CM 2250 EGR Valve question, please help...

[ahub86]

Thank you rawze. Cleaning it did seem to slow it down. The bubbles yesterday were big really quickly and today they ended up smaller and slower to build. I know that’s not a scientific approach to it but that’s what I observed. It also was slower when the egr valve opened up. Same thing, it just looked slower to me. I appreciate knowing the 10psi in a minute rule, that will give me some more knowledge going forward with things. Glad to have this site to work with… this thread was the only thing that was useful to me on my google search. I don’t like to replace any parts before I can prove they are bad. So I am going with this one is ok. I took a video of it with the soapy bubbles on it, so now I have a baseline to refer back to while I keep an eye on things. Thanks again.
