EGR Disconnect
I would like to disconnect the EGR on my 79 SD. I have done a search through the archives and feel justified in giving DAS BOOT a break from the soot. Can anyone comment on their experience running with the EGR disconnected?

If you have done a search, you know what I think on the matter. Since the nix I have been getting better fuel mileage and more performance plus my engine is intaking clean filtered AIR like God meant it to.

mccan,
It is easy to disconnect the EGR--just pull the hose of and put a golf tee in it. Experiment for yourself and see the difference. I've experienced a slightly better acceleration, and about 2 more mpg. I even got a smoother idle. |

Sure enough, Bill. I had to trek out in the cold in my PJ's in the middle of the night with a freakin' flashlight to check. No EGR on the 79. Nevermind...

I think I'll wear it as a badge of distinction - "Yep, I've got one of the pure models, before they started monkeying around and pumping soot into them."
Although I was hoping to do something simple that would make a big improvement. I was all set to feel like a real mechanic. Oh well... I did pull the hose and bolt connecting the intake manifold to the overboost protector. Not very dirty really, but a bit of oil on the bolt. |

I wuz all confuse-alated I have a 1980 240 D with an EGR intake, but the car came with no air cleaner. So in my quest to find an air cleaner, I found that the engine was apparently an 82 or 83. Couldn't find an air cleaner to save my life, so I bought the two manifolds and matching air cleaner, and hey presto!

EGR plugged, does it work?
Greetings All,
First off, I'd like to keep the Benz as original as I can, but with all the debate over the EGR valve either being vacuum removed or a plate put in it's place I'd like to know the benefits besides throwing dirty air into the intake? In a gasoline engine this removal would have a detrimental effect because it generally is hooked to vacuum lines and several other items like shift vacuums etc. Is there anyone out there that has honestly gotten any improvement from the EGR inop plan. If you have, what is the best method of disabling it besides just disconnecting the vac line. I could see replacing the valve with a plate that restricts any air flow to this item to prevent carbon caking on it. Is this the general concenses? Plate the valve closed and leave the vac plugged? Charles
