1998 deville. I can smell antifreeze after it warms up but dont see it leaking. After it sits for a couple hours it starts to leak on the ground????? I can see small puddle on the top of the back of the block under the head area and in the valley. Ive seen it wet on top the heater control valve( I think thats what it is anyway). Drivers side of motor with big black motor on it. I havent taken a pressure tester to it yet. Ive looked at the crossover pipes a little bit on the back of the engine too. Those look ok. Nothing in the oil and exhaust looks ok. Any ideas on looking on the back of the motor?

I also having the fuel pump issue of not starting right away and after I shut it off it loses its pressure. From what I read its the valve in the pump. So I will need to find one of those too.

Thanks for all the help you can give.

 

Does not overheat either.
