any ideas on what to clean an EGR valve with?

What's a good solvent for all the gunk? Mineral spirits, kerosene, gas, nathpa, paint thinner, turpintine?

Mine is completely clogged. I picked a lot of crap out of it and got it opened up a little. But the gunk inside is very resilient.

I've tried soaking on degreaser, carb cleaner spray, solovents. But whatever it is that goes through the valve has built up real good and solid.

lightly tap it, on a hard surface, or use a small hammer. use a small screw driver to poke/break away the carbon, again, lightly!!

The TB cleaner/carb cleaner should be the last thing that you use after getting the big chunks
out. The TB cleaner will only work on light build -ups of carbon.......
Take your time.
Good Luck,

soak it in a qt of ATF that should eat up alot of crap

or just shelll out the $35 for a new one

ATF? Unusual suggestion. I'll try it. What is it about ATF and is it a good cleaner for other things?

ATF has a lot of additives that keep the tranny clean in use. It's these additives that wear out and require the fluid to be changed. That's a pretty interesting suggestion to use it as a carbon cleaner. Let us know if it works.
Orange cleaner might also work.

Personally I'd spend the $35.
