Hello, My air dryer purge valve was stuck open for many months. I finally pulled the air dryer apart and found layers of muck, oil etc. I ordered a new service kit from my local dealer, however I can not get the purge valve body to come out. I removed the retaining ring and even applied compressed air it, it moved a 1/4 an inch but will not come fully out. Anyone familiar? Thanks Bill
Hope to be helpful.
