So I was washing the car over the weekend and when I popped the hood open to treat the plastics, I noticed this in the back of the engine. It looks a lot like what my BMW spit out when the water pump went out. Any thoughts? I sent these pictures to my service advisor and he said his master tech told him "It's nothing, just dirt." That just doesn't sound right to me...
PS. Jaguar replaced the water pump and supercharger about 10k miles ago.
Yea it does look like dirt. An unusual place for it, especially since it seems to be isolated right where valve cover gasket would leak. Spray the engine bay down, and clean that area, then wait to see it if returns.
Hard to tell just from a photo. I could see it as dirt or rust from just photos. The best way to tell is to clean one small area. If the metal is damaged underneath, it's not dirt.
Umm.. there are several other ways to definitively tell whether it's coolant or just dust (litmus paper?, hand loupe? Chemical analysis?) but tasting is one way. Or you could just smell it, because it does have a unique smell. Good thing these use propylene glycol and not ethylene glycol (which interferes with the nervous system, heart, kidneys and lungs' ability to work). You don't want to taste that stuff.
To the OP, the location is suspect. It could be coolant seepage, and it could be coolant or oil seepage collecting dirt/dust. Doesn't look like much. Just enough to dampen the surface slightly. Wash it down with some parts cleaner or brake cleaner to remove the residue that's collecting the dust. See if it returns over time.
The taste method has served me well for over half a century (and I still have partial kidney function). That looks like coolant residue and the location would certainly support that conclusion. As previously mentioned, coolant residue will taste sweet on the tip of the tongue.
