I have a 2006 Suzuki Reno. I have a slight oil leak it appears to be coming from around the egr adapter plate where the tube that comes the valve cover meets the bottom of the egr adapter plate. This is the model with the adapter plate that uses the 100 dollar gasket. Would I get oil seepage from that place or does that tube carry coolant or air. Just trying to find out before I tear it apart and buy a $100 gasket.
