Wink EGR Valves Dirty

I asked a question without switching subjects and re-posting. I received no responses at all.


My friend checked the plenum yesterday, and it was hot by the #1 valve, and then I was able to find an egr reference in one of the poss I cannot fidn now, but it seems according to the post, if the egr metering valve is plugged, it can cause that, and make the #1 cylinder get all of the o2 or egr, and cause that to superheat.

This makes sense. I am however unsure how to clean out the intake egr thoroughly. I bought some mineral spirits, and a pick to pull out the junk. What else can I do to remove the build up? Canb I pour b-12 chemtool into the hole, and then re-start it?

BTW, I wanted to do the 0171 & 0174 fix back in January, but delayed, due to sub-freezing temps, and the fa ct my friend told me it was something else. I wish I'd done it earlier, and checked anyway.

Any useful replies would be appreciated. I have to wait until it warms up enough to do the work!
