    Ok, I have read numerous posts about blocking the egr valve and egr cooler on the mercedes mbe 4000. I would like to try and tie all the information together. From what I can tell you can achieve this by useing frost plugs and machining a block off plate for the egr valve. As far as I can tell this can be done with no check engine lights or codes? If anyone has done either of these 2 things your response would be much appreciated. I am currently having to decide on replacing my egr cooler and valve at a cost of more than $2500 or just block them off and get on the road. Any info on this thread will help as I have been collecting lots of un-specific info from many different threads. Thank you.

    i have blocked the egr valve with a piece of aluminum pipe. so far i have gotten about 30000 miles on it and no issues yet. before i did that the water temp would run at 195, 198 consistently. with the egr valve blocked the water temp is at 180 degrees. i noticed that the truck has more power now and WILL NOT OVERHEAT. i have torn apart and redone the top-end of that motor 3 times; once by the shop and twice by me. so far so good. oh and dont try to get good fuel mileage from the mbe 4000 because it just wont happen.

    i hope this helps.

    The MBE4000 is just like any other motor ever produced, some guys love them and some guys hate them, some guys get 7mpg+ & some guys struggle to get 5mpg & no matter what brand of motor you have your always going to have some sort of mechanical problems along the way, so all you can do is just drive the #### thing or trade it off for something else.
