    Water leak from exhaust manifold?

    Ok, so my 1992 SL650 has a Hose clamp around the exhaust manifold between the back and middle cylinders. It also appears there is a cap back there.

    I think it is leaking. What the hell is that cap for? Is it supposed to have a hose clamp around it, or was this a "fix" by a previous owner?

    I don't know what the plug is but I have a couple of guesses.

    It's a freeze plug and is designed to pop as opposed to cracking the manifold.
    Maybe a casting hole.
    Either way you can purchase the new plug #22 but my guess is the clamp is hiding something or is it possible, they were trying to hold the plug into place with the clamp?
    Have a photo??

    Well, its either leaking out the plug, or the cylinder to manifold, or both. I'll take it out (fun!) and see what the deal is.
