The joint you circled is in the egr piping. If that piping has been blocked off then it is prone to collecting moisture, depending on where a block plate was installed. The seepage could simply be moisture buildup and not coolant at all.

If you want to check if the egr cooler is leaking then this video shows roughly how to do that...





-- The bigger concern is the "delete" program itself. Who did this programming,.. and If you have not already, you need to get the program properly reviewed. It does nt matter how much you think it 'runs ok".. because these engines will slowly eat their own guts out with bad delete programming, all while the truck owner swears that it runs great.

Also, in the photo that shows the whole side of the engine.. it is very evident that you have valve guide problems. The #4, #5 and #6 ports are covered in OIL,.. not coolant.

Any chance you can have any openings, in the next week or 2? I will just bring it to you.
