Head gasket pics

Haven't replaced yours recently, have you Eric?

Those are OEM PCV hoses.

OK, thought I remembered buying one recently that was black, but maybe not...

Sounds like a vacuum leak at the EGR valve. There is a metal gasket between the valve and the intake. It is a little hard to get on there because you have to remove the studs to R&R the EGR valve so the gasket cannot be placed on the studs before you slide on the valve. Maybe the gasket is missing or bent or maybe the EGR valve didn't get snugged down evenly?

Yes, those two studs were a real PITA to reinstall with the gasket but alas, I prevailed!

The leak is a simple hissing sound BUT, it can escalate to an ear piercing high pitch sound that goes away with the blip of the throttle! If I put my hand around the item circled in red, I can change the loudness of the hiss.

When I return home on Friday, I'll spray some WD-40 to see if the idle changes.

Keep 'em coming...
