All,
Hoping this group can help me out. I've been using my father-in-laws truck (2003 3500 Duramax 6.6L) for the past few months for a house project and it has recently (last 2 week) developed a leak. I've tried to track down the issue but I'm not really sure what I'm looking at and having a hard time figuring it out.
While the engine is running and moving this leaks, when stopped and engine is off no additional leaks once cooled. This appears to be at the rear of the head on the passenger side. The leak is small, but after a longer drive it appears to leak significantly more
Photo 1 shows the general area, photo 2 shows the specific area the leak is coming from.
Any help or guidance you can provide is appreciated.
