[DML] Re: Not passing emissions



Matt,

What about that oil in the tubes below the air intake valve... You 
have two tubes. As you look at the engine from the rear of the 
car... One going to the left and one going to the right directly 
below where your air goes in. (John S took a picture of it). The one 
on the right had oil in it. Could that be a problem?
