I purchaced a 99 K1500 Suburban with 103,000 miles recently. It is leaking coolant from the block to head on both heads, started about a week after purchace. There is a slight amount of moisture on the inside of the oil cap and inside of valve cover. Checked a couple of head bolts seemed to be torqued to spec. Looks like head gasket was just replaced.

Could this be from whoever did the work not using new head bolts? I paid $4750, It is clean inside and out. I have driven it on two 300 mile trips with no overheating issues at all. It was leaking coolant at the time of both trips, ran great now has a slight miss
