Scrape out what you can, it'll make the job a lot easier. Get a big tub and soak the manifold in a strong concentration of degreaser, it'll soften the crap so it comes out pretty easy with a bottle brush. Wear gloves, it makes a mess. If all else fails, Kerosene works well.

When you're done, disable the EGR system if you want to keep it clean.

cons/pros to disabling? how would you suggest? plug it up or run it under the car?(rust prevention? )

regarding disabling the EGR.

Pros, runs cleaner. Better fuel mileage.

Cons, you won't get the privilege of cleaning your intake manifold in another 100k miles.

There is absolutely no reason to keep your EGR functioning. Contact ROLL GUY in this forum for a kit to disable.

$1000 fine if they ever start enforcing diesel emissions. Social responsibility not to pollute. Negligible impact on fuel economy or performance.

Most people don’t even know what egr is. Majority of cars 20 years ago and up don’t have it. I’d be shocked to believe that a cop knows exactly what to look for then cares enough to write paperwork on it. Egr has been nothing but problems and does very little for emissions

Really??? I doubt there is not one vehicle sold in the USA since the '70s that did NOT have an EGR, gas or Diesel. Most if not all newer Diesels also have an EGR cooler (as well as an EGR of course).

Neither of my Chrysler minivan gas engines have EGR. One is a 1996 2.4L "federal" and the other a 2002 3.8L CA. The CA one does have a special CA/NY catalytic converter. I think the same engines used in passenger cars did have EGR. Why not in a minivan? Because they are classed as "truck", and are thus allowed to pollute more. Congress decided not to "impact business" when they set the emissions laws.

I removed the EGR valves and clutter of vaccum/electric sensors & controls on my 1984 & 1985 CA 300D's. I don't think any of it worked anymore, parts weren't available, nor description of how it is supposed to work, so impossible to maintain. To demonstrate the absurdity of the Rube Golberg design, the AC compressor stopped turning on, which was because the OVP relay failed. It's sole job is to protect the (kludged-on) "EGR computer" from an alternator Vreg failure. That kills the rpm signal, which the KLIMA control box uses to decide when the AC compressor can actuate. I ripped all that mess out to0 and jumpered the rpm signal direct to the KLIMA.

ah I meant removing the CCV not the EGR. my non turbo doesn't have EGR. I was looking to route my CCV line under the car or something since I just cleaned my intake after new header/gaskets
