Yes, heads may also be damaged.
After warmed up running fine my ECT and EOT sometimes run just about the same temp usally see no more difference than about 15 degrees.
When towing I can get as much as 30 degrees when it's hot in the summer and pullin a big hill. So my ? Angry Hillbilly is looks and sounds fine to me but when I do my egr delete this spring should all I have to do if temps stay the same as present is just put a rebuilt kit in my oil cooler and maybe tank, wash out the exhaust manifold???
