While checking my DV i noticed that the pipe coming from the " vacuum reservoir " that sits above the 4th coil pack that goes to the n249 valve(or whatever silly number it has) goes from a rubber pipe to a plastic one for a bend... where the bend is looks over cinked and where it goes into the rubber just before the valve doesnt look sealed.
If this was a boost hose ( one of the big ones ) using soapy water in a spray would show this ... But arent these vacuum hoses arent they? How can i check if its leaking???
