OK, I posted yesterday but I can't find it now so I'm going to try it again. I have oil bubbling up from between the manifold and the head. There is a slight recess in the casting of the block and it appears to be coming from there. My guess is it's just a gasket leak, but wondered if anyone else has seen this. There is no water in the oil so I think the block is nbot cracked or anything like that. Any pointers on changing the manifold gasket? This is my fist I/o always had outboards before this. Any help would be appreciated!
