Proudly entering my 3rd year of MJ ownership and I've stumbled on a mysterious disconnected line at my EGR. Long story short, after a 200 mile trip with my MJ, I discovered an oil leak dripping from the area of the drivers engine compartment near the air box. Two areas of consideration: 1) A disconnected vacuum line at the EGR. The connection at the top of the EGR Transducer is gone (?). I'm curious if a connection actually exists or if its just a plug. The disconnected line is pictured at the TOP of the transducer in this photo. My transducer's connection is broken off and there is no hole there at all. 2) My air filter was drenched in oil. So this brings to question... 1: Why did oil present itself in my vacuum system after this 200 mile trip. 2: Is there an actual connection back into the transducer? Thanks!
