Things do happen in threes... like a network failure at work, a power outage at home involving a blown transformer (apparently our house has its own), and the leak is back! This leak happened about a year ago and just disappeared... Now its back and I fear its going to stay until I do something about it. Its leaking down the left side of the bell housing and it kind off looks like its leaking either from the left head gasket or the small hose under the intake chamber over the valley pan gasket. There isn't a puddle on the valley pan gasket, so I fear it is the head gasket ray: . Any input is greatly appreciated.
