I recently pulled the end cap off the heat exchanger on my Perkins 6.354. It appears the coolant has congealed? Slimy looking stuff around the tubes. Has anyone experienced this and what is the cause?

I remember hearing that if you don't use anti-freeze specific for Diesel engines, that it may congeal. Something to do with the nature of the greater cylinder force as a result of higher compression, all of this kinda fuzzy, but when I cleaned out my freshwater cooling side of the system, I specifically used anti-freeze designed for diesel engines.

What color gel are you seeing? I lost a head gasket on dozer engine several years ago that was letting small amount of oil migrate to the coolant....I noticed brown gel in radiator tank. The oil is at greater pressure than your coolant system and a pinhole leak may not allow coolant back into the oil for you to see milky oil during changes or on dipstick.
