YES it's sort of a tedious job, it's quite a it more work than replacing just the valve, for sure. That's why you want to really think about your plans for the car (couple more years? a decade? want to will it to your relatives?). Again the new pipe should "fix" the problem, the part that goes inside the intake is longer. Cleaning it out? That's only going to last awhile, my opinion is if the car is an 89, it took 14 years to plug up (assuming it is), it'll probably plug up again in alot less than 14 years, they won't be able to make it as clean as it was in 89 and it'll reaccumulate faster. This tube does run from the exhaust manifold on the right side (passenger side), around the rear of the block, and to about the middle of the intake manifold. Once you've replaced one 3 or 4 times you get the hang of it and can do it in maybe around an hour, hour and a half, those first few times were taking me I believe over 2 hours though. |

I just did this job on my 1995 C280 - 141,000 miles. The last 20-25mm of the pipe was plugged solid. I don't know how anything was getting through it and yet I hadn't gotten a code. I took Gilly's advice and replaced the tube. I did try cleaning it on the engine using Steve B's method and another suggested on this forum - a copper tube guide with a cable forced through on the intake manifold side. I wasn't satisfied that I did a satisfactory job. Replacing the tube is tedious, but there are worse jobs. One note, you can see the intake manifold end of the tube by blocking open the throttle plate and using a small mirror.

C280 Check Engine Light
It was the EGR Pipe. It was clogged.
I just took a digital photo and will post it (if I can) so others can see it. EGR valve was oK. Pipe cost $130. |
