I was losing antifreeze. Would fill overflow up then within one day the overflow would be empty. Shop reported losing antifreeze at manifold. Also replaced at the gaskets - Repair cost was right at $800 and solved my problem. Parts were $340 labor $470.
Same thing happened to me. The mechanic said something about it a while ago, but said it wasn't a big problem. More recently he said I needed to get it fixed. He replaced the gasket and now I am good to go. Cost me about $325 bucks.
