I have replaced 1 or 2 heads on 3 trucks in th past month. Pull your oil cap and see if water or moisture is in there. I would pull the valve covers off, you are going to change oil again after you install new heads. This may or may not be your problem, check everything else first.

No, mine were the W/P gaskets. I knew bout the oil cap trick. It appears milky if there's a prob.

I was just lookin for how many instances u had heard of.

Wow. it's crazy, i have check everything. has not found leak yet.?.. it only leak when i push truck hard. if i dont drive it hard it doesn't seem to leak.
i can't find trace of where it leak. seriously it's not even funny now.
i dont think it's head bolt or head gasket.

on my obs chevy, my water pump went out and there is a small valve on the bottom that was broken and leaking coolant. check the underside of the water pump and see if that's where it is coming from.

my mysterious leak ended up being water leaking past the head bolts, or so i was told. had moisture under cap. i was losing a lot of coolant.its parked now,i either have no oil pressure, or my gauge took a ****, im thinking the former.
