Why is my 6.0 "spotting" with coolant?
So I have to go through an inspection every morning (work at a nuclear plant) so I have to pop my hood every day. More often than not I get a faint smell of antifreeze. I can see some spots, not puking, but just a few red spots on the coolant tank. Its been like this for probably 6 months now. I'll wipe it off and no matter how I drive the truck, whether like a grandpa or like a bat out of hell within a week there will be a few more spots. I've added coolant once - maybe 1/5 gallon a couple months ago. I think that is gone again now.
I drove 45 miles on Monday night in a terrible hurry, drove it like it was a race car and never saw any abnormal temps and it never puked and I couldn't smell antifreeze.
Deltas are usually 1-4 degrees, never in any conditions do I see over 7*. No oil in the coolant that I can tell.
Just replaced the tank cap and still have the same problem.
What could be going on here?
