I think I have been hit with the head gasket demon. I was doing my o/f change yesterday and I always check the underside of the engine while I'm down there . Well I noticed some weeping liquid coming from the driverside head gasket .Around the # 4 cylinder .It is mostly on the back side and bottom of the block by the firewall. It is a very little amount not enough to run down the block and drip on the ground . I can't tell what it is because it is black in color and feels gritty probable from picking up road dirt and sand from the beaches here . It almost looks like when you drop some oil while filling up you car and you don't clean it up ,it attracts the dirt and grime from the road . I then checked all the other areas and found no other weeping. I don't have to add any oil between changes . I am not losing any coolant and I don't have any overheating problems .I have checked the coolant tank after driving it appears normal . Is this normal for them to weep alittle or is it the start of head gasket problems . I have a 02 outback 2.5l 4eat with 37k miles on it .
