Default Re: Cleaning EGR Valve (with Pictures)

i restored my bad EGR valve with sticking valve etc...
I had used solvents but problem would keep coming back in a month.
finally, I thought maybe the shaft clearance was too tight causing a bind on the smallest amount of dirt. SO, i made a slurry of equate toothpaste, (use toothpaste with grit not gel), filled up the cavity, took a power drill and torx bit and spun that valve around till it was good and free. I have not had to do anything to it for about a year now.

My gasket eventually wore out so I just used some silicone gasket maker for the gasket. I whacked out all the slippery soft graphitic stuff out of the metal gasket and smeared some silcone into it.

REWARD EXCELLENCE!
