performing pressure test found coolant slowly coming down by timing chain into oil pan. Could this be head gasket?

It's on the drivers side dripping on the oil pick up tube
watched video that was real helpful
i guess I'm taking the front cover off
just bought the vehicle the guy said he had the head gasket replaced but it overheated when he was going up hills . He said his mechanic left it idle all day and never overheated . When I drain the oil I got a little bit of antifreeze at first but wasn't a whole lot
im going to do a timing belt there's a lot of slack in it

sorry meant timing chain
