I'm working on a 97 gt conv. sohc. I've had a problem with coolant loss since i got the car a month ago. I thought it might be due to a bad hose underneath the intake manifold. I removed the manifold and found leaves and fresh coolant in the valley, while looking around for where the coolant is coming from I found the drivers side spark plug holes are full of antifreeze. The hose under the manifold is fine, but I will replace it while it's available. There is not any water in the oil at all. Just want some more input but i believe the head must come off and head gasket replaced. I suppose it would also be prudent to check for a cracked head but there is no water in the oil. Thanks in advance.
