Does EGR go through Turbo?
Heavy-Duty Engines The EGR system is a high pressure loop (HPL) system where a portion of the exhaust is taken from upstream of the turbocharger. The EGR then passes to the intake manifold where it mixes with cooled charge air before being inducted into the engine.
Will my car run without an EGR valve?
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. As time goes by, the EGR valve may cause certain malfunctions in your diesel vehicle. …
Where are the EGR Jets in the intake manifold?
A more radical design, implemented in a few models, was the replacement of the valve with EGR jets at the bottom of the intake manifold. Some newer high-efficiency engines, for example those with variable valve timing (VVT), don’t even use an EGR system. If playback doesn’t begin shortly, try restarting your device.
Can a blanked off EGR improve engine performance?
Of course its not. The EGR pumps warm used air back into the engine instead of cold clean air. If you were to blank of the EGR, it would continuously get cold air thus an improvement in performance. For people looking for the best performance upgrade (such as myself), a remap with a blanked off EGR will provide excellent results.
What causes an engine to have a bad EGR valve?
and various engine sensors. An increase in hydrocarbon emissions isn’t necessarily caused by a stuck-open EGR valve. Problems in other systems may cause this same symptom as well: a leaking fuel injector, bad ignition timing, bad cylinder compression, bad oxygen sensor, or other problems.
How to clean a blockage in an EGR battery?
You will need to clean the EGR valve of the blockage using the following steps: 1 Disconnect battery 2 Remove sensors or clips 3 Loosen bolts holding the EGR valve 4 Use a EGR or Carburetor Cleaner to spray the valve and hoses 5 Reconnect the battery
How does faulty EGR valve cause turbo failure?
The valve ensures the EGR system is disabled at idle, when it would otherwise lead to erratic idling, and at peak power, when adding exhaust gases would reduce power output. The EGR valve is likely to stick and become coked up on some applications. BTN Turbo warns that this can have a significant effect on turbocharger performance.
How does the EGR tube work in a car?
The EGR tube acts as the main passageway of the EGR system, directing the exhaust gasses produced by the engine’s combustion from the exhaust manifold through the system, eventually recirculating it back into the intake manifold and back into the combustion chambers and the air-fuel mix to be burned again.

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.
