Has anyone ever pulled off the intake manifold on a diesel to clean it? At how many miles? Is this service recomended by MBZ? Did you actually notice a difference?

I have never heard of it. Why would the intake be dirty ? It's just filtered air unless the seals in the turbo are gone or there is excessive blowby going thru the EGR valve. It both cases you would have bigger problems than a dirty manifold.

We have pulled the crossover pipe and cleaned the EGR area of debris. It is very common for the 603 to devlope alot of carbon there and for that carbon to break off and kill an engine.

Benzmac knows what I am talking about. Any pointers on cleaning this out. Have you ever tried a "engine vac"?
Thanks Benzmac! |

This crossover gets caked half inch thich at times. I can't imagine cleaning it chemically on the car. We usually take a chisel to it with the part off the motor.

Visit the following web site. You will find a section about cleaning the intake.

I took the intake manifold and crossover pipe off the car at 220K and took it to a machine shop. They soaked it in cleaner and a day later like new. It was caked on there pretty good. Plugged the egr to prevent this in the future and runs much better. Also replaced the intake manifold seal bc it was leaking due to time and sludge accumilation in the manifold. It cost me $30 to do, I recommend it.

Does anyone else have directions for cleaning the crossover pipe and intake, aside from the website that was previously mentioned?

I did see the article in The Star, does anyone else have anything else they can tell me that will help. The car runs fine, but this is more of a preventative maintenance item for me.
