Installed new 16lb cap, sealing surface is good to go. I am going to install a bigger overflow tank tonight. I did notice this. After driving home from work (temp did not exceed 195) I parked the truck, and checked the overflow. It was dry, i left it that way.

After dinner I fired it up to record the exhaust for Dubie. I noticed a few small drops of moisture exiting both exhaust turn downs. I covered the exhaust with my hand and found it was getting ever so slightly wet, didn't feel like oil but also didn't smell much like coolant. After letting the truck warm up it seemed to disappear. No smoke noticed.

This makes me wonder if both heads have some sort of small crack. The head casting numbers are 462624, which are known to crack.

Is it time to do a leak down check?
