EGR Disabling, Good Idea?
Hey Guys,
I've heard people say that the EGR is a bad idea on a diesel and it should be disabled to prevent it from harming other parts. Is this true? If so, how can I do it? The vacuum cables seem to all be connected still. Can you just remove the whole unit and cover the opening somehow? Thank you, Nick

Nick,
Being an emission component, you pose a question that can be tricky to answer. Please do a search on the topic and you will find ways to disable and/or remove some vacuum lines for "off-road or test" purposes. What you do from there would of course be an individual decision. I have my '87 in test mode based on the available threads with the EGR vacuum components resting in a card board box. This is of course to see how they perform away from the vehicle.

I am not sure exactly what your looks like. I removed the tube from mine and cut it lenght wise. From that I made caps for the two ends.

Just what I hear
Long, Long time ago in a state far, far away I was informed that one could put a regular BB just inside where the vacume line connects. This would be for testing purposes only. Several years later I am still waiting for the results of this test.

The vac line going to my EGR got up and walked over to my tool box one night.

Just break that stupid peice of junk, your engine will thank you.
But remember this statement applies to MB diesels only, gas engines actually need there egr's. I think with a gas engine besides getting a CE light you could burn a valve.

Two questions:
1) Will removal of the EGR improve performance of ANY MB diesel engine? For this answer, the question of the legality of this procedure is a moot point, and doesn't apply whatsoever. 2) Okay, now it does. Is the EGR covered by Canadian law? Thanks, Dunl
