Engine Block Rust

OK, did a search and didn't find anyone else mention this. I was under my truck today draining the water separator and look up at the engine block. There is an awful lot of rust scale on the drivers side right below the rear most soft plug on the engine block. Anybody else notice this on there truck. Wanted to check before I take it to the stealership.

Truck is an 05 6.0L.

Sounds like you have a soft plug leaking. If the coolant is up to snuff the rust is possibly external.

That was my first fear. Soft plugs are fine. Rust seems to be just external. I've just never seen an engine block flaking off big chunks of rust before and wasn't sure if this was a common problem or not.

Since you are in Ohio, the rust belt, I would not be surprised to see rust every where there is steel/iron on your truck.

Hit it with some scotchbrite and then some self etching primer.

yeah this rust belt is kicking my trucks a$#. I will try the scotchbrite and etch primer to help slow down the process. Guess that Caterpiller is looking better & better.
