I have heard that some guys blank off the EGR valve.
What is the benefit?
Better low down torque,
Better Fuel Consumption, etc.
What is the negatives?
Worse Fuel Consumption,
Battle to start on a cold morning, etc.
Where is the best place to blank it off?
Between the interconnecting pipe and the exhaust manifold,
At the valve actuator, or
At the intake manifold.
All three (3) these positions have the same size and the blanking off plate can be inserted at any position.
Will it be necessary to replace the thin steel gaskets at these positions after loosening the nuts and bolts?
Will there be leaks if the steel gaskets are not replaced?
