I have a leak somewhere between my valve cover gasket and my intake plenum on the drivers side. This being near the first drivers side inj starting from the front of the car. I cleaned the residue the other day with brake cleaner and rinsed with water to flush the crap away so I could locate where the leak is coming from. I ran it tonight and see some of it on the injector and near the EGR. Can it be from the EGR. I am pretty sure the car runs rich especially at idle since sometimes I can smell the gas from the exhaust and black crap(carbon) shoots from the tailpipes on my garage floor(Only at start up). Could it be that the EGR is leaking? I smelled the blackish liquid and it did not smell like gas.
