i am sorry to bother you, i just have a question i hope you can help me with. i have read your write up on the EATC overhaul, it is briliant! i have ordered the rings, and i am going to repair mine. i was just wondering if you could explain a little more on how to trouble shoot exactly to make sure it is my problem in the first place, i would really appreciate it. i have the tool to pull a vacuum to test the lines i need to test, i am just unsure which to test and if it should or should not hold a vacuum..
