75 CDT Liquid trapped in EGR after cleaning
 

I recently removed the EGR valve and inlet manifold from a 75 CDT parts car to clean and fit to my regular 75. I got the impression on the forum that it was a nasty job (and it was), so I soaked the parts in both diesel and soapy water (separately) for several days in between high pressure washing the parts.. Don't know if the soaking did any good, but the parts seem relatively clean now :}

Anyway, on to the problem: there is now some liquid (diesel and/or water) inside that little turret on the EGR where the vacuum hose connects, which I can't get out.. I managed to shake out most of it, but I can still hear that there's a little more left. I tried to blow the rest out with air, and some did come out, but there's more left. Anyone got any ideas? It will take forever to evaporate naturally, so I considered putting it in the oven on low temperature or something, but then I fear the kitchen and oven will smell of diesel afterwards.

I'm wondering if anyone else has had the same issue after cleaning the EGR? Do you have any suggestions, or do you know if it's safe to fit the EGR without it being completely dry?

I'd fit it, leave the vacuum pipe off for a few days (blank the hose with a small bolt) and the under bonnet heat will dry it out, then reattach the vacuum hose if you want the EGR to work.

If the water is on the EGR side of the diaphragm, the movement of air in the inlet manifold will dry it out anyway. Either way the water will evaporate.

The pipe should of been blocked off with a bit of fuel line/hose and a screw in the end to stop any fluid entering, bit to late now hopefully it will dry out

I read it as water is in the control side which won't evaporate by the action of air flowing through the EGR valve.

Great suggestion, thank you :}

I didn't think it would be that hard to dry it out, but I agree that's what I should've done. Also there's another small hole that would need to be blocked.

I don't know what you mean by diaphragm or EGR vs control side, but there's really just one place for the water to be trapped, no? Or is the "turret" as I call it (if you understand) split into two sections? I'm not familiar with the contruction of the EGR.

The control side is where the little pipe connects to the EGR valve. The little pipe carries a vacuum which moves the diaphragm (the circular bit) which in turn open/closes the EGR valve. Hope that is clear..

It is, thanks!
