[DML] Re: Good news for vin 2277 AT LAST!!

I tried the screwdriver method but I can't be sure about what I hear. 
Funny thing is that the sound is really only pronounced when the 
engine is warm. When cold it's barely audible. Perhaps the gaps loosen 
up a bit when the motor gets hot? (at least thats what I want to 
believe!) I would think an exhaust leak would present itself hot or 
cold. Thoughts?
