The hole with the plug I'm talking about doesn't go into the intake section. It doesn't go anywhere......it's just a threaded hole with extra casting around it. I doesn't mount anything either. Look at post #3. That's the manifold I'm talking about.
Now that is really strange looking. If it's just a threaded hole that doesn't go through, then I'd have to think something was mounted there, but have no idea what.
