Okay so I've read all the info on the EGR Valvle diy here:
http://home.comcast.net/~em-engineering/T2T013.pdf
I totaly understand it and know what to do but I'm confused on one part. It says "After using a pick or a drill bit to break the carbon loose, use compressed air and carb cleaner to make sure the port is clear." and it says "Use a pick or drill bit to clean out the passageway. Go straight down and be sure and clear the hole at the bottome of the runner."
Now there is no way they picked all of the carbon crap out of the whole, reading it I assume they want me to knock all the carbon into the whole and clear the bottom of them, then re apply the valves. This confuses me because I would think knocking all the carbon crap into the pipe area of the intake manifold which I'm assuming enters the engine would be horrible for the engine. The only thing that caught my atention was when they said this is where the exhaust gasses enter, so I guess the exhaust goes into the intake manifold which would mean the carbon would go out the exhaust wich is fine but I find it hard to beleive that exhaust goes back into the intake manifold, I thought it just sucked air into the engine and then out the headers, which would mean the carb crap going into the engine and most likely staying there. I could be wrong but if that is what happenes then wouldn't that do damage? or maybe it is exhaust and it's fine..
Can someone clarify for me please and explain how it works? Thanks guys
