I vaguely recall
that hole, just a round depression. It may well be covered with gasket material. As I recall I saw it, I pondered it, I forgot it. That was about 10 years and 700 hours ago.
I know folks say not to use gasket material. But what do you do when your nearest gasket is 3 weeks away? I use the Permatemp ultra high temp “copper” material and it works fine. Good up to something like 650°F. When I took the manifold off the gasket stayed adhered to the block, the gasket material makes up any imperfections. You need to be careful around the small holes that you don’t close them with it when it squeezes out. This is about the third time I’ve had this manifold off with the same gasket. But I did buy 2 new ones, just so I never have to do it again.
I even use it on my kerosene stove
, it will burn in a sustained flame. And on the exhaust elbow
on our big boats Yanmar
turbo. I consider it a necessary maintenance
