So coolant is missing from the radiator pretty consistantly...and i am fairly ceritan that is no leak... so most likely a Head gasket and its going out the tail pipe? My oil is NOT milky and my coolant is not milky either??? fawk i hate when stuff doesn't work.

Exhaust smell sweet?

A pressure test and/or a compression gasses test will tell you for sure.

Most likely a cracked head, They are known to crack heads, or #7 cylinder has a crack in it.

My 6.2 had a pressurized overflow tank. Not uncommon for them to crack and leak.

My '93 6.5 had a similar problem. It was leaking around the tank on the side of the radiator just a little, but not enough to drip onto the ground, at least not while it was standing still. It eventually corroded from being wet all the time, killed the radiator and started dripping onto the ground.
