I have been wanting to block off the EGR on my Diesel.

I thought about making a couple of block off plates one for each end. Then my EGR unit could be removed and stored away. I decided on a more subtle solution. I made a single block off plate and put it at one end of the flex tubing. I shaped the plate and put it inside the flex pipe at the coupling and just reassembled it.

The engine has much better low end power. Is the turbo spinning faster? Will it help my economy? Might not. After all some of the power that I can get is from the unburned hydrocarbons which are no longer being circulated. I am guessing that the system was not functioning as designed. Seeing how black the intake manifold looks around the egr port makes me realize how much carbon has been blown through the engine.

Here is the disk.

I made it from some 20ga standard steel that I got from a friend who is a fabricator.

I still don't have my boost gauge, it should arrive in the next few days. I don't have an EGT either.
