR valve, unbolting it and disconnecting the associated vacuum hoses.
Why is my EGR tube not working properly?
The exhaust flowing through it can leave behind residue that builds up in the tube. The high heat of these gasses may also damage the tube, causing leaks. In either case, the result will be that the EGR system doesn’t supply exhaust gasses to the engine when it’s supposed to.
How does the exhaust gas recirculation ( EGR ) system work?
The Exhaust Gas Recirculation (EGR) system takes a small amount of exhaust gas from the exhaust manifold and pushes it into the intake manifold to help reduce nitrous oxide emissions.
