I dread to think how messy the top of the engine is.

Here's some pics anyway.



The mixer pipe is the metal 90deg pipe in the right of the image. It was well caked in slimey black sooty cr@p.

Also the inlet into the top of the engine was thick with the same gunk.

Prior to removal


After removal


The EGR inlet hole (I think)

This is the common point for people to blank off the EGR.

And after a good clean up




Cleaned it up using carb cleaner and a LOT of kitchen roll. If you're going to do it invest in some latex gloves as it's a very messy job. Also tried as best as I could to clean out the top of engine inlet pipe and managed to scoop out a lot of mess with my fingers then cleaned out with carb cleaner and kitchen roll. It would really mean taking the top engine cover off to clean out properly but this would take a lot longer and mean messing about with the fuel lines, couldn't be bothered with that.

Easy job, just need a screw driver for the jubilee clips, takes an hour max.

The car seems to run a little smoother now and throttle response has improved, not a hugely noticable difference but it can't be good for the car to have all that horrible gunky cr@p in there.

For info my car is a 2002 V70 D5 on 103k.

The question is, would blanking my EGR valve prevent this from building up in future? I'm tempted to leave it be as the car runs fine as is.

Thank you for the photos. I feel hesitation from the engine around 50km/h and a few users mentioned this may be due to a dirty/clogged EGR mixer/valve. Is there any chance someone has a detailed description with photos or video on how to access the EGR?
Thank you.
