Thats what I was thinking cranky. The pressure test didn't show any signs of a leak anywhere. But I have seen some white smoke in my exhaust a couple times so i'm hoping the head gaskets aren't bad again already. If it's not the gaskets I don't know how else the coolant would be getting into my cylinders. That was my original problem (coolant in cylinder 6) and the head gaskets that I replaced weren't in terrible shape so I might still be looking for another solution.
