coolant issue
 

ok i have been loosing coolant somewhere for awhile and took a look and pressure tested it. its holding pressure but no coolant leaking anywhere. where would it be going if i dont see it and its not loosing pressure??? this is going against everything i know. could the head gasket be going out and only leaking when it gets to operating temps?

try looking for coolant stains under your hood, and all your lines.
look where your reservoir overflows.
is the car over heating or warmer than usual?

it does run a bit warmer sometimes but not all. the reservoir had a small hole about half way up but i sealed it up with rtv till i can find a reservoir that would work. ill drive it in a few days and do another pressure test after it warmed up.
